What algebraic expression must be added to the sum of 3x2 +4x+8 and 2x2−6x+3 to give 9x2−2x−5 as the result?

vesna_86 [32]

Answer:

$4x^2-16$

Step-by-step explanation:

-This is an addition/subtraction problem.

#We subtract the sum of the first two expression from the third expression:

$\#Add \ first \ two\\\\=3x^2 +4x+8 +2x^2-6x+3\\\\=5x^2-2x+11\\\\\# Subtract\ from \ the \ third\\=(9x^2-2x-5)-(5x^2-2x+11)\\\\=9x^2-2x-5-5x^2+2x-11\\\\=4x^2-16$

Hence, the expression $4x^2-16$ must be added to the first two.

If y =4when x= 10 find y when x=2

balu736 [363]

<span>Since y=4, when x=-2, plug it into the formula above, and you have
y=kx
4=k(-2)

Solve for k, k=-2

</span><span>Now, y = -2x, so if x=30</span>y=-2*30=-60.
