So plug in the number of passengers into each equation and see which answer matches Layton's. then from all the answers you find from plugging in the number of passengers, choose the cheapest one for B
Answer:
y = -x + 2
Step-by-step explanation:
Lines that are parallel have the same slope but different
y-intercepts.
So the slope of the parallel line is -x
We can input the x and y points given to solve for the new y-intercept
- y = -x + b
- 8 = -(-6) + b
- 8 = 6 + b
- b = 2
The new line is y = -x + 2. Since these two lines are the same, they are coinciding lines.

The possibilities are endless
If we're talking between 1-20
then the numbers divisible by 2 and 6 are
18,12,6
Answer:
C
Step-by-step explanation:
Given 2 secants intersect a circle from a point outside the circle, then
The product of the external part and the entire part of one secant is equal to the product of the external part and the entire part of the other secant, that is
x(x + 10 + x) = 6(6 + 10 + x)
x(2x + 10) = 6(16 + x) ← distribute parenthesis on both sides
2x² + 10x = 96 + 6x ← subtract 96 + 6x from both sides
2x² + 4x - 96 = 0 ← in standard form
Divide through by 2
x² + 2x - 48 = 0 ← factor the left side
(x + 8)(x - 6) = 0
Equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x - 6 = 0 ⇒ x = 6
However x > 0 ⇒ x = 6 → C
