Answer:

not linear

Step-by-step explanation:

this equation becomes y = -4x² + 32x which is a quadratic equation that, when graphed, forms an upside down u-shaped curve (upside down because the x² term is negative; if it's positive then the curve is u-shaped)

Answer:

Nonlinear

Step-by-step explanation:

Simplifying the function, we get:

y=4x(8-x)

y=4x*8+4x*(-x) (Distribute)

y=32x-4x^{2}

In a linear function, the highest power of x will be 1. This is not the case here as the highest power of x is 2 due to the -4x^{2}, which means that the given function cannot be linear. Therefore, the answer is nonlinear. Hope this helps!

A rectangle has a length that is three times the width . The perimeter of the rectangle is 40 feet.what is the area of the recta
charle [14.2K]

Answer:

The area is 15 feet

Step-by-step explanation:

So you are going to need two different equations-

l = w(3)

2l + 2w = 40

Insert the first equation into the second-

2(3w) + 2w = 40

Simplify this equation-

6w + 2w = 40

8w = 40

Divide both sides by 5

w = 5

Solve first equation

l = 5(3)

l = 15

Then find the area-

5 x 15 = 75

It is rational because any number that can be represented in a fraction is rational. 4/33 is a fraction, so it is rational.
