A researcher surveyed 8 people to see if there is a relationship between years of education and starting salaries. The data points are shown on the graph. Which best represents the equation of the trend line shown on the graph? (Note that the graph has a break on the x-axis.)
y = 0.25x + 15
y = 0.25x + 17.5
y = 1.25x – 10
y = 1.25x + 7.5

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
