Answer:

(a) $9x^2+16x-4$

(b) $9a(2a+5)$

(c) $(y-6)(y-4)$

Step-by-step explanation:

(a)

$(9x-2)(x+2)=$

$9x^2-2x+18x-4=$

$9x^2+16x-4$

(b)

$18a^2+45a=$

$9a(2a+5)$

(c)

$y^2-10y+24=$

$(y-6)(y-4)$

Hope this helps!

Answer:

$(-4,-5 )$

Step-by-step explanation:

You are looking for the point of intersection of these two functions.

Substitution:

This are now your formulas

$\left \{ {{x=-4y-24} \atop {5x+3y=-35}} \right.$

You are going to substitute x, so you can solve for y

$5(-4y-24)+3y=-35$
$-20y-120+3y=-35$
$-17y=85$
$y=-5$

Now you are going to substitute y to find x

$x=-4(-5)-24$
$x=20-24$
$x=-4$

Now lets check if it is correct

$-4+4(-5)=-24 :)$
$5(-4)+3(-5)=-35 :)$

So it is true, making (-4 , -5) your point of intersection.

hope it helps
