The annual salary of each employee at an automobile plant was increased by 6% cost of living raise and then $2000 productivity raise. a) write a function that transforms old annual salary, s, into the new one, n. b) state any transformations done on the old salary to get to new one.

a)  N = 1.06S +2000

b)  the old salary is scaled by a factor of 1.06 and translated upward by 2000.

Step-by-step explanation:

a) a 6% raise means the new salary is 100% + 6% = 106% of the old one. A raise of an additional dollar amount simply adds to the scaled salary.

b) The translations are "math speak" for the English description of "increased by 6% and then raised by 2000". "Increased by 6%" means that .06 of the amount is added to the amount, effectively multiplying it by 1.06. "Raised by 2000" means 2000 is added.

x=3

Step-by-step explanation:

For which x value is y 0?

First rewrite the equation to isolate y:

-2y = -18 + 6x

y = 9 - 3x

Now substitute y=0:

0 = 9 - 3x

3x = 9

x = 3
