Label each statement true or false, if false change underlined portion.

C. if -4 < -2t + 6 < 10 then this is underlined 2 > t + 6 > -5 I marked false, i think it should be -2 < t < 5.

D. If |y + 8| + 2 + 6, this underlined
this is not underlined: y + 8 = +4 -4
i marked it true

C.
-4 < -2t+6 < 10
-10 < -2t < 4
5 > t > -2

-2 < t < 5

D.
is that |y+8| + 2 = 6 ?
if so, then
|y+8| = 4
y+8 = 4 or y+8 = - 4
y = -4 or y = -12
