Answer:

y = -12

Step-by-step explanation:

You first calculate the x coordinate using the equation x = $\frac{-b}{2a}$ , which in this case is $\frac{-8}{8} = -1$ .

Then plug that x value into the equation to get the y coordinate:

4(-1)²+8(-1)-8 = -12

Part A: Factor 3x2y2 − xy2 − 2y2. Show your work. (4 points)

Rudik [331]

A.

$3x^2y^2-xy^2-2y^2=y^2(3x^2-x-2)=y^2(3x^2+2x-3x-2)\\\\=y^2[x(3x+2)-1(3x+2)]=y^2(3x+2)(x-1)$

B.

$x^2+6x+9=x^2+2\cdot x\cdot3+3^2=(x+3)^2=(x+3)(x+3)\\\\\text{Used}\ (a+b)^2=a^2+2ab+b^2$

C.

$x^2-25=x^2-5^2=(x-5)(x+5)\\\\\text{Used}\ a^2-b^2=(a-b)(a+b)$

You buy four packages of shoelaces. You pay with a $10 bill and receive $3.24 in change. Determine the price of each package.

Mnenie [13.5K]

I think each package would be $1.69. first you subtract 3.24 from 10 to get what you payed then divide that by 4 to get 1.69
