Answer:
Step-by-step explanation:
since 3 * 15 = 45, we know that we have to multiply 5 by 15. so the ratio would be 45:75. I hope this helps!

Given that:

To find:
Difference quotient = ?
where 
Solution:
Formula for Difference quotient is given as:

First of all, let us find out 
Replacing
with 

Now,

Putting the above value in:

We are given that, 

So, the difference quotient is 4.
Answer:
Check the explanation.
Step-by-step explanation:
As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.
As the slop-intercept form is given by:

where m is the slope and b is the y-intercept.
substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.






And the equation of the line in the slope-intercept form will be:

putting b = -5 and slope = m = 5/2



Determining the zero of function.
As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.
so let us determine the value of x (zero of function) by setting y = 0.





Therefore, the zeros of the function will be:
That's no math so you don't need an answer
Answer:
5 miles per hour.
Step-by-step explanation:
Average speed = distance time = 6 / (1 1/5)
= 6 / 6/5
= 6 * 5/6
= 5 miles per hour.
