Answer:
domain: 0 ≤ m ≤ 44,640
range: 20 ≤ C ≤ 2252
Step-by-step explanation:
Haley cannot possibly use her phone more than 24 hours a day for 31 days in a month, so the number of minutes in a month puts a limit on the domain of the function.
The upper end of the range is correspondingly limited.
The number of minutes cannot be negative, and C will have a minimum value of 20.
Answer:
y=2x+5
Step-by-step explanation:
The equation of a line in slope intercept form is written as: y=mx +b where m is the slope and b is the y-intercept.
Taking point (-1,3) , m= 2 and imaginary point on the line, (x,y) then ;
m=change is y-coordinates/change in x-coordinate
m=Δy/Δx
m=y-3/x--1
2= y-3 / x+1
2(x+1) = y-3
2x +2 =y-3
2x=y-3-2
2x=y-5
<u>y=2x+5 is the equation.</u>

Answer:
![x=10](https://tex.z-dn.net/?f=x%3D10)
Step-by-step explanation:
Here, we can use an angle rule.
We see that angles
° and 130° are under a sort of F shape, where lines m and n are the horizontal parts of the letter and where the diagonal line is the vertical part of the letter.
This means we can use the rule:
Corresponding angles are equal.
This means that:
![8x + 50 = 130](https://tex.z-dn.net/?f=8x%20%2B%2050%20%3D%20130)
We can now use this equation we have formed to solve for
:
![8x + 50 = 130\\8x = 80\\x = 10](https://tex.z-dn.net/?f=8x%20%2B%2050%20%3D%20130%5C%5C8x%20%3D%2080%5C%5Cx%20%3D%2010)
Therefore, our final answer is
.
