Answer:
b
Step-by-step explanation:
just took it i got 100%
If f(x) is = to 0 then that means that you would have to plug the 0 in for all of the x that are in the function and the solve it.
f(x)= x3-4x-1
f(0)= (0)3-4(0)-1
0 0 0 -1
-1
so that means that -1 would be the answer for the function
Answer:
6.3
Step-by-step explanation:
First off, we need the distance formula, which is:

If we plug in the points, we get:

If we simplify everything under the square root, we get:



In decimal, the answer is 6.3
Answer:
2x+2y ≤ 64
x=2y+2
Step-by-step explanation:
x = length
y = width
the length is 2 more than twice the width or 2 more than twice y
x = 2+2y
the perimeter of the garden = 2 times the length + 2 times the width
she have 64ft of wire so the perimeter should be equal or less than 64 ft
64 ≥ 2x + 2y
