Plug in the numbers
f(-4) = -3(-4)^2 - 4(-4) + 4
f(-4) = -48 + 16 + 4
f(-4) = -28
f(1) = -3(1)^2 -4(1) + 4
f(1) = -3-4+4
f(1) = -3
A) -28 - 3 = -31
B) -28 + 3 = -25

Step-by-step explanation:

<h3>Q1</h3>

<u>The ratios of corresponding sides of similar figures are equal:</u>

How do I complete this formal check?
natima [27]

Answer:

Step-by-step explanation:

The first two steps are for the purpose of eliminating fractions.  Doing so results in 4(2x - 5) = 9(x - 2), which is to be solved for x.

Perform the indicated multiplication, obtaining:

8x - 20 = 9x - 18.

Then combine like terms:  -2 = x, or

x = -2.

To complete the formal check, substitute -2 for x in the first equation.  This results in:

(1/3)(-4 - 5) = (3/4)(-2 -2), or

        -3       =        -3

... which is obviously true.
