Answer:

<h3>Nira's present age= 30</h3>

Step-by-step explanation:

$her \: age \: before \: 10years \: = x - 10 \\ her \: age \: after \: 10years \: = x + 10 \\ therefore.(x - 10) + (x + 10) = 60 \\ x - 10 + x + 10 = 60 \\ 2x = 60 \\ x = 60 \div 2 \\ x = 30 \\ hope \: it \: helps....$

Answer:

I think Nira would be 30 years old

Step-by-step explanation:

So 10 years before and after her present age added together equals 60. So if she was 30, it would be 20+40 which =60.

Two students in your class, Tucker and Karly, are disputing a function. Tucker says that for the function, between x = –3 and x

Effectus [21]

The difference between Tucker and Karly's take is that Tucker's solution is analytical while Karly's is graphical. But both are correct either way.

For Tucker's solution, let's say at x=-3 the value for y is 4, and at x=3, the value of y is still 4, then the average rate of change or slope is 0. Note that the slope of the curve is Δy/Δx. Since there is no change for Δy, the slope is zero.

For Karly's solution, even if the curve travels high or low but would have the same elevation of x=-3 and x=3, the average rate of change is still zero. It is actually just same with Tucker's but Karly just verbalizes her solution that was observed visually.
