F the value of x decreases by 6, how does the value of m(x + 9) change?

Yuki888 [10]

start with y= m(x+9)

Use the distributive property:

y= mx+9m

Now you want x to decrease by 6:

so y ' = m(x-6) + 9m

Use distributive property again:

y'= mx - 6m + 9m

y' = (mx+9m) - 6m

y' = y - 6m

So the value of y decreases by 6m.

The manufacturer's price for a cooler is $28.50 A camping store that buys the coolers sells them for $40.76 What is the approxim

Nutka1998 [239]

The percent of the increase is

$I=\frac{N-O}{O}\times100$

I is the increasing value

N is the new value

O is the original value

The price of the cooler is $28.50, then

O = 28.50

The selling price of the cooler is $40.76, then

N = 40.76

We will substitute them in the rule above to find I

$I=\frac{40.76-28.50}{28.50}\times100$

Let us calculate it

I = 43.0175 %

Round it to the nearest percent

I = 43%

The answer is D
