Answer: x=-2
Y= -20
Step-by-step explanation
You replace the y in the second equation with 10x. This is because it says 10x=y
2x+10x=12x so you put that
12x=-24
To get x by its self you divide by 12.
-24 divided by 12 is -2.
Now you plug in -2 to either equation as y. I chose the first one because it's easier.
10(-2)=y
-20=y
Answer:
The relation is not a function.
Step-by-step explanation:
Since x = 0 produces y = 2 and y = -2, the relation (0,2), (1,3), (0,-2), (2,4) is not a function.
Seven to the third power is
(7^3)
7 * 7 * 7
this is
49 * 7
which is
343
