Answer:
5(3x-2y)
Step-by-step explanation:
In this question we are given an expression 7 (x-2y) - 4 (2x+y).
Now, we have to simplify this expression after distribution.
So, 7(x-2y)+4 (2x+y)
=7x -14y +8x +4y {This is the distribution. Here we have used the distributive property that, a(b+c) =ab +ac}
=15x -10y {Separating the x and y terms}
=5(3x-2y) {Taking 5 as common from both the terms}
(Answer)
Answer:
C
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
Here [ a, b ] = [ - 10, 10 ], thus
f(b) = f(10) = 10² + 9(10) + 18 = 100 + 90 + 18 = 208
f(a) = f(- 10) = (- 10)² + 9(- 10) + 18 = 100 - 90 + 18 = 28, thus
average rate of change = = = 9
A verticals line through 3 on the x axis
Answer:its just going up
Step-by-step explanation:
It would be the first one because it is written in vertex form and from that the vertex would be (-5,-6), meaning that the aos would be -5.
hope this helps!! :))
