4x-8y=12 14+2x=-6y plz help

sesenic [268]

Answer:

x=2.7142 y=-2.8571,

Step-by-step explanation:

given 4x-8y=12............(1)

14+2x=-6y

2x+6y=-14..........(2)

from equ (2) multiply by 2

4x+12y=-28............(3)

substruct (1) and (3)

4x-8y-4x-6y=12-(-28)

-14y=40 ,y= $\frac{40}{-14}$ =-2.8571

y=-2.8571 put in equ (1)

4x-8(-2.8571)=12

4x=12-22.857=10.8571

x= $\frac{10.8571}{4}$

x=2.7142

Which statement best describes f(x)=-2sqrt(x-7+1)

andrew-mc [135]

Plugging -6 in for x, we get -2sqrt(-6-7+1)=sqrt(something negative) which is clearly not possible.

Plugging -6 in for f(x), we get -6=-2sqrt(x-7+1) and 3=sqrt(x-7+1). Squaring both sides, we get 9=x-7+1 and by adding both sides by 6 we get 15=x, therefore having (15,-6) and proving that -6 is in the range, but not the domain (B)
