Which function has only one x-intercept at (-6, 0)?
f(x) = x(x - 6)
f(x) = (x - 6)(x - 6)
f(x) = (x + 6)(x -
f(x) = (x + 6)(x + 6)

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%
