A cubic yard is equal to 27 cubic feet.
And one cubic yard is 2 tons.
Answer:
13
Step-by-step explanation:
It depends on which variable is eliminated.
If you multiply the second equation by -1 and eliminate the y:
3x - y = 7
-6x + y = -10
-3x = -3 or x = 1
If you multiply the first equation by -2 and eliminate the x:
-6x + 2y = -14
6x - y = 10
y = -4
As per definition
In. a function every domain has an unique range of it
Here
- f(4)=6
- f(10)=-2
- f(13)=7
- d(15)=8
- f(10)=11
f(10) has two corresponding values hence it's not a function
