7 0

Answer:

C. x=-2

Step-by-step explanation:

To solve use PEMDAS,

First, distribute

6-x=20+4x-4

Then, combine like terms

6-x=16+4x

Add x to both sides

6=16+5x

Subtract 16 from both sides

-10=5x

Divide both sides by 5

-2=x

Questions 1-3 you have to multiply the whole number that many times of that power that is given.
Question 1. 2 x 2 x 2 x 2 =16
Question 2. 3 x 3 x 3 = 27
Question 3. 10 x 10 =100
Question 4. Braces
Question 5. 4+3 x 5 First you are going to multiply 3 x 5 =15. Second you add 15 + 4 = 19. Answer = 19. First you perform multiplying.
Question 6. You first add the 9+7=16 then divided that by 2 and you get 8. First you perform addition.
Question 7. First you have to do parentheses 12+6 =18 then divided 18 by 6 and you get 3. First you perform the parentheses.
Question 8. 8(11-6) First you subtract what is in the parentheses and you get 5 then you multiply 8 x 5 = 40. The last thing you perform in the multiplying.
Question 9. First you do the exponents. 4 x 4 =16 then 16 + 3 =19. The last thing you perform in the addition. Answer 19.
Question 10. First Subtract 5-3= 2 then you do 10 divided by 2 = 5. The last thing you perform is dividing. Answer 5.
Question 11. 8+7 x 4 First you multiply 7 and 4 = 28 then 28 + 8 = 36. Answer 36.
Question 12. 10-3+6-2 =7+6-2=13-2=11. Answer 11.
Question 13. 6+8 divided by 2. First add 6+8=14 divided by 2 = 7. Answer 7.
Question 14. You would have to do the distributive property. 6 x 14 = 84. Then multiply 6 x 1 = 6. Then subtract 84-6 =78. Answer 78.
Question 15. First subtract 6-2=3. Then do 3 x 3 =9. Next add 1 +7 =8. Then multiply 9 x 8 = 72. Answer 72.
Question 16. First subtract 18-6=12. Then 12 divided by 3 = 4. Answer 4.
Question 17.First you do exponents 3 x 3 = 9. Then add 16 + 9 = 25. Answer 25.
Question 18. First you do exponents 6 x 6 = 36. Then subtract 40 - 36 =4. Next add 4 + 7 = 11. Answer 11.
Question 19. First you do exponents 2 x 2 = 4. Then divided 24 by 4 = 6. Answer 6.
Question 20. First you do exponents 10 x 10 x 10 = 1000. 10 x 10 =100. 10 x 1 = 10. Next step is to multiply. 5 x 1000 = 5000 and multiply 3 x 10 = 30. Then the rest is addition. 5000+ 8+100+30+7 =5145. Answer 5145.

Find the indicated side length.

Schach [20]

Answer: KL = 5.3

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

Set up the proportion, cross multiply, and solve for the missing side:

$\frac{JL}{GL} = \frac{KL}{HL}$

$\frac{4}{10} = \frac{KL}{8 + KL}$

4(8 + KL) = 10(KL)

32 + 4KL = 10KL

32 = 6KL

$\frac{32}{6}=KL$

KL = 16/3 = 5.3

A rubber ball has a radius of about 2.86 in. Can the ball be packaged in a box shaped like a cube with a volume of 125 in3?

Vlada [557]

Answer:

I am not sure what the values needed to add in / etc, but here is the height of the box: 5

Step-by-step explanation:

A cube is a kind of rectangle where all the sides are the same. So to find volume, cube the length of any side. To find height, calculate the cube root of a cube's volume. For this example, the cube has a volume of 125. The cube root of 125 is 5. The height of the cube is 5.

(hopefully this is correct, have a nice day!)

The function f(x) = One-sixth (two-fifths) Superscript x is reflected across the y-axis to create the function g(x). Which order

Gekata [30.6K]

The ordered pair (-3 , $\frac{4}{375}$ ) is on g(x) ⇒ 1st answer

Step-by-step explanation:

Let us revise the reflection across the axes

If the function f(x) reflected across the x-axis, then its image is g(x) = - f(x) (change the sign of y)
If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x) (change the sign of x)

∵ $f(x)=\frac{1}{6}(\frac{2}{5})^{x}$

∵ f(x) is reflected across the y-axis to create the function g(x)

- Change the sign of x

∴ $g(x)=\frac{1}{6}(\frac{2}{5})^{-x}$

To find the point that lies on g(x) substitute x in g(x) by the x-coordinate of the point if the answer equal to the y-coordinate of the point, then the point lies on it if not then the point does not lie on it

∵ The coordinates of the point are (-3 , $\frac{4}{375}$ )

∴ x = -3 and y = $\frac{4}{375}$

- Substitute x by -3 in g(x)

∵ $g(x)=\frac{1}{6}(\frac{2}{5})^{-x}$

∴ $g(x)=\frac{1}{6}(\frac{2}{5})^{-(-3)}$
