The table below follows the rule y=kx, where k is the constant of proportionality. what is the value of k? table is: × over y 3 over 12 4 over 16 5 over 20 6 over 24 7 over 28

x=4y

Step-by-step explanation:as you can see x is 4 times more than y.

the answer is 8

step-by-step explanation:

3.14 x 8x8

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
