Answer:

<h2>x = 9</h2>

Step-by-step explanation:

\frac{x}{3}  =  \frac{2x + 3}{7}

<u>Cross multiply</u>

That's

7x = 3( 2x + 3)

Multiply the terms

That's

7x = 6x + 9

<u>Subtract 6x from both sides</u>

We have

7x - 6x = 6x - 6x + 9

Simplify

We have the final answer as

<h3>x = 9</h3>

Hope this helps you

Question #3: Complete the statement below to show the correct value of 100%. Part A: The expression 100 3 = 10 because 100 = 102
BigorU [14]

Answer:

Step-by-step explanation:

Part A.

Expression (100)^{\frac{1}{2}} = 10

Because 100 = (10)^{2} and [(10)^2]^{\frac{1}{2}}=10^1=10

[Since, (a^{2})^{\frac{1}{2}}=a^{2\times \frac{1}{2}}=a^1]

Part B.

When simplified, the answer is RATIONAL.

[Since, 10 can be written as \frac{10}{1}]

Which function is represented by the graph?
solong [7]

Answer:

f(x) = |x + 1| – 3

Step-by-step explanation:

The given graph is a transformed absolute value function.

The parent function is

g(x) =  |x|

The graph is obtained by shifting, g(x) from the origin (0,0) to (-1,-3).

The transformed function is of the form:

f(x) =  |x - h|  + k

Where (h,k) is the vertex.

We substitute h=-1 and k=-3 to get:

f(x) =  |x -  - 1|  +  - 3

When we simplify we get:

f(x) =  |x  + 1|  - 3

What is the volume of the cone shown below?
kipiarov [429]

Volume = PI x r*2 x h/3

r = radius which is shown as 8

h is the height which is shown as 63

Volume = 3.14 x 8^2 x 63/3

Volume = 3.14 x 64 x 21

Volume = 4,220.16 cubic units.
