Answer: 43feet
Step-by-step explanation:
Perimeter= 135 feet
Since perimeter= 2πr
135 = 2πr
Recall that π = 3.14
135 = 2 × 3.14 × r
135 = 6.28 × r
135 = 6.28r
r = 135/6.28
r = 21.5
d = 2r
d = 2 × 21.5
d = 43 feet
Answer:
The answer is C. The slope is 3 and y-intercept is (0,-1(
Rearrange the formula so that its in the form of y=mx+b
so it would be:
8y= -4x + 4
then divide by 8:
y= -4/8 x + 4/8:
Simplify:
y= -1/2x + 1/2
the slope is -1/2
Answer:
-12
Step-by-step explanation:
Note that when x < 6, you will use the expression -4x
f(x) = -4x
Plug in 3 for x
f(3) = -4(3)
Simplify. Multiply
f(3) = -4(3)
f(3) = -12
-12 is your answer
