Answer: 28
Step-by-step explanation:
2 × 8 = 16
8 + 4 = 12
12 ÷ 2 = 6
6 × 2 = 12
16 + 12 = 28
1/8x - 5 < - 8 7x - 4 > 38
+ 5 +5 +4 +4
1/8x < -3 7x > 42
÷1/8 ÷1/8 ÷7. ÷7
x = 24 x > 6

Remember, h(x) = y and x ...well, x is x...lol
B. h(x) = |x|....subbing in (-1,1)
y = |x|
1 = |-1|...absolute values are positive, even when they say negative
1 = 1 (correct)
