Add like terms from both trinomials:

$4x^{2} + -2x^{2} = 2x^{2}$
$2x + -5x = -3x$
$-1 + 3 = 2$

Combine these terms to get a new trinomial as your answer:

$2x^{2} - 3x + 2$

13.
Subtract like terms from both trinomials (note that subtracting a negative is the same as adding it as a positive):

$3x^{2} - 5x^{2} = -2x^{2}$
$-8x - -11x = -8x + 11x = 3x$
$-1 - -1 = -1 + 1 = 0$

0 can be left out of the answer.

Combine these terms to get a binomial as your answer:

$-2x^{2} + 3x$

The function rule of a certain function is y = -3x + 1. If the input is 7, what is the output?

Answer:

-20

Step-by-step explanation:

y = -3x+1

if the input is 7, it means x=7 so substitute in the equation

y= -3*7+1 = -21+1= -20 which is the output
