solve the inequality
y + 8 - 2(y - 20) > 0

a. y < -32
b. y < 48
c. y > 48
d. y > -32

C

Step-by-step explanation:

y+8-2y+40>0

-y+48>0

y > 48 (C)

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
