Step-by-step explanation:
Substitution: Two
Use substitution to prove that your two expressions are equivalent.
7(9j+ 6j + 2)
63j + 14 + 42j
63 x 1 + 42 x 1 + 14
63 x 1= 63
42 x 1=42
42 + 63 + 14
42 + 63 = 105
105 + 14 = 119
Part 2: Writing Expressions
Substitution : One
2. Translate the algebraic expression you created in Question 1 to a verbal expression
The product of seven and the sum of the product of nine and some number, two, and the product of six and some number.
Use substitution to prove that your two expressions are equivalent.
7(9j+ 6j + 2)
7( 9 x 1 + 6 x 1+ 2 )
9 x 1= 9
6 x 1= 6
7 ( 9 + 6 + 2 )
9 + 6 = 15
15 + 2 += 17
7 x 17 = 119
Part 1: Writing Expressions
1. Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
My expression is 7(9j+ 2 + 6j) .
Writing Equivalent Expressions
Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.
You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
7(9j+ 2 + 6j) = 7(9j+ 6j + 2) = The Commutative Property of Addition.
7(9j+ 2 + 6j) = 63j + 14 + 42j = The Distributive Property

Ann had twice as many candies as Susan. Then Ann ate 3 of her candies.
This can be modeled using the following equation:
A = 2s - 3
Solve the equation for the number of candies Susan has, S
S = A + [?]/[?]
Answer: S = [tex]\frac{A}{2}[/tex] + [tex]\frac{3}{2}[/tex]
Step-by-step explanation: Isolate S by timesing it by 2, which means you have to times A and 3 by two and take S to the other side of the equation which makes the minus into a plus.
Answer:
[tex]S=\frac{A+3}{2}[/tex]
Step-by-step explanation:
The original equation is:
A=2S-3
But, we are now solving for S, so we have to isolate S.
To do this, we first must add 3 to both sides:
A+3=2S
Next, divide both sides by 2:
[tex]\frac{A+3}{2}=S[/tex]

Triangle JKL has vertices at J(−1, −5), K(−2, −2), and L(2, −4). Determine the translation direction and the number of units of the image of triangle JKL if vertex J′ is at (−1, −8).
3 units down
3 units up
7 units to the right
7 units to the left
Answer:
3 units down
Step-by-step explanation:
J(-1, -5) → J'(-1, -8)
The x coordinate of the vertex J is -1 and does not change in J' (it is still -1)
The y coordinate of J is -5, and for J' is -8. This means the translation direction of 3 units down. (-8- -5 = -3)

Firstly, you have to understand that if you talk about slope is a similar word gradient of the graph. So if you are calculating slope you have to use gradient formula:
m= Y2-Y1
X2-X1
therefore, in order for you getting first box & second box you have to use this formula above.
First box answer is:
Points fromthegraph (-2:-2) & (-3:-3)
m= Y2-Y1
X2-X1
m = -3-(-2)
-3-(-2)
m = 1
Second box answer is:

six times the sum of a number and 4 equals 5. Please turn it into an equation :}
Answer:
6(x + 4) = 5
Step-by-step explanation:
We can break this sentence down into individual operations:
"six times" → this means 6 multiplied by some quantity
6 · ()
"the sum of a number and 4" → this is the quantity that we can put inside the parentheses (Note that "a number" is represented as a variable x, and a "sum" is the result of the addition of multiple numbers.)
6 · (x + 4)
"equals 5" → this is self-explanatory; the expression above is equal to 5
6(x + 4) = 5
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
Note that multiplication with a value inside parentheses is implied.
For example,
4(5) = 4 · 5 = 20
⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯⎯
We can solve for x in this equation to solve for "a number".
6(x + 4) = 5
↓ applying the distributive property ... a(b + c) = (a · b) + (a · c)
6x + (6 · 4) = 5
↓ simplifying
6x + 24 = 5
↓ subtracting 24 from both sides
6x = -19
↓ dividing both sides by 6
x = -19/6

How far did I travel to reach my destination on each day of my three-day Trip?
a. On Day 1, after traveling 5/8 of the way to the first day's destination, I still had 15 miles left to go before reaching my first destination.
b. On Day 2, after traveling 18 miles, I still had 2/5 of that day's distance left to go before reaching my second destination.
c. On Day 3, after traveling 5/11 of that day's distance, I still had 6 more miles to travel than what I had already traveled that day, before reaching my third destination.
The total distances you traveled to reach your destination on each day of your three-day trip are as follows:
a) Day 1 = 40 miles
b) Day 2 = 30 miles
c) Day 3 = 11 miles.
How the total distances are determined:The total distances are determined using proportions.
Proportion refers to the fractional value of the whole number or quantity.
a) Day 1:
The fractional distance traveled = ⁵/₈
The remaining distance to travel = 15 miles
15 miles = ³/₈ (1 - ⁵/₈)
Proportionately, the total distance = 40 miles (15 ÷ ³/₈)
b) Day 2:
The distance traveled = 18 miles
The remaining distance to travel = ²/₅
The distance traveled = ³/₅ (1 - ²/₅)
³/₅ = 18 miles
Proportionately, the total distance = 30 miles (18 ÷ ³/₅)
c) Day 3:
The distance traveled = ⁵/₁₁
The distance to travel = 6 miles
The distance to travel in fractions = ⁶/₁₁ (1 - ⁵/₁₁)
Proportionately, if 6 miles = ⁶/₁₁, the total distance = 11 miles (6 ÷ ⁶/₁₁)

