Answer:
I just found it out, 200 Student tickets were sold.
Answer:
1/2*6(12+x)=12*x
1/2*(72+6)=12x
36+3x=12x
36=9x
4=x
Step-by-step explanation:
Check that x=4
1/2*6(4+12)=12*4
1/2*(24+72)=48
1/2(96)=48
48=48
So x=4 is the correct answer
Answer:
-2/3 (fixed it)
Step-by-step explanation:
Answer:
g(x) = (x + 3)^2
Step-by-step explanation:
When a function is shifted to the left or right we can think of a change of units, like a new independent variable is used.
If we have a quadratic function

and the graph is shifted 3 units to the left, then we can think of a new unit u that is:

The vertix of this parabola, that happens for u=0, happens for x=-3, as the graph is shifted 3 units to the left.
Then, the relation between u and x is:

We can use this relation in the new graph and replace u as:
