(x,y): y = 2x + 1 y = x/2 + 4

Since y equals both those expressions it is easiest just to say

2x+1 = x/2 +4

then multiply both sides by 2 to get rid of the fraction
and I am hoping you can do it from there.

When you get your answer, plug the numbers back into the original equations to check that they are correct.

Area = (1/4 ) of pi* r ²

plug in the numbers that you know and solve for r.

You can do this yourself

plug in a value for x
then plug in the number that is 1 less for x
And, see what the difference is.

For example you might use 3 then 2
or
1 then 0
or
200 then 199

You will get the same answer whatever numbers you choose.

4x means 4*x
4*x = 20

They are both 5 and a bit so the question is
which is bigger 0.05 or 0.5

0.5 = 5/10

Do you know what the answer is?
