I believe the correct answer from the choices listed above is the first option. The statement that best explains the graph that shown below would be yes, the points shown on the line would be part of y = 0.5x. Hope this answers the question. Have a nice day.

The <u>correct answer</u> is:

<span>A) Yes, the points shown on the line would be part of y = 0.5x.

Explanation:

Looking at the graph, the line goes through (0, 0).  If x=0, we have
y=0.5(0)=0.  
This is the y-coordinate of the point, so it goes through this.

The equation for this line is in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept.  In this equation, m=0.5 and b=0.  This means the slope is 0.5 or 1/2; since slope is rise/run, this means the line rises 1 for every horizontal increase of 2.  

This means starting from (0, 0), we would go up 1 and over 2, creating the point (2, 1).  Looking at the graph, the line goes through this point.

Next we would go up 1 and over 2 again, to (4, 2).  Again, the line goes through this point.

We could follow all of the points on this line and they all fit.</span>

the length of a rectangle is 2 inches less than 3 times it width . The perimeter of the rectangle is 124 inch. WHat is the lengt
vitfil [10]

Step-by-step explanation:

let w = width

length = 3w-2

perimeter = 2*length + 2*width

perimeter = 2(3w-2) + 2w

perimeter = 6w - 4 + 2w

perimeter = 8w - 4

perimeter = 124 inch

8w - 4 = 124inch

<em>+4 to each side</em>

8w = 128inch

<em>divide each side by 8</em>

w = 16

length = 3w-2

           = 3(16) - 2

length = 46 inch

Mario’s company makes unusually shaped imitation gemstones. One gemstone has 14 faces and 10 vertices. How many edges does the g
Ivan
The gemstone has 22 edges.

We use Euler's formula on this:

F + V - E = 2

Substituting our information, we have:

14 + 10 - E = 2

Combining like terms, 
24 - E = 2

Subtract 24 from both sides:
24 - E - 24 = 2 - 24
-E = -22

Divide both sides by -1:
-E/-1 = -22/-1
E = 22

80% of what number is 64
Thepotemich [5.8K]
Make an equation.

80% = 0.8

'of' is multiplication

'what number' is 'x'

'is' is an equal sign

0.8 * x = 64

0.8x = 64

Divide 0.8 to both sides:

x = 80
