Answer:
y = 1/2x + 4
Step-by-step explanation:
If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.
So solve for b: using y = mx + b
2 = 1/2(-4) + b
2 = -2 + b
4 = b
Put it all together
y = 1/2x + 4
The functions g and h are given by g(x) = x + 1 and h(x) = x²
Find the values of x for which hg(x) = 3x² + x - 5
Answer:
x = - [tex]\frac{3}{2}[/tex] , x = 2
Step-by-step explanation:
To find h(g(x)) substitute x = g(x) into h(x) , that is
h(g(x))
= h(x + 1)
= (x + 1)²
= x² + 2x + 1
For h(g(x)) = 3x² + x - 5 , then
3x² + x - 5 = x² + 2x + 1 ← subtract x² + 2x + 1 from both sides
2x² - x - 6 = 0 ← in standard form
(2x + 3)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = - [tex]\frac{3}{2}[/tex]
x - 2 = 0 ⇒ x = 2
f(x) = 5 – 0.2c and g(x) = 0.2(x + 5).

Answer:
$149.8
Step-by-step explanation:
40% of 350 is 140
7% of 140 is 9.8

If a vector gets multiplied by a negative number then its direction
A. remain same
B. gets reversed
C. gets half
D. gets double
Answer:
I believe it is B
Step-by-step explanation:
Answer:
B. gets reversed
Step-by-step explanation:
except that multiplying by a negative number will reverse the direction of the vector's arrow. For example, multiplying a vector by 1/2 will result in a vector half as long in the same direction, while multiplying a vector by −2 will result in a vector twice as long but pointed…

find area of trapezoid
Answer:
150 sqaure ft
Step-by-step explanation:
okay so the formula for area of a trapezoid is
1/2 (b1 + b2) h
so base one of 15 plus two of 10 os 25 ft
25 feet divided by 2 is 12.5 so 12.5 × 12 is 150
The question is in the picture
Answer:
y= -5x+7
Step-by-step explanation:
since it is parallel, the gradient is the same
m=-5
y=mX+C
y=-5x + c
sub in the coordinate to get the y intercept
(2)= -5(1)+c
2+5 = C
C=7
therefore the ans is :
y= -5x + 7

Give the number of terms:
cd + 3d2 – 2d
Give the number of terms
Answer:
3
Step-by-step explanation:
Given the expression
cd + 3d2 – 2d
We are to determine the number of terms
From the equation, the term so of the expression are cd, 3d^2 and -2d. From the listed functions, we can see that we only have three of them. Hence the number of terms in the expression is 3

Suzy needs a raise in her allowance to buy the new iPhone. In order to do so, she must make a total average of 90 in all of her classes. Her science average is an 85, her math average is a 92, her history average is a 95, and her choir class is a 95. Her English class is undetermined as of now. What does Suzy have to make in English to be able to receive her raise?
Answer:
83
Step-by-step explanation:
Total averages from the known classes
85+92+95+95=367
367+83=450
Divide 450 by the number of classes she has(5)
=90

Answer:
w+6=8 and w=2
Step-by-step explanation:
2(w+6) = 16
divide by two on both sides to remove the 2
w+6=16/2
w+6=8
-6 (remove six from both sides)
w=2

HELP ASAP IM GIVING BRAINLIEST For our safety, it is important that drivers recognize a stop sign immediately. Stop signs are made with exact side and angle measurements to form a regular octagon. They are red so they are easy to see. The three lines drawn below are straight lines. Lines a and b are parallel.
Answer:
a) The stop sign is a regular octagon, so the measure of ∠F must be 67.5°. What is the angle measure for ∠L? Describe the relationship between ∠F and ∠L. (1 point)
Angle L is 67.5 degrees. Angles F and L are opposite each other, yet the same angle-degree. Hope this helps <3

i need help telling if these are true or false
Answers:
FalseTrueFalseTrue======================================================
Explanations:
Point A is located at (0,1). It then moves to A' which is at (0,3). Note the y coordinate goes from y = 1 to y = 3, so the scale factor is 3/1 = 3 instead of 4. Therefore, the claim is false.Point A is at (-4,4). It moves to (-2,2). Each coordinate of (-4,4) is cut in half to get (-2,2). Cutting a value in half is the same as multiplying by 0.5, so point A fits the description. Let's find out if point B does as well. B is at (2,4) and it moves to B' (1,2); we can see that point B has its coordinates cut in half as well. Points C and D also work to fit the description (I'll let you check those coordinates) which means overall, quadrilateral ABCD dilates with a scale factor of 0.5 to get to quadrilateral A'B'C'D'. The answer here is "true".Point W is at the location (-1,1). Triple each coordinate to get (-3,3) which is where point W' should be located if we applied the dilation of scale factor 3. However, the diagram shows W' is not at (-3,3). It seems to be fairly close to (-2,2) if anything. We don't need to check the other points, but I recommend you do so just for practice. The answer here is "false".Because the scale factor is 0.25 = 1/4, this means "scale factor of 0.25" is the same as "scale factor of 1/4". That tells us to "multiply each coordinate by 1/4" which in turn is equivalent to "divide each coordinate by 4". Point E is at (-4,4) which moves to (-1,1) when we divide each coordinate by 4. Note how point E' is at (-1,1). So E moves in the proper way according to the instructions given to us. Points M, W and O also move in a similar fashion after we divide their coordinates by 4. The answer here is "true".36.2 cm

Which point is best represented by the ordered pair (2, -5.5)?
A point W
b point V
c point S
d point R
Answer:
B
Step-by-step explanation:
Answer:
The answer is A, Point W.
This is because (2, -5.5) is equal to (x, y). So, x would be 2, while point y will be -5.5. Point W represents this because it goes to 2 on the x axis, and down to -5.5 on the y axis.

Cassandra must share 10 1/2 kg of cookies in 3/4 kg bags. How many bags will she complete?
Show the work.
Answer:
She will complete 14 bags of cookies
Step-by-step explanation:
Here, we want to know the number of bags to be completed by the sharing
What we have to do here is to divide the total weight of the bag of cookies by what each cookie bag can take
We have this as;
10 1/2 kg divided by 3/4 kg
= 21/2 divided by 3/4
= 21/2 * 4/3 = 14 bags
