If we were to plot the points on a graph, we could draw a straight lint between them. The question wants us to find the length of this line. We could make a right triangle with this line as the hypotenuse, with an x length of 2(y2-y1) and a y length of 5 (y2-y1). From there we can find the hypotenuse with Pythagorean Theorem: c^2=a^2+b^2. 
c^2=(2)^2+(5)^2
c^2=4+25
C^2=41
c=\sqrt{41}
Decimal approximation: 6.403

Hope this helps!

13. What is the surface area of the rectangular solid below using its net?
loris [4]

<u><em>Answer:</em></u>

108 square units

<h3><u><em>Step-by-step explanation:</em></u></h3>

3 x 4 = 12

3 x 4 = 12

6 x 3 = 18

6 x 3 = 18

6 x 4 = 24

6 x 4 = 24

24(2) + 18(2) + 12(2) = 108 square units

Therefore, the surface area of the rectangular solid below using its net is <u>108 square units</u>

The equation of the line goes through the points (0,5) and (10,0) expain what these points represents in the context of the situ
tamaranim1 [39]

Answer:

The equation would be y = -1/2x + 5

Step-by-step explanation:

To find the equation, we first need to use the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (5 - 0)/(0 - 10)

m = 5/-10

m = -1/2

Now that we have that, we can use that and a point to find the full equation.

y - y1 = m(x - x1)

y - 0 = -1/2(x - 10)

y = -1/2x + 5
