D. 9 + y = 6x and 6x - y = 9 has an infinite number
of solutions.
True
False

True

Step-by-step explanation:

9 + y = 6x -> y = 6x - 9

6x - y = 9 -> y = 6x - 9

A solution occurs whenever there is a value for x that can solve both equations.

The equations are the same.

If you plotted them on a graph they would overlap and there would be a straight diagonal line going on forever.

So there are infinitely many solutions.

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
