Natasha2012 [34]

Answer: -5x^{2} -5x-10

Step-by-step explanation:

(2x^{2} -5x-7)-(7x^{2} +3)  

subtract by terms.

2x^2 - 7x^2 = -5x^2  

-5x  is the only term so leave it alone

Makenzie graphs the line y= 2x + 13. Which statement is true?
slamgirl [31]

Answer:

The point (-4,5) is on the line

Step-by-step explanation:

You can replace the x and y values to determine if it is a true statement

First Statement

5= 2(-4)+13 -> 5= -8+13 -> 5=5 true

Second Statement

-4=2(5)+13 -> -4= 10+13 -> -4 ≠ 23 false

You can automatically eliminate the next two answers because you already found that the first statement is true and because you can find points using an equation.
