P= 2L + 2 W = 50 P=50
W= L+ 5 Plug into equation (substitution)
2L +2 L+5 = 50
4L=50 -5
L= 45/4
L=11.25
P= 2 L + <u>(2 L +5)</u> = 50
P= 2(11.25) + 2(11.25) +5 =50
P=22.5 + 27.5
P=50 2L=22.5 and 2W= 27.5
L=11.25 W= 13.75
Answer:
C) C(x) = 5 +0.25x
Step-by-step explanation:
Let
C(x) ---> the total cost monthly
x ---> is the number of hours in a month
we know that
he linear equation in slope intercept form is given by
where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
The slope is equal to
The initial value or y-intercept is equal to
substitute
5.3 and 5.30 would probably be best i think
Answer:
Subtract by 5 on both sides.
Step-by-step explanation:
x+5 = -10. if you subtract both sides by 5, you will get x+5-5=-10-5, which can be simplified to x=-15.
