Answer:

9x^2 - 10x -4

Step-by-step explanation:

It is set up like this

     9x^2 - 8x

-              (x-2)2

First solve (x-2)2

the answer is (2x-4)

so now you can do this instead

    9x^2 - 8x

-              2x - 4

----------------------------------

9x^2 - 10x +4

9x^2 minus zero is 9x^2

-8x-2x is -10x

0- -4 is 4 because that is like saying 0 + 4 because double negatives equal a positive

A simpler way is to change all the numbers to the opposite sign and then change the minus to a plus

like this

    9x^2 - 8x

+              -2x + 4

----------------------------------

9x^2 - 10x +4

If m∠NOP = 24° and m∠NOQ = 110°, what is m∠POQ?
monitta

Correct answer for the above question is - option B. 86°

<u>Step-by-step explanation:</u>

Given:

∠NOP = 24°

∠NOQ = 110°

∠NOP and ∠POQ are adjacent angles

To Find:

∠POQ = ?

Solution:

Hereby, we can say that ∠POQ lies between line OQ and ON as given (∠NOP and ∠POQ are adjacent angles )

∠NOQ - ∠NOP = ∠POQ

∠POQ = 110° - 24°

<u>∠POQ = 86°</u>

Angle POQ is  86°

Thus we can conclude option B as correct answer.

I need help plz like ASAP

Answer:

1.25

Step-by-step explanation:

First we should fill in what we know. They mentioned that the y would be the numerator (# on the top) and the x would be the denominator (# in the bottom).

\frac{3}{24} =\frac{y}{10}         <----  This will be your proportion

Now we will cross multiply and make a equation. So we will do 3 * 10 which equals 30 and then 24 * y which is 24y. So now our equation will look like this.

30=24y\\y=1.25

Then when you solve the equation you'll get 1.25

Find the equation for the line that passes through the point (-4,5) and that is perpendicular to the line with the equation-3/2x
IgorLugansk [536]

Answer:

y = -4/3x - 1/3

Step-by-step explanation:

-3/2x+2y=-7

2y = 3/2x - 7

y = 3/4x - 7/2

y = -4/3x + b

5 = -4/3(-4) + b

5 = 16/3 + b

-1/3 = b
