Rearrange the equation so u is the independent variable.
-12u+13=8w-3

u = -2/3w + 4/3

Step-by-step explanation:

-12u + 13 = 8w-3

-12u = 8w - 16

u = -2/3w + 4/3

it's

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
