Answer:
The answer is f(x)=2
Step-by-step explanation:
When the input is given it means that the x is substituted by that number.
so 3x3-7.
3x3-7
9-7=2.
The f of x is equivalent to 2.
I hope this helps :D
Answer:1
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
First line:
y = mx+b where m is the slope and b is the y intercept
y = 2x + 10
Second line
y = mx+b
y = 3x+0 since there are no barrels filled on this line when they flip the switch
Setting the two equations equal
2x+10 = 3x
Subtract 2x from each side
2x+10-2x= 3x-2x
10 = x
Each line will have filled 10 barrels when they numbers are equal.
