The answer is
x + y = 7
6.50x + 3.50y = 33.50
x - the number of adult tickets
y - the number of child tickets
<span>Group of 7 people: x + y = 7
</span> 6.50 adults and 3.50 for child ticket cost <span>33.50: 6.50x + 3.50y = 33.50
So, we have two equations:
</span>x + y = 7
6.50x + 3.50y = 33.50
Answer:
9x^2-3x+4
Step-by-step explanation:
(3x^2+2x^2-5x+7)+(4x^2+2x-3)
5x^2-5x+7+4x^2+2x-3
5x^2+4x^2-5x+2x+7-3
9x^2-3x+7-3
9x^2-3x+4
Vertex form for a parabola with vertex (p,q) is

We have (p,q)=(-4,5) and another point (-3,2) so we can solve for <em>a:</em>



Putting it together,
Answer: 
We could multiply that out if we like but I won't bother.
