Answer:

The choose (D)

Step-by-step explanation:

\frac{x - 16}{ {x}^{2} + 6x - 40 }  +  \frac{1}{x + 10}  \\  =  \frac{x - 16}{(x - 4)(x + 10)}  +  \frac{1}{x + 10}  \\   = \frac{(x - 16) + (x - 4)}{(x + 10)(x - 4)}  \\  =  \frac{2x - 20}{(x + 10)(x - 4)}  \\   = \frac{2x - 20}{ {x}^{2} + 6x - 40 }

What is the distance between points (5, 13)
horrorfan [7]

You are going to treat this as a triangle so one side is 13 units long and the other is 22. And using the pythagorean theorem a²+b²=c².

13²+22²=c²

169+484=c²

653=c²

√653=√c²

25.55386...=c

Or, rounded to the nearest hundredth, 25.55

Enter the ordered pair for the vertices for Rx-axis(QRST).
mash [69]

Given:

The vertices of a polygon QRST are T(-2, 3), Q(1, 5), R(3, -1) and S(0, 0).

To find:

The vertices for R_{x-axis}(QRST).

Solution:

The rule R_{x-axis}(QRST) represents refection of polygon QRST across the x-axis.

If a figure is reflected across the x-axis, then

(x,y)\to (x,-y)

Using this rule, we get

T(-2,3)\to T'(-2,-3)

Q(1,5)\to Q'(1,-5)

R(3,-1)\to R'(3,1)

S(0,0)\to S'(0,0)

Therefore, the vertices for R_{x-axis}(QRST) are T'(-2, -3), Q'(1, -5), R'(3, 1) and S'(0, 0).
