#1 Solving systems of equations by elimination

Show work please!!

x=3 y=-4

Step-by-step explanation:

i graphed them and found the intersection between them.

-4(3)-2(-4)=-4           -12+8=-4        -4=-4   so correct

3+-8=-5      -5=-5 so correct

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
