What is -5/9 = -10/3 v
Brut [27]

Answer:

v= 1/6

Step-by-step explanation:

1. Simiplify 10/3v = 10/3v -5/9= -10v/3

2. Multiply both sides by 3

3. Use this rule : a/b × c = ac/b

4. 5× 3= 15 -15/9= -10v

5. Simiplify 15/9 = 5/3 -5/3 = -10v

6. Divide both side by -10 -5/3/-10=v

7. Two negative make a postive 5/3/10 = v

8. Simplify 5/3/10= 5/3×10

9. Simplify 3×10=30 5/30=v

10. Simplify 5/30 = 1/6v

11. Swith sides v= 1/6

Your answer is 150.72.

First, plug in the radius and height into the equation. V=1/3pi*4^2*9
Next solve. 3.14 x 16 x 9 = 452.16
Then you need to divide 452.16 by 3 to get 150.72

This is function notation and I have no idea how to do it. I need answers.
pashok25 [27]

Answer:

So you are given the function, f(x) = 3x - 4. You will plug in the value given and solve and write the answer down in the box.

f(x) = 3x - 4 ---> f(5), f(2), f(1), f(10), and f(-1) value given

f(5) = <u>3(5)</u> - 4

f(5) = <u>15 - 4</u>

f(5) = 11

f(2) = <u>3(2)</u> - 4

f(2) = <u>6 - 4</u>

f(2) = 2

f(1) = <u>3(1)</u> - 4

f(1) = <u>3 - 4</u>

f(1) = -1

f(10) = <u>3(10)</u> - 4

f(10) = <u>30 - 4</u>

f(10) = 26

f(-1) = <u>3(-1)</u> - 4

f(-1) = <u>-3 - 4</u>

f(-1) = -7

Step 2. Four times the number and 5 is divided by 3

Step 3. The result is 16

Step 4. Multiply by 3 to both sides of equation to get rid of denominator

Step 5. Subtract 20 from both sides of equation

Step 6. Divide by 4 to both sides of equation
