The answer is going to be = 4m + 19
That is what you get after doing all the math
Answer:
<h3>Question 1</h3>
- Let number of adult tickets - x, student tickets - y
<u>Required equations:</u>
- x + y = 8
- 7.25x + 5.50y = 52.75
<u>Solve by substitution x = 8 - y</u>
- 7.25(8 - y) + 5.50y = 52.75
- 58 - 7.25y + 5.50y = 52.75
- 1.75y = 5.25
- y = 5.25/1.75
- y = 3
<u>Find x:</u>
Answer: 5 adults and 3 students
<h3>Question 2</h3>
- Pair of gloves costs- x, hats cost- y
<u>Equations:</u>
<u>Solve by elimination, subtract the equations:</u>
- 2y = 43 - 30
- 2y = 13
- y = 6.5
<u>Find x:</u>
- 2x = 30 - 13
- 2x = 17
- x = 8.5
Answer: Gloves cost $8.5, hats cost $6.5
The product of denominators can always serve as the common denominator. The appropriate choice is ...
... z times u . . . . . . . the first choice
Y= (x-2)² + 5. We can write it as : y-5 = (x-2)². The general equation of a quadratic function is :
(y-k) = a(x-h)², where h and k are the vertex of the parabola and a, the coefficient which determines whether the parabola opens upward or downward.
So, y-5 = (x-2)²
Having said that we can say that the VERTEX( 2,5) and since a=1 (a>0) the parabola is open upward OR it passes by a MINIMUM (Then the vertex is minimum)
The domain (x- value) is all Real { x|x = -∞ to x=+∞}
The Range (y-value) is all y ≥ 5
