The equations y = 36x represents the totals cost, y, in dollars, to hire Lavish Landscaping for x hours of work. The table represents the cost to hire Landscape Designs.
Which statement is true
Answers
If the cost equation, which represents the "total-cost" for "Lavish-landscaping" is "y=36x", then True statement is Option (c) because "Lavish-Landscaping" costs $12 per-hour-less than "Landscape designs.
To select the True statement, we compare the cost of Landscape Designs with the cost of Lavish Landscaping and determine the difference in cost per hour.
We can start by finding the cost per hour for Lavish-Landscaping using the given equation:
y = 36x,
Here, y represents the total cost in dollars and x represents the number of hours of work.
When x = 3, the total cost is $108,
So, the per-hour cost of "Lavish-Landscaping" is $36.
Next, we find the cost per hour for "Landscape-Designs" when x = 3,
For x = 3, the value of y is $144;
So, the per hour cost of "Landscape-Designs" is $48.
To find difference in cost-per-hour, we can subtract the cost per hour for Landscape Designs from the cost per hour for Lavish Landscaping:
⇒ $48 - $36 = $12;
This means that "Lavish-Landscaping" costs $12 "per-hour" less than "Lavish-Landscaping".
Therefore, the correct statement is (c).

A cell phone costs $750 and loses 28% of its value each year. Write an exponential decay function to represent this situation.
1. f(x)= 750 • 0.72^x
2. f(x)= 0.72 • 750^x
3. f(x)= 750 • 0.28^x
4. f(x)= 0.28 • 750^x
Answers
Answer:
1. [tex]f(x) = 750\cdot 0.72^{x}[/tex]
Step-by-step explanation:
The cell phone experiments an exponential depreciation, which is defined by the following formula:
[tex]f(x) = C_{o}\cdot (1-r)^{x}[/tex], for [tex]0<r< 1[/tex]. (1)
Where:
[tex]C_{o}[/tex] - Initial cost, measured in monetary units.
[tex]r[/tex] - Depreciation rate, no unit.
[tex]x[/tex] - Time, measured in years.
[tex]f(x)[/tex] - Current value of the cell phone, measured in monetary units.
If we know that [tex]C_{o} = \$\,750[/tex] and [tex]r = 0.28[/tex], then the exponential decay function that represents the situation is:
[tex]f(x) = 750\cdot 0.72^{x}[/tex]
Which means that correct answer is 1.

which of the given values will make the inequality n-93>175 true?
n=82
n=105
n=268
n=300
n=312
Answers
Answer:
n = 300 and n = 312
Step-by-step explanation:
n - 93 > 175
n > 175 + 93
n > 268
Therefore only the two last answers are are possible n values (n has to be more than 268, not equal)
The two numbers 300 and 312 will make the inequality n-93>175 true which are correct option (D)300 and (E)312.
What is inequality?Inequality is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is not equal.
Given inequality as:
n - 93 > 175
n > 175 + 93
n > 268
Therefore, n must be greater than 268 and not equal.
Hence, the two numbers 300 and 312 will make the inequality n-93>175 true.

D. 3n > 9.5
E. n-2<5
Answers
Answer:
Its just E
I'm sorry if I'm wrong
Answer: A, C, E
Solve for all the inequalitites.
n + 5 < 9
n < 9 - 5
n < 4
∴ n = 3 is a part of the solution set.
13n < 1
n < 1/13
∴ This definitely doesn't include n = 3.
3n + 1 > 7
3n > 6
n > 2
∴ n = 3 is part of the solution because n is larger than 2.
3n > 9.5
n > 9.5 ÷ 3
n > 3.16666666
∴ n = 3 is not part of the solution set.
n - 2 < 5
n < 5 + 2
n < 7
∴ n = 3 is a part of the solution set.

below are true? Select all that apply.
A The x-intercept is -8.
B The line has a positive slope.
C The y-intercept is 4.
D The line has a negative slope.
Answers
Answer: A, B, and C.
Step-by-step explanation: The answers you have selected in the picture are correct.
These are the actual claims made regarding the line:
The x-intercept is at - 8 because y = 0 when x = -8.
The line is growing and has a positive slope.
As soon as x = 0 and y = 4, the y-intercept is at 4.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
The true statements about the line are,
The x-intercept is at - 8, as when x = - 8 y = 0.
The line has a positive slope as it is increasing.
The y-intercept is at 4 as when x = 0 y = 4.

Each pair of polygons is similar. Find each missing side measure. two polygons 12 on top 5 on bottom second polygon 48 on top x on bottom
Answers
Answer:
[tex]x = 20[/tex]
Step-by-step explanation:
Given
First Polygon:
[tex]Top = 12[/tex]
[tex]Bottom =5[/tex]
Second Polygon
[tex]Top = 48[/tex]
[tex]Bottom =x[/tex]
Required
Find x
Since both polygons are similar, then:
[tex]Ratio = Top:Bottom[/tex]
For the first:
[tex]Ratio = 12:5[/tex]
For the second
[tex]Ratio = 48:x[/tex]
Equate both ratios
[tex]12:5 = 48:x[/tex]
Express as fraction
[tex]\frac{12}{5} = \frac{48}{x}[/tex]
Cross Multiply
[tex]12 * x = 48 * 5[/tex]
Solve for x
[tex]x = \frac{48 * 5}{12}[/tex]
[tex]x = \frac{240}{12}[/tex]
[tex]x = 20[/tex]
Steve studies math for 7/8 of an hour and history for 2/3 of an hour. How many hours did he study?
Answers
Answer:
The answer is 1 13/24 hours or 1 hour, 32.5 minutes
Step-by-step explanation:
Find a common multiple of the denominators 3 and 8, which would be 24. Convert the fractions:
7/8 x 3/3 = 21/24.
2/3 x 8/8 = 16/24
Add the two numerators = 37/24 or 1 13/24.
1/24 of an hour is 2.5 minutes, so 13/24 is 32.5 minutes.
The answer is 1 13/24 hours or 1 hour, 32.5 minutes
