You halve the linear coefficient, square that value, and add it.

In this case the linear coefficient is 5 so:

(5/2)^2

25/4

Completing the square would be (b/2)^2, where b here is equal to 5. (5/2)^2 would be 25/4, which would be choice B.

-3a - 3 = -2 + 3p ˢᴼᴸᵛᴱ ᶠᴼᴿ ᴬ

Hi!

$-3a - 3 = -2 + 3p$

$-3a=3p+1$

$\frac{-3a}{3}=\frac{3p+1}{-3}$

$Answer------>a=-p+\frac{-1}{3}$

Explanation: <u><em>First you had to add by 3 from both sides. It gave us -3a=3p+1. Then divide into -3 from both sides. It gave us -3a/-3=3p+1/-3, or a=-p+-1/3 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>

Earnings You work for 4 h on Saturday and 8 h on Sunday. You also receive a $50 bonus. You earn $164. How much did you earn per

marshall27 [118]

Hello there,

best way to do this one is set up your story line....

4h + 8h + 50 = 164$...

let's make this easier to look at and combine like terms..

12h + 50 = 164$...

Beautiful!!! Now let's try and get the h alone?...

minus 50 to both sides...

12h = 114$..

now divide both sides by 12...

H= 9.50$/hour

Looks like you made 9.50$ an hour but Hey, at least you got that bonus ;)

Given that (6 3) is on the graph of f(x) find the corresponding point for the function f(-1/2x)

Vlada [557]

$\bf \begin{array}{rllll}
(6&,&3)&f(x)\\
x&&y\\\\
(-\frac{1}{2}x&,&3)&f(-\frac{1}{2}x)\\\\
(-\frac{1}{2}\cdot 6&,&3)\\\\
(-3&,&3)
\end{array}$

keep in mind that, a negative coefficient to "x", will make the graph reflect over the y-axis.
