The midpoint of CD is M=(5. –1). One endpoint is C=(7.1). Find the coordinates of the other endpoint, D.

D = (3, -3)

Step-by-step explanation:

A key fact needed to solve this is that the distance of C to M is equal to the distance of D to M, as M is the midpoint of CD. Now considering the x and y distance of C to M separately, C is 2 to the right (7 - 5) and 2 up from (1 - -1) M. This means that, conversely, D has to be 2 to the left and 2 down from M. Doing the maths, we see that (5 - 2, -1 - 2) = (3, -3).

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
