What are Factors and Primes?

1 answer:

3 0

A factor of a number is a number you multiply by another factor to get a number. For example, a factor of 6 is 3 because 3 × 2 = 6, and a factor of 12 is 4 because 4 × 3 = 12. A prime number is a number that only has two factors, 1 and itself, which every number has. Examples of prime numbers are 13, 5, 47, 93, etc. Let me know if you still don't get it!

Answer:

$f^{-1}(x)=25(x-2)^2$

Step-by-step explanation:

The inverse function can be found by solving ...

f(y) = x

(√y)/5 +2 = x

(√y)/5 = x -2 . . . . . subtract 2

√y = 5(x -2) . . . . . . multiply by 5

y = 25(x -2)² . . . . . square both sides

The inverse function is ...

$f^{-1}(x)=25(x-2)^2$

Solution q-2r=4<br> q+r=37

GenaCL600 [577]

Q-2r=4, therefore: q=4+2r.

Plug the value of q into q+r=37, so you get:

4+2r+r=37

3r=37-4=33

3r=33

Therefore: r=11.

q-2r=4, but r=11, so:

q-2(11)=4

q-22=4

Therefore q=26.

Check if the answer is correct using second equation:

q=4+2r=4+2(11)=4+22=26.

So: q=26 and r=11.
