Mathematics

Answer:

The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation.

So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation. And since x + y = 8, you are adding the same value to each side of the first equation.

F(x)=-3(x-3)^2+12 where is f of x increasing
Schach [20]

Answer: f(x) increases:(x less than or equal to sign 3)

Step-by-step explanation:

Since your equation is in vertex formula, it is more simple to find the vertex first and then go from there.

Since you have in the parenthesis (x-3) and you have the +12 on the outside, we can conclude that the vertex is (3,12) and that it is faces down because of the negative symbol in front of the vertical stretch of 3 on the outside of the parenthesis.

From there when you draw the graph it should look like an upside down U shape with the highest point being (3,12) because that that is your vertex and 12 is your max.

The axis of symmetry would be 3.

The graph would increase at x is less than or equal to 3 and x would decrease at x is greater than or equal to 3.
