PLZZZZZZZZ HELP!!! AHHHHH

Alex

When you dilate the image by 3, you would multiply each value by 3. Since it's center is around 0, we really don't have to worry about much else.

-1*3= -3

-2*3= -6

0*3= 0

The new set of points are (-3,-6,0)

I hope this helps!

A car dealership manager has determined that the profit, in thousands of dollars, of the dealership can be determined by the exp

ss7ja [257]

Answer:

The number of cars that brings the same profit is 9 and 0

Step-by-step explanation:

Given

$x^2 - 4x = 5x$

Required

Determine the possible values of x

$x^2 - 4x = 5x$

Subtract 5x from both sides

$x^2 - 4x - 5x = 5x - 5x$

$x^2 - 9x = 0$

Factorize

$x(x - 9)= 0$

Split the equation

$x = 0$ or $x - 9 = 0$

$x = 0$ or $x = 9$

<em>Hence, the number of cars that brings the same profit is 9 and 0</em>
