Which line goes down from left to right?
A. y=2x+5
B. y=2x−6
C. y=2x
D. y=−2x+20

D. y=−2x+20

the correct answer is $7.38

step-by-step explanation:

"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
