Which statements are true about the ordered pair (5, −6) and the system of equations? {x+y=−13x−y=21 Select ALL correct answers. A. The ordered pair (5, −6) is a solution to the first equation because it makes the first equation true. B. The ordered pair (5, −6) is a solution to the second equation because it makes the second equation true. C. The ordered pair (5, −6) is a solution to the system because it makes both equations true. D. The ordered pair (5, −6) is not a solution to the system because it makes at least one of the equations false.

idk this answer sorry cant on this one.

step-by-step explanation:

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}  

5⋅2  

x

2  

x

​    

=240

=48
