5 is not a function because if you draw a vertical line then it touches twice which is not a function
6 is a function
7 is not a function because there are 2 of the same inputs
8 is a function because it passes the vertical line test
9 is not a function
10 is a function
Hopefully that helped!
Answer:
A. -25

Divide both numbers by 13/90
13/90x = 130
÷13/90 ÷13/90
x= 900
Answer: 0, 1, -3
Step-by-step explanation:
f(x) = x^3 +2x^2 -3x
f(x) = x(x^2 +2x-3)
f(x) = x(x-1)(x+3)
to find zeroes, plug into f(x) and solve for each value of x. doing this gives 0, 1, and -3
X=4
First find the solution to (x+1) ft. I chose to guess the answer as 4 and it worked (you’ll have to guess). I then plugged 4 into the other equation 2x. It became 2•4. Solving give the side length of 8 ft. Then you have to check to make sure they both have the same area. To do this just solve the equations.
First rectangle- 4•4= 16 ft area
Second rectangle- 2•8 = 16 ft area
( I’m really sorry if this is confusing)
