Divide 240 by 45 you would get 5 and 1/3, multiply 5 and one third by 60 and it would result in 320.

D. 320 would be the correct answer.

Answer: See explanation

Step-by-step explanation:

15.) -7x + 6 (x - 8/2) - 2(x + 3) + 10

-7x + 6 (x - 4) - 2(x + 3) + 10

-7x + 6x - 24 - 2x - 6 + 10

Bring like terms together

-7x + 6x - 2x - 24 - 6 + 10

-3x - 20

16.) B, C, D

B. 3 (x + 2) + 4x

3x + 6 + 4x = 7x + 6

C. -2 + 4(x + 3)

-2 + 4x + 12 = 4x + 10

D. 3x + 5(x - 1)

3x + 5x - 5

8x - 5

17.) A, B, D

A. 1/5(x - 50)

1/5x - 10

B. 1/6(-x + 12)

-1/6x + 2

D. 1/2(x + 16)

1/2x + 8

Someone help me please☹️

Levart [38]

Answer:

my best advice: look at the y-intercepts!

Step-by-step explanation:

when the equations are set out like this, the last number (in this case "+4" and "-2"), represents where they cross the y axis. this gives you a great place to start.

if you plot (0, 4) for the first equation, you can then move right one square and down one square to get the next point in the equation.

the next one starts with (0, -2) and goes right one square and up two

Write y=2x^2+12x+14 In vertex form

ratelena [41]

Answer:

$\large\boxed{y=2(x+3)^2-6}$

Step-by-step explanation:

The vertex form of a parabola f(x) = ax² + bx + c:

$y=a(x-h)^2+k$

(h, k) - vertex

$h=\dfrac{-b}{2a}\\\\k=f(h)$

We have the equation:

$y=2x^2+12x+14\\\\a=2,\ b=12,\ c=14\\\\h=\dfrac{-12}{2(2)}=\dfrac{-12}{4}=-3\\\\k=f(-3)=2(-3)^2+12(-3)+12=2(9)-36+12=18-36+12=-6$

Finally:

$y=2(x-(-3))^2+(-6)=2(x+3)^2-6$

Under his cell phone plan, Elijah pays a flat cost of $64.50 per month and $5 per gigabyte. He wants to keep his bill at $87.50

timofeeve [1]

Step-by-step explanation:

Plan A: A = 20G

Plan B: B = 15G + 40

To see when they will be equal set the equations equal to each other

20G = 15G + 40

5G = 40

G = 8

At 8 GB they will cost the same amount.

20(8) = $160

15(8)+40 = $160

Hope it will be Helpfull

thank you
