Answer:

4x + 5y = 20

Step-by-step explanation:

4x + 5y = 20

5y = -4x + 20      (Subtract 4x to isolate 5y. Put the 4x in front of the 20)

y = -\frac{4}{5}x + 4         (Divide all by 5 to isolate y)

And then it's done and in slope-intercept form

-1< -\frac{4}{5} < 0        or -\frac{4}{5} is greater than -1 but less than 0

I hope this helped :)

A blender that normally costs $130 is on sale for 12% off. What is the final cost of the blender if there is also an 8% sales ta
polet [3.4K]

Answer:

$105.25

Step-by-step explanation:

First we need to know to price of the blender after the sale, so we are going to pay the 88% of the blender's price so the final price without the sale tax is going to be

\$130\times .88=\$ 114.4      (1)

Knowing this price we need to calculate the 8% of the total price

\$ 114.4 \times .08=\$ 9.152    (2)

We substract the result (2) from (1)

\$ 114.4 - \$ 9.152 = 105.248

Rounding this number to nearest cent the final result is:

$105.25
