Answer:
The number of months cost same is 9
Step-by-step explanation:
Given:
Equation for the first plan y = 38x + 15
Equation for the second plan y = 31x + 78.
where x is the number of month
Solution:
38x + 15 = 31x + 78
7x + 15 = 78
7x = 63
x = 9
Answer:
They are parallel
Step-by-step explanation:
(3,8)(-6,5): do sloe formula (y1-y2 over x2-x1)
AB: 1/3 slope (Full formula y=1/3x+7)
(-6,7)(-3,8) ---> 8-7 over -3-(-6) = 1/3
CD: 1/3 slope (Full formula y=1/3x +9)
They have the same slope so they are parallel
Answer:
181.46 = A
Step-by-step explanation:
pi X r^2 is the area of a circle
the diameter is already given so you can skip the radius an jump straight into pi X d diameter = (r^2) giving you area pi X diameter
