Answer:

(-7, -10)

x=-7\\y=-10

Step-by-step explanation:

4x-4y=12

Substitute x for -7.

4(-7)-4y=12

Multiply 4 by -7.

-28-4y=12

Add 28 on both sides.

-4y=40

Divide -4 on both sides.

y=-10

What is the discount of a guitar with an original price of $95 and a discount of 15%.
maks197457 [2]

Answer:

$80.75 dollars

Step-by-step explanation:

Given the following question:
Initial price = $95
15% discount

In order to find the answer, we have to find 15% of 95.

\frac{15\times95}{100} =15\times95=1425\div100=14.25
95-14.25=80.75
g=80.75

The guitar (after a 15% discount) costs "$80.75 dollars."

Hope this helps.
