The endpoints of CD are C(–8, 4) and D(6, –6). What are the coordinates of point P on CD such that P is the length of the line s
GalinKa [24]
If you graph the end points C and D then graph the 4 points at the end it is difficult to tell which points are on CD without a line.  
Using the endpoints find the slope (change in y/ change in x) then substitute a point in to find the intercept.  
Slope = (-6-4)/(6- -8) = -5/7
Intercept equation (-6) = -5/7 (6) + b
b = -1.71428571429
Graphing the line shows only 2 points on the line (–2.75, 0.25) and <span>(0.75, –2.25)
I am confused by the part, "</span><span>P is the length of the line segment from D".  Were you given a length P to help you determine which point.  Using the distance formula to find the length from each point to D doesn't help determine which one is best with the information you have given.  The image shows the distances I calculated and the graphed points. 
I hope this helps!</span>

The lengths of the bases of a trapezoid are 17 inches and 10 inches. The trapezoid has an area of 189 square inches.
Mamont248 [21]

Answer:

height of this trapezoid is 14 inches.

Step-by-step explanation:

\boxed{Area -of -trapezoid=\frac{a+b}{2} h}

[ Here lengths, a = 17 and b = 10 and area of trapezium given 189 ]

using the formula:

\frac{17+10}{2} *h = 189

\frac{27}{2} h = 189

h = \frac{189*2}{27}

h  =14

Viefleur [7K]

Answer:

(5,-3) is a solution of -x-y=-2

Step-by-step explanation:

You just plug in the numbers in the equation

x=5 y=-3

-5(5)+2(-3)=-25-6 which doesn't equal -21

-5-(-3)=-5+3=-2

What is the value of x
slega [8]

Answer:

54

Step-by-step explanation:

A tangent line makes a right angle with the radius to the point of tangency. Hence this triangle is a right triangle, and x° is the complement of 36°:

x° = 90° -36° = 54°

The value of x is 54.
