Lucy is running a test on her car engine that requires her to be moving. The tolerance for variation i. her cars speed, in miles/hour, while tuning the test is given the inequality |x-60|< or equal to 3. Assume x is the actual speed of the car at any time during the test.
The minimum acceptable speed is?
The maximum acceptable speed is?

solution is : (4,4)

Step-by-step explanation: there will be one solution because the lines intersect at exactly one set of points.

(0,6)(6,3)

slope(m) = (3-6) / (6-0) = -3/6 = -1/2

y = mx + b

6 = -1/2(0) + b

6 = b

y = -1/2x + 6

(0,0)(6,6)

slope(m) = (6-0) / (6-0) = 6/6 = 1

y = mx + b

6 = 1(6) + b

6 = 6 + b

6 - 6 = b

0 = b

y = x + 0

x = -1/2x + 6

1/2x + x = 6

1/2x + 2/2x = 6

3/2x = 6

x = 6/(3/2)

x = 6 * 2/3

x = 12/3 = 4

P.S. I'm pretty sure the other guy is drunk XD
