Answer:

Sophia | 318 |  2(318) - 15 | False

George | 417 |  2(417) - 15 | False

Nancy | 310 | 2(310) - 15 | True

Hank | 136 |  2(136) - 15 | False

Paula | 62 | 2(62) - 15 | False

Gavin | 24 |  2(24) - 15 | False

Step-by-step explanation:

With Sophia, her equation is 2(318) - 15. That equals 621, not 605.

With George, his equation is 2(417) - 15. That equals 819, not 605.

With Nancy, her equation is 2(310) - 15. That equals 605.

With Hank, his equation is 2(136) - 15. That equals 257, not 605.

With Paula, her equation is 2(62) - 15. That equals 109, not 605.

With Gavin, his equation is 2(24) - 15. That equals 33, not 605.

=-14x^2+70x

=-14(x^2-5x)

=-14(x-5/2)^2+175/2

the max. height=175/2

What is the slope of the line shown?<br><br> -7/9<br> 9/7<br> 7/9<br> -9/7
SpyIntel [72]

To find slope, we must find the change in y values divided by the change in x values, also called the rise/run. This is modeled below:

Slope = m = (y1 - y2)/(x1-x2) = (6-(-3))/(1 - (-6)) = (6+3)/(1+6) = 9/7

We can check that this answer is correct by consulting the graph. The graph shows a positive correlation (means that the slope should be positive), and if you count the graph unit squares, you get that the graph moves up 9 squares and over 7 squares between the two points shown, letting us know we got the right answer.

Hope this helps!

Crank
If you use the first answer, the equation becomes 2x + 2y = 16.  You could subtract this from equation Q to eliminate x.

The second answer makes equation P -2x - 2y = -16.  You could add this to equation Q to eliminate x.  You can use both of these methods to eliminate the x term, but if you can only choose one, you should choose the second option.

Answer:

<em>XY = 92 units</em>

Step-by-step explanation:

<u>Similar Shapes</u>

Two shapes are similar if all their corresponding side measures are in the same proportion.

The triangles UVW and YVX are similar because their side lengths are in the proportion 1:2, given the tick marks provided in the drawing.

This means that the measure of VX is twice the measure of VW,

The measure of YV is twice the measure of UV

The measure of XY is twice the measure of UW

This last proportion gives the equation:

z + 46 = 2z

Solving for z:

z = 46

Thus, XY = z+46 = 92

XY = 92 units
