Answer:
Advanced tickets=30 Day =20
Step-by-step explanation:
Put them into equations:
x=advanced
y=day
x+y=50
25x+15y=1050
to make it simpler re-arrange x+y=50
x=50-y
Then substitute into 25x+15y=1050
25(50-y)+15y=1050
Expand
1250-25y+15y=1050
Rearrange
25y-15y=1250-1050
Work the above out
10y=200
y=20
and then
20+x=50
meaning....
x=30
showing Advanced tickets=30 Day =20
Answer:
x=2
Step-by-step explanation:
x + 4 = 3(3x - 4)
Distribute
x+4 = 9x -12
Subtract x from each side
x+4 -x = 9x-x-12
4 = 8x-12
Add 12 to each side
4+12 = 8x-12+12
16 = 8x
Divide by 8
16/8 = 8x/8
2 =x
Answer:
24
Step-by-step explanation:
If this is an answer 24 because when there were 50 tickets sold there were 12 so when there is 100 tickets sold you double 12 to get 24
Hope this makes since and please do not come after me if this is wrong.
Okay so I attatched pictures of my work. I would just graph it by plugging in x-values on either side of the vertex into the equation. For example, the vertex is at (-2,3). So try plugging x=-5 and x=1 into the equation (y=a(x-h)^2 +k).
y=(x+2)^2 +3
y=((1)+2)^2 +3=(3)^2+3= 9+3=
12
Now you can plot the vertex (-2,3), the point (1,12), and (-5,12). From there just connect the dots and you should get a graph that looks similar to the last picture I attached. Hope this all made sense sorry it was so wordy I just wasn't sure how much you knew or didn't know. So, I thought it would be better to explain it all rather than not enough.
