Answer: 3 months
Step-by-step explanation:
Let x be the number of months and A and B the total costs for each service.
A = 45 + 65x
B = 80x
We want to know the months that would make A = B:
A = B, solve for x, months.
45 + 65x = 80x
45 = 15x
x = 3 months
After 3 months, Company A will be less expensive.

Answer:
Multiply both sides by 3
Step-by-step explanation:
The best step would be to multiply both sides by 3 so that there are no fractions in the equation.

Answer:
y = ⁷/5x + 34/5
Or
y = 1.4x + 6.8
Step-by-step explanation:
To find the equation of the line in the slope-intercept form, y = mx + b, we have to determine the value of:
Slope (m) = change in y/change in x
y-intercept (b) = the y-coordinate of the point where the y-axis is intercepted by the line
Using the two points indicated in the line, (-7, -3) and (-2, 4),
Slope (m) = (4 - (-3))/(-2 - (-7)) = 7/5
m = ⁷/5
To find b, substitute m = ⁷/5 and (x, y) = (-2, 4) into y = mx + b
4 = ⁷/5(-2) + b
4 = -14/5 + b
4 + 14/5 = b
(20 + 14)/5 = b
34/5 = b
b = 34/5
To write the equation, substitute m = ⁷/5 and b = 34/5 into y = mx + b
y = ⁷/5x + 34/5
Or
y = 1.4x + 6.8
