<u>Answer:</u>

The answer would be D because both ordered pair that was substituted in the equation didn't equal to each other.

<u>Explanation:</u>

All you do is substitute the x and y numbers. (x,y)

<u>A:</u>

Substitute the x and y number

7(2) - 5 = 4(4) - 6

Multiply the number in the parentheses by the outside number on both sides.

14 - 5 = 16 - 6

Subtract both sides to get your solution.

9 = 10

Doesn't equal so that means it's not the solution.

<u>B:</u>

Substitute

7(3) - 5 = 4(6) - 6

Multiply the number in the parentheses by the outside number on both sides.

21 - 5 = 24 - 6

Subtract both sides to get your solution.

16 = 18

It also doesn't equal so that means that it's not the solution either.

<u>C:</u>

Both ordered pair didn't equal to each other so this is not the answer.

Hope this helps!

I have this question about volume of spheres, can you help me out ?
monitta

Given:

The diameter of the sphere = 42 cm

To find the volume of the given sphere.

Formula:

The volume of a sphere is given by V=\frac{4}{3} \pi r^3

The radius is given by r=\frac{d}{2}=\frac{42}{2}=21

<u>Volume of the sphere:</u>

The volume of the sphere is given by

V=\frac{4}{3} (3.14)(21)^3

Simplifying, we get;

V=\frac{4}{3}(3.14)(9261)

Multiplying the terms, we have;

V=\frac{116318.16}{3}

Dividing, we get;

V=38772.7

Thus, the volume of the sphere is 38772.7 cubic cm.

Answer:

Step-by-step explanation:

3x - 4y = 13 (1)

2x + y = 5 (2)

——————

3x - 4y = 13

4(2x + y = 5) (2) times 4

——————-

3x - 4y = 13

8x + 4y = 20

——————-

11x = 33

x = 33/11

x = 3

Plug x = 3 in (2):

2(3) + y = 5

6 + y = 5

y = 5-6

y = -1

Thus, x = 3 and y = -1
