Answer:
Company A: 
Company B: 
Step-by-step explanation:
The initial fee is the y-intercept, as that is the cost at x = 0, or the cost before any time has passed. Afterwards, the rate the cost increases is the slope.
Linear equation in slope-intercept form:

where m is the slope and b is the y-intercept.
Company A charges $50 up front and $40 per hour afterwards, so the equation would be:

Company B charges $25 up front and $50 per hour, so:

Solve your equation step-by-step.
2(x−3)−17=13−3(x+2)
Simplify both sides of the equation.
2(x−3)−17=13−3(x+2)
Simplify
2x−23=−3x+7
Add 3x to both sides.
2x−23+3x=−3x+7+3x
5x−23=7
Add 23 to both sides.
5x−23+23=7+23
5x=30
Divide both sides by 5.
5x/5 = 30/5
x=6
Hey there!
All of the angles of a triangle add up to 180. We already have 65+79 which is 144. This means only need 36 more degrees to get to 180.
Therefore, your answer is A) 36°.
I hope this helps!
For this case we have the following exponential function:

To find the value of f (-2) what we must do is substitute the value of x = -2 in the given function.
We have then:

Then, rewriting the function we have:

Finally, simplifying we have:
Answer:
The value of f (-2) is:
option B
