Use the information below to answer the following question(s). An automotive manufacturer procures an important engine part. The tool that the manufacturer uses to monitor the part supplier is a supplier scorecard. With respect to part quality, two primary performance metrics monitored are parts per million (PPM) defects and percent PPM improvement. The following measures are used for the scoring criteria:

Simplify, where possible.6a - 4b + 2

A. -2a + 2 B. 2ab + 2 C. 6a - 4b + 2 D. 4ab

Solve the inequality. Write the solution in interval notation and graph the solution set. ? 3 + 

A. [-8, ?)

B. [8, ?)

C. (8, ?)

D. (-?, 8]

The sequence is defined recursively. Write the first four terms.a1 = y; an = an-1 + S

A. a1 = y, a2 = S, a3 = 2S, a4 = 3S B. a1 = S, a2 = S + y, a3 = S + 2y, a4 = S + 3y C. a1 = y, a2 = y + S, a3 = y + 2S, a4 = y + 3S D. a1 = y, a2 = y - S, a3 = y - 2S, a4 = y - 3S

Solve for the requested variable.y varies directly as z, and y = 208 when z = 13. Find y when z is 19.

A. y = 169 B. y = 304 C. y = 361 D. y = 256
