Minchanka [31]2 years ago
6 0

Answer:

<h2>The value of y is <u>0.5</u>, so the answer is <u>C</u>.</h2>

Step-by-step explanation:

Find first the constant of variation.

Given: x = 3, y = 4

Find: k = ?

Formula:

y =  \frac{k}{x}

Solution:

y =  \frac{k}{x}  \\ 4 =  \frac{k}{3}  \\ 12 = k

Then, find the value of y in the third box.

Given: x = 24, k = 12

Find: y = ?

Formula:

y =  \frac{k}{x}

Solution:

y =  \frac{k}{x}  \\ y =   \frac{12}{24} \\ y =  \frac{1}{2} \\\boxed{y = 0.5}

If n is divided by 7 the remainder is 3. What is the remainder if 3n is divided by 7?
Keith_Richards [23]
So, if n Divided by 7 = 3 , then n must be 21, because if you do 3 x 7 it equals 21, so now we know n is 21, then that means its 3 x 21 divided by 7 which is 9. Hope i helped ^-^

Answer:

Growth: 3

y-intercept: 5

Step-by-step explanation:

1. Find the equation in slope-intercept form:

-6x+2y=10

2y=6x+10

y=3x+5

2. Then we can easily identify the growth and y-intercept.

Solve this equation 3(2x+3)=9
Scilla [17]

Answer:

0

Step-by-step explanation:

Isolate the variable x. First, distribute 3 to all terms within the parenthesis.

3(2x + 3) = 3(2x) + 3(3) = 6x + 9

6x + 9 = 9

Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. First, subtract 9 from both sides.

6x + 9 (-9) = 9 (-9)

6x = 0

Divide 6 from both sides.

(6x)/6 = (0)/6

x = 0

0 is your answer.
