You have solved a radical equation. What should you do to check whether your proposed solution is​ correct?

You should check your proposed solution in any of the equations you found while looking for the solution.

You​ don't need to check whether your proposed solution is correct. You know you followed the proper​ method, so it should be fine.

You should check the proposed solution in the original equation.

You should check the proposed solution in the back of the book because it is always right.

Answer:

Step-by-step explanation:

1) 2^2 + 2^2 = c^2

4 + 4 = c^2

8 = c^2

c = sqrt8

2) 2^2 + 3^2 = c^2

4 + 9 = c^2

13 = c^2

c = sqrt13

3) 10^2 + 4^2 = c^2

100 + 8 = c^2

108 = c^2

c = sqrt108

4) 1^2 + 5^2 = c^2

1 + 25 = c^2

26 = c^2

c = sqrt26

5) 3^2 + 1^2 = c^2

9 + 1 = c^2

10 = c^2

c = sqrt 10

6) 9^2 + 9^2 = c^2

81 + 81 = c^2

162 = c^2

c = sqrt162

slope is the change in y over the change in x.

Using the first and last values:

Slope = (8 - -4)/ (2 - -2)

Slope = 12/4

Slope = 3

Answer:

30 students

Step-by-step explanation:

you have a ratio, and an unknown amount, so set up a proportion

[tex]\frac{2}{3} = \frac{x}{18}[/tex] I used x because the amount of boys is unknown

so then, cross multiply

(so do 3 times x, and 2 times 18)

[tex]3x=36[/tex]

then divide both sides by 3 to get x by itself, and you get

[tex]x=12[/tex]

this means there are 12 boys in the class. because the problem is asking for the total number of students, add 12 and 18 (the number of boys and girls).

you get 30, so there are 30 students in her class.

Answer:

121 minutes

Step-by-step explanation:

First, we divide the time by the miles

22 ÷ 2 = 11

So now that we have the unit rate, 1 mile for every 11 minutes, we can multiply 11 (the unit rate minutes) by 11 (the given miles she wants to reach)

11 x 11 = 121

So, in 121 minutes, Wendy can walk 11 miles.

(the double number line will look something like this, but going all the way until 121:11)

Answer:

[tex]m=\frac{1}{2}[/tex]

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply plug in 2 coordinates into the slope formula to find slope m:

(0, 2)

(-4, 0)

[tex]m=\frac{2-0}{0-(-4)}[/tex]

[tex]m=\frac{2}{0+4}[/tex]

[tex]m=\frac{2}{4}[/tex]

[tex]m=\frac{1}{2}[/tex]

Answer: 30

Step-by-step explanation:

24 + f = 54

f = 54 - 24

f = 30

Answer:

f=30

Step-by-step explanation:

You want to get x by itself on one side, so in order to do that, you need to subtract the 24, and if you do it one side, you need to do it to the other side.

That would give you:

24-24+f=54-24

then simplify it to be:

f=30

Answer:

0, π, 2π, π/6 and 5+(π/6)

Step-by-step explanation:

Rearranging, sinx (2 sinx - 1) = 0.

In [0, 2π],sin x = 0 for x = 0, π and 2π.

The other factor = 0 gives the other two solutions.

sin 5+(π/6) = sin (π−(π-6)) = sin π/6 = 1/2.

Answer:

parallel: m= -1/5

parpendicular: m= 5

Step-by-step explanation:

parallel lines have the same slope

- 1      stays the same so      - 1  

 5                                            5

parpendicular lines have the opposite reciprocal slope

- 1      flipped is     - 5      turn the negative into a positive   5      or    5

 5                             1                                                                  1

Answer:

B is correct: (-sqrt15)/8

Step-by-step explanation:

The value of the x is 104.5° then the value of the sin 2x is -0.49. Then the correct option is B.

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

If cos(x) = -1/4 and tan(x) < 0

Then the value of the x will be

[tex]\begin{aligned} \cos x &= - \dfrac{1}{4}\\\\x &= \cos^{-1} \dfrac{-1}{4}\\\\x &= 104.5^o \end{aligned}[/tex]

Then the value of the sin 2x will be

[tex]\sin 2x = \sin 2*104.5^o\\\\\sin 2x = \sin 209^o\\\\\sin 2x = -0.4848 \approx 0.49[/tex]
