Answer:

Part A number 2 (see work below)

*please give me brainliest lol*

Step-by-step explanation:

(8r^3 + 2r^2 + 1) - (7 - 7r^3 + 3r^2)

after factoring out the negative, you'll have:

8r^3 + 2r^2 + 1 -7 + 7r^3 - 3r^2

now we combine like terms, and your answer is:

15r^3 - r^2 - 6

PLSSSS HELPPP>> Show work solve the sysytem- y=1/2x^2+4x+4 y=-4x+12 1/2

vekshin1

Answer:

The solution is (-17,80.5) and (1,8.5)

Step-by-step explanation:

Equation 1 : $y=\frac{1}{2}x^2+4x+4$

Equation 2: $y = -4x+12.5$

Substitute the value of y from equation 2 in equation 1

Equation 1 : $y=\frac{1}{2}x^2+4x+4$

After substitution :

$-4x+12.5=\frac{1}{2}x^2+4x+4\\\frac{1}{2}x^2+8x+4-12.5=0\\\frac{1}{2}x^2+8x-8.5=0\\x^2+16x+17=0\\x=-17,2$

Substitute the value of x = -17

y = -4x+12.5

y = -4(-17)+12.5

y=80.5

Substitute the value of x = 1

y = -4(1)+12.5

y=8.5

Hence the solution is (-17,80.5) and (1,8.5)
