Y=-8x - 5
y=-4x - 5
what is the solution ?

(0,-5) x= 0; y= -5

Step-by-step explanation:

You can solve by using substitution. This means to solve for x on one of the equations then substituting x for the other equation and solving it.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
