No I do not agree with (2,-4) I believe the solution is (-4,2)
The y-intercept is being changed. In the equations given we are using the formula (y=mx +b), b means the y intercept. In this we are changing the y intercept from 2 to -1. There is nothing else being changed.
Answer:
y=x+5
Step-by-step explanation:
if y is the total cost then the equation y = x +5 where x is the miles driven and $5 is the initial cost would accurately represent the cost of your cab ride.
Answer:
This is a classical problem which has delighted calculus students down through the ages.
We first express the volume of the box as a function of x, the side of the square which is cut out of each corner.
The resulting box will have a base which is a square which all of whose sides will have length 12 - 2x. The height of the box will be x. Therefore, the volume will be
V = (12 - 2x)2x
= 144x - 48x2 + 4x3
