Answer: 210 advanced tickets were sold. 130 same day tickets were sold.
Step-by-step explanation:
x= advanced tickets y=same day tickets
2x+3y=810 this equation represents the money
x+y=340 this equation represents the total number of tickets
x+y=340
<u>-x -x</u>
y=-340-x 2x+3(340-x)=810 210+y=340
2x+1020-3x=810 <u> -210 -210 </u>
-x+1020=810 y=130
<u> -1020 -1020</u>
<u>-x</u>=-<u>210</u>
-1 -1
x=210
Answer:
$2.25
Step-by-step explanation:
Let c represent the cost of a cup of coffee. Then the total amount paid for 3 cups is ...
3c + 3c·0.08 = 7.29
3.24c = 7.29
c = 7.29/3.24 = 2.25
A cup of coffee costs $2.25.

I don't know what a "pointd" is, but I suggest you not make promises you cannot keep.
Answer:
Option D.
Step-by-step explanation:
It is given that triangle ABC reflected in the y axes so that the image of triangle ABC is triangle A'B'C'.
Let A(a,b) and B(c,d). So, after reflection A'(-a,b) and B'(-c,d).
Using distance formula,
So,
We know that reflection is rigid transformation, it means figure and its image must be congruent.
If triangle ABC is read clockwise, then after reflection triangle A'B"C' is read anticlockwise.
Since statements I, II and IV are true, therefore the correct option is D.
Answer:
(-2,2)
Step-by-step explanation:
If you graph the equations (I recommend using desmos) you can see that the points intersect at that point.
