Sergeu [11.5K]3 years ago
8 0

Step-by-step explanation:

10 - <em>3x</em><em> </em><em>=</em> x-4

Collect like terms

10 +4 = x + 3x

14 = 4x

Divide both sides by 4

<em>X</em><em> </em><em>=</em><em> </em><u>14</u>

4

= <u>7</u>

2

= 6 <u>1</u>

2

Or

= 6.5

- Does the graph below represent a function? How do you know? please answer! ​
andrezito [222]

Answer:

No, the graph does not represent a function because it does not pass the vertical line test.

<h2>What is a function?</h2>

A function is when each x-value only has one y-value. We know that a graph represents a function if it passes the vertical line test.

<h3>Vertical Line Test</h3>

To pass the test, any vertical line that we draw on the graph should only touch one point.

A vertical line is a straight line that goes from top to bottom.

  1. Draw vertical lines through points on the graph, like in the photo below.
  2. Check if any vertical lines touch more than one point.

The yellow vertical line touches two points, which is more than one. So, the graph does not pass the test. This graph is does not represent a function.

1.what is the volume of the small cone in terms of pi
svp [43]

Step-by-step explanation:

<u>Step 1:  Find the radius of the big cone</u>

\frac{radius_1}{height_1} = \frac{radius_2}{height_2}

\frac{2}{5}=\frac{x}{10}

2(10)=5(x)

20/ 5=5x / 5

4=x

<u>Step 2:  Find the volume of the small cone</u>

V = \frac{\pi*r^2*h} {3}

V = \frac{\pi * 2^2 * 5}{3}

V = \frac{20\pi}{3}\  units^3 ← Volume of Small Cone

<u>Step 3:  Find the volume of the large cone</u>

<u />V = \frac{\pi*r^2*h} {3}

V=\frac{\pi*4^2*10}{3}

V = \frac{160\pi}{3}\  units^3 ← Volume of Large Cone

A prism is completely filled with 2304 cubes that have edge length of 1/4 cm what is the volume of the prism
Tomtit [17]

Since the prism completely filled with 2304 cubs

Since the edge of the cube is 1/4 cm

Since the volume of the cube = edge x edge x edge

Then find the volume of 1 cube, then multiply it by the number of cubes to find the volume of the prism

V_c=\frac{1}{4}\times\frac{1}{4}\times\frac{1}{4}=\frac{1}{64}cm^3

Multiply it by 2304

V_P=2304\times\frac{1}{64}=36cm^3

The volume of the prism is 36 cm^3
