X - y = 9
x + 2y = 27
You can subtract the top equation from the bottom
3y = 18
y = 6
x = 15
The two numbers are 15 and 6
Answer:
x+2y-14=0
Step-by-step explanation:
Divide both sides of equation by 3
This is the answer y= -x+3
Another way to ask this question: where the x-value of function g equals 12, what's the y-value?
remember that function notation is like so: f(x), g(x), h(x)... so the number in the parentheses is an x-value from the function.
look through your points and find the one that represents an x-value of 12. (12, 19) is the point, and 19 is your output--so, g(12) = 19.
Answer:
a difference of squares
Step-by-step explanation:
Let's write down the expression:
we can see that this expression is one of the form 
which is the general expression of a difference of squares.
To be more specific and to see why we say this, let's make 
and 
Now, if we substitute this in the general formula, we get:
Thus, this expression is a difference of squares.
