Two cars are traveling along long straight roads which meet at right angles. Car A starts from a point 120 miles south of the intersection and travels north at a rate of 45 miles per hour. At the same moment car B starts 20 miles west of the intersection and travels west at a rate of 40 miles per hour. At what rate is the distance between the two cars changing 2 hours later

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

d is the only accurate one

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
