A student used the slope-intercept form to write the equation of a line that has a slope of -2 and passes through the point (StartFraction negative 3 Over 10 EndFraction, 5). The student’s work is shown to the left. Analyze the steps to identify the error.

Step1: student switched the x and y values

Step 3: student needed to add StartFraction 6 Over 10 EndFraction to both sides

Step 5: student subtracted incorrectly

Step 6: student needed to add the b value

answer: i don't understand it

step-by-step explanation: sorry

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

x

=240

=48
