(x-7) (-9) + (x-7) ( 4x+5)

The correct answer will be

Let's simplify step-by-step.

(x−7)(−9)+(x−7)(4x+5)

Distribute:

= (x)(−9)+(−7)(−9)+(x)(4x)+(x)(5)+(−7)(4x)+(−7)(5)

= −9x+63+4x2+5x+−28x+−35

Combine Like Terms:

= −9x+63+4x2+5x+−28x+−35

= (4x2)+(−9x+5x+−28x)+(63+−35)

= 4x2+−32x+28

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
