In the graph below, line k, y = -x makes a 45° angle with the x- and y-axes. Complete the following:

RyRk : (2, 5)

(-5, 2)
(5, -2)
(-5, -2)

three-fourths of an hour

36÷48=0.75

0.75=

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}
