Check option C

y=-x²+16

Put (2,12)

12=-(2)²+16=-4+16=12

And

y=x²+8

Put(-2,12)

12=(-2)²+8=4+8=12

Hence verified

Option C is correct

Answer:

See below

Step-by-step explanation:

Find the value of y when x = 2 or x = -2 to determine the system

It is easy to calculate and confirm the correct equations

y = –x² + 16
y = x² + 8

See the attached to verify the answer

Answer:

1152 square feet

Step-by-step explanation:

<u>The dimensions of the container:</u>

w = 8 feet,
h = 12 feet,
l = 24 feet

<u>The area of the container is:</u>

A = 2(lw + hw + lh)
A = 2(24*8 + 12*8 + 24*12) = 1152 square feet

When 2(3/5x+2 3/4y-1/4x-1 1/2y+3) is simplified, what is the resulting expression?

erik [133]

Answer:

Option B is correct.

Step-by-step explanation:

$2(\frac{3}{5}x+ 2\frac{3}{4}y-\frac{1}{4}x-1\frac{1}{2}y+3)$

We need to solve the above expression.

First Convert Mix fraction into improper fraction

$2(\frac{3}{5}x+ 2\frac{3}{4}y-\frac{1}{4}x-1\frac{1}{2}y+3)\\=2(\frac{3}{5}x+ \frac{11}{4}y-\frac{1}{4}x-\frac{3}{2}y+3)$

Combining the like terms

$=2(\frac{3}{5}x-\frac{1}{4}x+ \frac{11}{4}y-\frac{3}{2}y+3)$

Solving like terms

$=2(\frac{3x*4-5x}{20}+ \frac{11y-3y*2}{4}+3)\\=2(\frac{12x-5x}{20}+ \frac{11y-6y}{4}+3)\\=2(\frac{7x}{20}+ \frac{5y}{4}+3)$

Multiply each term with 2

$=2*\frac{7x}{20}+ 2*\frac{5y}{4}+2*3\\=\frac{7x}{10}+ \frac{5y}{2}+6$

$=\frac{7x}{10}+ 2\frac{1}{2}y+6$

So, Option B is correct.
