Answer:
C)
Step-by-step explanation:
Exponential means that something is growing faster as time goes by.
In C, we can see that at
x=1, f(x) is 2
When x=2, this doubles to 4. (+2)
When x=3, this becomes 8. (+4)
You can see that more is being gained at f(x) while x is only increasing by one. This shows exponential growth.

i really dont understand
Step-by-step explanation:
Answer:
x=12
Step-by-step explanation:
1+3x=37
First minus 1 on the left and right hand side.
1-1+3x=37-1
Whenever you move a number to the other side , the sign changes. For example, you need to move 8 to the right side. Then the sign changes from positive to negative -8.
3x=36
Divide by 3 for both sides.
x=12
Check the answer:
1+3(12)=37
37=37
Answer:
At the bottom!
Step-by-step explanation:
Put the two equations into the same standard form:
2x-y=8
-5x+2y=3
Now if you add the two equations up, guess what will happen?
You will "eliminate" the y variable, and only be left with the x variable.
Technically, you will get:
2x-y+2+28-5x+29+2y=8+23
-3x+20y=11
-3x=11
