I’m not very good at math but here’s my reasoning:
x/2-7=9
I moved the 7 to the other side of the equation
So now
X/2 = 9 + 7
X/2 = 16
Since x is equal 16 if you divide x by 2 (because x/2=16), that means if you want to find x you need to multiply x by 2
X = 16 x 2
X = 32
I hope it’s right !! <3

Answer:

Step-by-step explanation:

x/2  - 7 = 9                  Add 7 to both sides

      <u>+7     7</u>

x/2 = 16                        Multiply both sides by 2

2*x/2 = 16*2        

x = 32

You are at about the second stage of solving equations. So far what you should know is that you should add or subtract before doing multiplication or division.

Take a much simpler question

x - 8 = 10        What do you do here? You can't multiply or divide. So add

<u>   +8    8</u>

x    =    18

Now try what you have

2x - 5 = 11                      Add before multiplication or division

  <u>   5      5</u>

2x = 16                          Divide by 2

2x/2 = 16/2

x = 8

O. Find the distance between P (10,-7) and Q (7,- 10). Leave your answer in radical<br> form.
mr Goodwill [35]

Answer:

\sqrt{18} or 3\sqrt{2} units.

Step-by-step explanation:

To find the <em>distance between two points</em>, we can use the Distance Formula.

Distance Formula: d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

<u />

<u>Given:</u>

P (10, -7) ⇒ x₁ = 10, y₁ = -7

Q (7, -10) ⇒ x₂ = 7, y₂ = -10

Substitute the given values into the formula and simplify.

\\\implies d=\sqrt{\bold{(7-10)}^2+\bold{(-10-(-7))}^2}\\\\\implies d=\sqrt{\bold{(-3)}^2+\bold{(-10+7)}^2}\\\\\implies d=\sqrt{9+\bold{(-3)}^2}\\\\\implies d=\sqrt{\bold{9+9}}\\\\\implies d=\sqrt{\bold{18}}\\\\\implies d=\sqrt{\bold{9}\times2}\\\\\implies d=3\sqrt{2}

The distance between points P and Q is \sqrt{18} or 3\sqrt{2} units.

Write the polynomial in standard form. Then name the polynomial based on its degree and number of terms.
Inessa05 [86]
Hey there.

When writing a polynomial in standard form, you always want to start from the highest degree (exponent), so let's simplify our expression before doing so.

-2x^{3} + 6x^{3} = 4x^{3};
This number will go first as it has the highest degree.
Up next will be '-3x', as it has a degree of 1.
After this, we have 6, having a degree of 0.

Let's set up our new polynomial with this information;
4x^{3} - 3x + 6.

This is known as a cubic trinomial since it has three terms and has a degree of 3.

Your correct answer is "D.)"

I hope this helps!
