Answer: true
Step-by-step explanation: f(x) is a function because each x value (left oval) has one y value (right oval)!
For this case we have that by definition, the Greatest Common Factor or GFC of two or more numbers, is the largest number that divides them without leaving residue.
So, we have to:
We look for the factors of 18 and 36:
18: 1,2,3,6,9,18
36: 1, 2,3,4, 6,9,18 ...
It is observed that the GFC of both numbers is 18.
Then, the GFC of
and
is:
18x
Answer:
18x
The equivalent 90° CCW rotation maps (x, y) to (-y, x).
(4, -2) becomes (2, 4) after rotation.
Answer:
4
Step-by-step explanation:
5 x 4 = 20
+ 12 = 32
