The ideal width of a safety belt strap for a certain automobile is 4 cm. An actual width can vary by at most 0.35 cm. Write an absolute value inequality for the range of acceptable widths.

"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

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.

i believe the answer is y=0.25x+-3
