Answer:

x=8

Step-by-step explanation:

5(x – 2) = 30

Distribute:

5x - 10 =30

Add 10 to both sides:

5x = 40

Divide

x=8

Check your work:

5(8 - 2) =30

5(6) =30

5 * 6=30

30=30!

Final answer: x=8

Answer:

(0, -3)

Step-by-step explanation:

Coordinates are set up like this: (x, y)

You move none across on the x plane, so (0,y).

You move 3 down on the y plane, so (0, -3).

Hope this helps!

Answer:

B. (0,-3)

Step-by-step explanation:

If you were to do coordinates you would always start with the x-axis then the y-axis. So in this case 0 = X-axis and -3 = Y-axis. If you had a harder problem then there would also be a Z-axis. Hope this helps have a good day :D

Answer:

3/8

Step-by-step explanation:

There are 8 cupcakes. Juan gets 4 and there are 4 left. Elena gets 3 out of the 4 that are left. Since there were 8 she got 3 out of the total (8) cupcakes. I used those specific number because that is the most simplified numbers.

Answer:

A total of 78,497 pounds of cargo was removed from the plane.

Step-by-step explanation:

I got my answer by subtracting 437,981 from 500,000 to get 62,019. After, I added the additional 16,478 pounds that were taken off after to get my total of 78,497. My answer is reasonable because after double-checking with my calculator, I noticed I did not make any mistakes and my answer checked out, therefore validifying my answer. Hope this helps and have a good rest of your day/ night :)

Step-by-step explanation:

y - 3 = 2x+4

y = 2x+4+3

y = 2x+7

Answer:

18

Step-by-step explanation:

3 (x - 4) - 16 = 2 (x - 8 ) + 6

=> 3x - 12 -16 = 2x - 16 + 6

=> 3x - 28 = 2x - 10

=> 3x - 28 - 2x = -10

=> x = 18

Answer:

18

Step-by-step explanation:

3(x - 4) - 16 = 2(x - 8) + 6

(3x - 12) - 16 = (2x - 16) + 6 (multiply 3 with (x-4) , and 2 with (x-8))

3x - 28 = 2x - 10 (subtract the numbers,remember only the same qualities)(meaning we leave out 3x and 2x)

3x - 2x = -10 + 28 (move 2x to the left(becomes negative(minus)) and move -28 to the right(becomes positive)(do your calculations)

x = 18 (final answer)

Answer:  see proof below

Step-by-step explanation:

Given: cos 330 = [tex]\frac{\sqrt3}{2}[/tex]

Use the Double-Angle Identity: cos 2A = 2 cos² A - 1

[tex]\text{Scratchwork:}\quad \bigg(\dfrac{\sqrt3 + 2}{2\sqrt2}\bigg)^2 = \dfrac{2\sqrt3 + 4}{8}[/tex]

Proof LHS → RHS:

LHS                          cos 165

Double-Angle:        cos (2 · 165) = 2 cos² 165 - 1

                             ⇒ cos 330 = 2 cos² 165 - 1

                             ⇒ 2 cos² 165  = cos 330 + 1

Given:                        [tex]2 \cos^2 165 = \dfrac{\sqrt3}{2} + 1[/tex]

                              [tex]\rightarrow 2 \cos^2 165 = \dfrac{\sqrt3}{2} + \dfrac{2}{2}[/tex]

Divide by 2:               [tex]\cos^2 165 = \dfrac{\sqrt3+2}{4}[/tex]

                             [tex]\rightarrow \cos^2 165 = \bigg(\dfrac{2}{2}\bigg)\dfrac{\sqrt3+2}{4}[/tex]

                             [tex]\rightarrow \cos^2 165 = \dfrac{2\sqrt3+4}{8}[/tex]

Square root:             [tex]\sqrt{\cos^2 165} = \sqrt{\dfrac{4+2\sqrt3}{8}}[/tex]

Scratchwork:            [tex]\cos^2 165 = \bigg(\dfrac{\sqrt3+1}{2\sqrt2}\bigg)^2[/tex]

                             [tex]\rightarrow \cos 165 = \pm \dfrac{\sqrt3+1}{2\sqrt2}[/tex]

             Since cos 165 is in the 2nd Quadrant, the sign is NEGATIVE

                             [tex]\rightarrow \cos 165 = - \dfrac{\sqrt3+1}{2\sqrt2}[/tex]

LHS = RHS [tex]\checkmark[/tex]

Step-by-step explanation:

Answer:

(-32, 0)

Step-by-step explanation:

The x-intercept is the point on the line whose y-coordinate is zero.

Look at the points (8, 28) and (-2, 21).

As y goes from 28 to 21, a difference of 7, x goes from 8 to -2, a difference of 10.

Now look at the points (-2, 21) and (12, 14).

As y goes from 21 to 14, a difference of 7, x goes from -2 to -12, a difference of 10.

As you can see, each time y goes down by 7, x goes down by 10.

Start with (-12, 14).

Subtract 7 from y and 10 from x to get (-22, 7).

Now start with (-22, 7). Subtract again 7 from y and 10 from x.

You get (-32, 0).

Since now you have a y-coordinate of 0, point (-32, 0) is the x-intercept.

Answer: (-32, 0)

Answer:

  see attached

Step-by-step explanation:

Translation 12 units down puts each point 12 units lower on the graph than the position where it is currently shown. Segment RS is now shown on the line y=9. It will be translated straight down so it appears on the line y = 9-12 = -3.

Similarly, T has a y-coordinate of 2. Translated down 12, it will have a y-coordinate of y = 2-12 = -10.

The x-coordinates of all of the points remain the same.

The translation is shown in the attachment.

6 games, assuming shoe rental only has to be paid one time.

Answer:

The answer is B.

Step-by-step explanation:

Given that vertically opposite angles are the same so the inner angle of the triangle is 40°.

Next, you have to find the other angle of the triangle. Assuming that total angles in a triangle is 180° so you have to subtract :

180° - 40° - 90° = 50°

So the value of x is 50°.

Answer:

2

Step-by-step explanation:

use slope equation

Answer:

x = 7

Step-by-step explanation:

Since the two sides (9x - 25) of the triangle are congruent to each other, we can add them together

(9x - 25) + (9x - 25)

18x - 50

A triangle is 180 degrees when adding all three sides

So if 2 sides together equal 18x - 50 and the last side equals 104, then they should equal 180 total

18x - 50 + 104 = 180

Combine like terms

18x + 54 = 180

Subtract both sides by 54 to isolate the variable

18x + 54 - 54 = 180 - 54

18x = 126

Divide both sides by 18 to isolate the variable

18x ÷ 18 = 126 ÷ 18

x = 7

Check your work by plugging in the x value for the expression and adding all three sides to equal 180 degrees

9(7) - 25 + 9(7) - 25 + 104 = 180

Pemdas says to multiply first

63 - 25 + 63 - 25 + 104 = 180

38 + 38 + 104 = 180

76 + 104 = 180

180 = 180

The work is correct
