Can yall help me pls

The best way to solve these by graphing instead of substitution or elimination, is to use a free website called Desmos. Input the 2 equations and find the intersection.

a) 2 lines intersecting at (4,2)

Step-by-step explanation:

When u graph y=2x, you start at (0,0) and go up two and over one to the right

When you graph y= - 1/2 + 5 you start at 5 and go down one and over two to the right

You can see the intersect

the answer is 62

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

=240
