Answer:
Let b = profit on a blue car
w = profit on a white car
r = profit on a red car
b = w + 10 (1)
r = w - 7 (2)
2r = b -2
2r-b= -2 (3)
Subtract eq. (2) by 2q. (1)
r - b = 0 - 7 - 10
r - b = -17 (4)
Subtract eq. (3) by eq. (4)
r - 0 = -2 - (-17)
r = 15
in eq (2)
r = w - 7
15 = w - 7
w = 22
in eq (1)
b = w + 10
b = 22 + 10
b = 32
The profit on a blue car is $32
Step-by-step explanation:
THE ANSWER IS 32
The unit rate would be the price for 1 ticket.
12 dollars / 3 tickets = $4 per ticket.
The ratio would be 4:1
Based on the calculations, the equation of this parabola is equal to (x - 6)² = 16(y + 4).
<h3>How to determine the equation of this parabola?</h3>
Mathematically, the standard equation with the vertex for a parabola is given by:
(y - k)² = 4a(x - h) for horizontal parabola.
(x - h)² = 4a(y - k) for vertical parabola.
<u>where:</u>
By critically observing the points, we can deduce that both the focus and vertex lie on the same vertical line x = 6.
<u>Given the following data:</u>
Focus with points = (6, 2).
Vertex (h, k) = (6, –4).
<u>Note:</u> a = 2 - (-4) = 2 + 4 = 6.
Substituting the given parameters into the formula, we have;
(x - 6)² = 4 × 4(y - (-4))
(x - 6)² = 16(y + 4).

Answer:
2.5 hours
Step-by-step explanation:
To calculate the time taken to travel the distance, we will apply the distance speed time formula, which links the speed of an object, the distance traveled by it and the time taken for it to travel the distance as follows:
Time taken to travel the distance = Distance Traveled / Average Speed
We know the average speed to be 7 km/h
and the total distance traveled to be 17.5 km
Using these values and putting them in the equation we get,
Time taken = 17.5 / 7 = 2.5
