The value of y = 40.
5x = 40
x = 8
180 = 40 + 40 + (2y + 20)
40 = y
So how you find the x-intercept is is by replacing y, with 0 and solve
to find the y-intercept, you replace x with 0 and solve
x-int:
0=-3x+12
-12=-3x
x=4 --> (4,0)
y-int:
y=-3(0)+12
y=0+12
y=12 --> (0,12)
Answer:
k+7
k-7
or k+7/k-7
Step-by-step explanation:
The ratio of circumference to diameter is independent of the radius.
Defining C=circumference, r=radius, D=diameter = 2r
Circumference = C = 2 π r = π D
=>
ratio of circumference / diameter
= C/D = π
C is the answer since you are trying to make the ys number (-/+) of the value the other y contains
(3) so you will multiply the first equation by -3 to be able to eliminate y
