Answer:
30(2+3)
Step-by-step explanation:
1) Find GCF of 60 and 90 (30)
2) Divide both by GCF
3) Put GCF in front of parentheses, then add quotients within the parentheses
Answer:
2
Step-by-step explanation:
The constant of proportionality in the equation x/y = 2/g is 2. 2 is the only number in the equation.
Answer: D) Reflect over x-axis
=======================================================
Explanation:
When we do this type of reflection, a point like (1,2) moves to (1,-2).
As another example, something like (5,-7) moves to (5,7)
The x coordinate stays the same but the y coordinate flips in sign from positive to negative, or vice versa.
We can say that
as a general way to represent the transformation. Note how y = f(x), so when we make f(x) negative, then we're really making y negative.
If we apply this transformation to every point on f(x), then it will flip the f(x) curve over the horizontal x axis.
There's an example below in the graph. The point A(2,8) moves to B(2,-8) after applying that reflection rule.
