Answer:
8, 9
Step-by-step explanation:
1/2x + 2(x + 1) = 22
1/2x + 2x + 2 = 22
1/2x + 2x = 20
5/2x = 20
5x = 40
x = 8
8, 9
4 + 18 = 22
Slope intercept form: y = mx + b
Equation: 682 = 40x
Slope = 40 (or 40/1)
Y-intercept = 0
In this case,
y = the total
x = the amount of minutes
y-intercept = 0, since there isn’t a b in the equation.
slope = 40, because y = mx + b is 682 = 40x
This should be correct, unless there is missing information in the question.
