Answer: y= (11/5)x+(64/5) or y=(11x+64)/5
Step-by-step explanation:
(y-y1)/(x-x1)=(y2-y1)/(x2-x1)
x1= -9, x2= -4
y1= -7, y2= 4
(y-(-7))/(x-(-9))=(4-(-7))/(-4-(-9))
(y+7)/(x+9)=(4+7)/(-4+9)
(y+7)/(x+9)=11/5
Cross multiply
5(y+7)=11(x+9)
5y+35=11x+99
5y=11x+99-35
5y=11x+64
y=(11x+64)/5
y=(11/5)x+(64/5)
3(2x+1)=15
6x+3=15
-3 -3
6x=12
divide each side by 6
x=2
Answer:
14, 28, 42, 56, and 70 are the first 5 common multiples of 14
20, 40, 60, 80, and 100 are the first 4 common multiples of 20
ANSWER
y = 3x + 6.50
EXPLANATION
The $3 for each downloaded movie is the unit rate of change.
This is represent the slope of the linear function that models this situation.
The monthly fee of monthly fee of $6.50 the constant rate.
It represents the y-intercept of the function.
The linear function is given by
The correct choice is y = 3x + 6.50
