Consider the function shown on the graph
which function does the graph represent?
(8, 15)
f(x) = (x + 3)(x + 7)
f(x) = (x – 3)(x-7)
f( x) = 3(x - 3)(x-7)
f(x) = 11(x + 3)(x + 7)

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

it would take 5 hours i think idk i'm not that good at math.can you me with my questions i need asap.

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%
