Answer:
1/3 = x
Step-by-step explanation:
Answer:
is the questions even correct? recheck the units
Supplementary means that they add up to 180 degrees. Those 2 angles should add up to 180 degrees. X is the missing angle and 42 degrees is the other angle. If both are added together they equal 180. To find x we can simply subtract 42 from 180 to get the x. 138 is x. The proof is that if 138 and 42 are added together they end up making 180 degrees. Therefore, the answer is 138
Answer:
Step-by-step explanation:
You are looking for the point of intersection of these two functions.
Substitution:
- This are now your formulas
- You are going to substitute x, so you can solve for y
- Now you are going to substitute y to find x
- Now lets check if it is correct
So it is true, making (-4 , -5) your point of intersection.
hope it helps
Sur it's a function because for each x value corresponds one and only one y value.
Another easy way to determine if y is a function is to apply the vertical test:
If you draw a vertical line and this lines intersects the graph in one point, then y is a function
