Answer:
x² + 6
Step-by-step explanation:
Given
(4x² - 6x + 8) - (3x² - 6x + 2) ← distribute by - 1
= 4x² - 6x + 8 - 3x² + 6x - 2 ← collect like terms
= x² + 6
The estimated number of lines of code written by computer programmers per hour when x people are working & the correct option is y = 27x - 4.
Table showing the estimated number of lines of code written by computer programmers per hour when x people are working & option given y= 47 * 1.191ˣ y= 34 * 1.204ˣ y=26.9x - 1.3 y = 27x - 4
