consider this expression:
–5x + 3 − 2x - 4
use the algebra tiles to combine like terms.
3 – 4 = –1
–5x – 2x =
x

-7

Step-by-step explanation:

3 – 4 = –1

–5x – 2x = x

–5x – 2x = -7x

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
