Answer:You already answer the question what is there to answer again?
Step-by-step explanation:
Step-by-step explanation:
<u>to show how many tickets were sold:</u>
x = upper floor tickets
y = main floor tickets
x + y = 2000
<u>to show total amount of revenue:</u>
25x + 40y = 62,000
<u>Finding answer using both equations:</u>
x + y = 2000
multiply each side by 25
25x + 25y = 2000 × 25
25x + 25y = 50,000
25x + 40y = 62,000
-
25x + 25y = 50,000
-----------------------------------
15y = 12,000
^ this is column subtraction
<em>^ this column subtraction is done to isolate y so we can work with one value rather than 2</em>
15y = 12,000
divide each side by 15
12,000 ÷ 15 = 800
y = 800
x + y = 2000
x + 800 = 2000
x = 1200
Therefore 1200 upper-level tickets were sold
800 main floor tickets were sold
Answer:
the answer its 7^2 +7^3x5 its d hope helps you
Step-by-step explanation:
You can determine this by finding zeros of quadratic function,
.
Which eliminates first and third option.
Now we have up and down parabolas left.
If we factor
we find that the coefficient before
determines how it is turned, since its positive its an upward turned parabola hence the answer is the last graph.
Hope this helps.
