We can automatically see that we are dealing with a percent decrease because we are going from a smaller to a bigger number. We need to first find what percent of 140the number 84 is. to do this we can set up the following equation:

140/84=100/x (this equation is basically saying if 140 is 100(%) what would 84 be?)

solving for x here gives us x = (84 X 100)/140 = 60, so 84 is 60 percent of 140 which means 140 decreased by 40 percent.

Let me know if I can clear anything else up.

Find the rate of change: Mike can bike 3 miles in an hour. What is the speed at which mike can bike?
masya89 [10]
Rate  of  change=<span><span>change  in  y divided by </span><span>change  in  <span>x
y= 3,6,9
x= 1,2,3
The numbers chosen above are because if mike travels 3 miles in one hours then he can travel 6 miles in two hours and 9 miles in 3 hours. 
Change in y = 3
Change in x = 1
3 / 1 = 3
So, the rate of change is 3.</span></span></span>

Which equation describes the function?<br><br><br> Will give brainliest
Natalija [7]

Answer:

y = - \frac{7}{3} x  + 4

Step-by-step explanation:

I'm going to use the process of elimination to get rid of the equations. The equation for slope is y=mx+b with b being the y-intercept. As you can see the y-intercept in this graph is 4 which removes the third equation as a possible answer. The slope is moving from left to right in a downwards direction which means it is a negative slope. The only answer with a negative slope is b therfore it is your answer.
