The following table shows the expressions that represent the sales of two companies: company a b sales 260(1.90)x 275(0.89)x which company has the largest percent of increase?
both company a and company b
neither company a nor company b
company a
company b

The company A has the largest percent of increase.

Step-by-step explanation:

The sales of two companies A and B are given as

......... (1) and  

......... (2)

Now, for x = 0 to x = 1, the sale value of company A will be given by equation (1) as 260 and 260 × 1.9 = 494.

So, the percentage of increase is

Again, for x = 0 to x = 1, the sale value of company B will be given by equation (2) as 275 and 275 × 0.89 = 244.75.

So, the percentage of decrease is

Therefore, the company A has the largest percent of increase. (Answer)

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
