Answer:
y = -6, x =2
Step-by-step explanation:
To solve by elimination, you have to line both equations up together. Then, you multiply both equations until one variable is removed.
2x+y = -2
5x + 3y = - 8
There are many different ways to solve an elimination problem, but generally you should look for the simplest route. Here, I would multiply the top equation by -3.
-6x -3y = 6
5x +3y = -8
Imagine you are adding the two equations together. You end up with
-x = -2
Then solve for x. In this situation, it is fairly simple. Take out a factor of -1.
x = 2
Finally, choose one of your beginning equations and plug your new-found x value back into the equation.
2(2) +y = -2
4 + y = -2
y = -6
Answer:
4/24 + 9/24 = 13/24
Find a common denominator which would be 24 atleast.
Answer:every point on the original graph is an ordered pair (x,y) where y = f(x). For the second graph, the y values will be doubled in each case, for the original x values. So this is a VERTICAL STRETCH.
Answer:
Step-by-step explanation:
I'll tell you how to find the answers and just use the give angle measure to solve.
9) angle 11 = angle 14
10) angle 9 + angle 15 = 180
11) angle 10 = angle 3
12) angle 7 = angle 14