Find the best measure of variability for the data and determine which player was more consistent.
Player A is the most consistent, with a range of 7.
Player B is the most consistent, with a range of 9.
Player A is the most consistent, with an IQR of 2.5.
Player B is the most consistent, with an IQR of 3.5.
To find the best measure of variability for the data and determine which player was more consistent, we can calculate the range and the interquartile range (IQR) for both players.
The range is calculated by subtracting the minimum value from the maximum value in a dataset. The IQR is a measure of dispersion that represents the range between the first quartile (Q1) and the third quartile (Q3) in a dataset.
Let's calculate the range and IQR for both players:
For Player A:
The data for Player A is: 2, 1, 3, 8, 2, 3, 4, 4, 1.
To calculate the range:
[tex]\text{Range} = \text{maximum value} - \text{minimum value}[/tex]
The maximum value is 8, and the minimum value is 1.
[tex]\text{Range} = 8 - 1 = 7[/tex]
For Player B:
The data for Player B is: 1, 4, 5, 1, 2, 4, 5, 5, 10.
To calculate the range:
[tex]\text{Range} = \text{maximum value} - \text{minimum value}[/tex]
The maximum value is 10, and the minimum value is 1.
[tex]\text{Range} = 10 - 1 = 9[/tex]
To calculate the IQR, we need to find the first quartile (Q1) and the third quartile (Q3) for each player:
For Player A:
Arranging the data in ascending order: 1, 1, 2, 2, 3, 3, 4, 4, 8.
To calculate Q1, we find the median of the lower half of the data: 1, 1, 2, 2, 3.
Q1 = 2
To calculate Q3, we find the median of the upper half of the data: 3, 4, 4, 8.
Q3 = 4
The IQR is calculated as:
[tex]\text{IQR} = Q3 - Q1[/tex]
[tex]\text{IQR} = 4 - 2 = 2[/tex]
For Player B:
Arranging the data in ascending order: 1, 1, 2, 4, 5, 5, 5, 10.
To calculate Q1, we find the median of the lower half of the data: 1, 1, 2, 4.
Q1 = 1.5
To calculate Q3, we find the median of the upper half of the data: 5, 5, 5, 10.
Q3 = 5
The IQR is calculated as:
[tex]\text{IQR} = Q3 - Q1[/tex]
[tex]\text{IQR} = 5 - 1.5 = 3.5[/tex]
Based on the calculations, we can conclude:
Player A is the most consistent, with a range of 7.
Player B is the most consistent, with a range of 9.
Player A is the most consistent, with an IQR of 2.
Player B is the most consistent, with an IQR of 3.5.
Therefore, the correct answer is:
Player A is the most consistent, with an IQR of 2.

Indiana plans to purchase a new gaming system during the 15% off sale. Let c represent the cost of the gaming system. How can you write a function to represent this?
Indiana also knows that he will have to pay the state tax of 10% on his purchase (after the discount is taken). Let p represent the price. How can he write a function to represent this?
Write one single function to help Indiana know how to calculate the final cost.
Answer:
The single function to calculate the final cost of the gaming system, including a 15% off discount and a 10% state tax, is: final_cost(c) = 0.935c.
Step-by-step explanation:
To represent the cost of the gaming system before any discounts or taxes, we can use the variable c:
c represents the cost of the gaming system.
To represent the price after the 15% off discount, we need to calculate the discounted price by subtracting 15% of the cost from the original cost:
p = c - 0.15c
Simplifying, we get:
p = 0.85c
Here, p represents the price after the 15% discount has been applied.
To represent the price after the 10% state tax has been added to the discounted price, we need to calculate the price with the added tax:
final_price = p + 0.1p
Simplifying, we get:
final_price = 1.1p
Here, final_price represents the price after the 10% state tax has been added.
Therefore, the correct single function to help Indiana calculate the final cost is:
final_cost(c) = 1.1(0.85c)
Simplifying further:
final_cost(c) = 0.935c
4. If the base of a parallelogram is 61 m and the area is 645 m2, what is the height of the parallelogram
Answer:
10.57 m
Step-by-step explanation:
Let the height of the parallelogram be x m
Area of the parallelogram = base*height
645 = (61 * x ) m
x = 645/61
= 10.57 m
Hope this helps
Height of parallelogram = 10.57m
Given,
Base of parallelogram = 61 m
Area of parallelogram = 645 m²
Now, according to formula
Area of parallelogram = Base × Height
Substitute the given values in the formula,
645 = 61 × height
Height = 10.57 m
Hence, the height of the parallelogram with area 645m² and base 61 m is 10.57 m .
