In the triangle below, DF = x + 4 and AC = 4x – 6. Solve for x. Type your numerical
answer.

x= 7

Step-by-step explanation:

Midsegment theorem!

x+4 = 1/2 (4x-6)

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
