2x + y + z = 12
10.00 5x + 5y + 5z = 20
x - 4y + z = -21

1210.005"

Step-by-step explanation:

x+y+z=(1210005/1000)x+5y+5z=20x-4y+z=-21

1210005/1000

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

step-by-step explanation:
