If f(x) = - 2x2 + 2x - 3, what is f(5)?<br><br> A) -93 <br> B) -43 <br> C) -28 <br> D) -<br> 43/5
andrew-mc [135]

Answer:

The answer to your question is letter B

Step-by-step explanation:

Process

1.- Write the function

                                 f(x) = - 2x² + 2x - 3

Find f(5)

2.- Substitute x for 5

                                f(5) = -2(5)⁵ + 2(5) - 3

3.- Simplify

                                f(5) = -2(25) + 10 - 3

                                f(5) = -50 + 7

                                f(5) = -43

Given and proof with the figure below. <br> Complete the following proof
nevsk [136]

Answer:

2 step proof, Subtraction Property

Step-by-step explanation:

This one is pretty easy if you know a shortcut. Addition, Subtraction, Multiplication, and division properties.

Think about it this way. Subtract angle 1 from QUS. Then subtract angle 2 from RUT. Knowing RUT is equal to QUS means that the differences are the same.

Don't know if this is right or not but hope this helps.

Here's my work
