The expression which shows the total cost is 2.50+0.4x and the cost of riding 20 miles is $10.50.
Given a taxi charges $2.50 for the first mile and $0.40 for each mile
We are required to make an expression showing total cost and total cost of a 20 mile ride.
let the miles ride by tax be x.
Total cost of the product or service=Number of units*price of one units.
We have been given that $2.50 is fixed so we will not multiply our variable charge with $2.50 and multiply 0.40 with x.
So,the expression showing looks like 2.50+0.40x.
Now to find the cost when taxi travels 20 miles, we have to put x=20,
Cost=2.50+0.40*20
=2.50+(40*20)/100
=2.50+800/100
=2.50+8
=$10.50
Hence the expression which shows the total cost is 2.50+0.4x and the cost of riding 20 miles is $10.50.

True. Using the equation y2-y1 / x2-x1
The new equation should look like this 5/1-3/1 and the equals to = 4/2 and that simplify is 2. So the answer 2 we just got is the slope. So we just add the letter x since that represents slope. Making the equation y=2x+1 true.

Answer:

Step-by-step explanation:
The slope-intercept form of an equation of a line:

Convert the equation of a line 3x + 4x = 2y - 9 to the slope-intercept form:

<em>add 9 to both sides</em>
<em>divide both sides by 2</em>

Parallel lines have the same slope. Therefore we have the equation:

Put the coordinates of the point (4, -4) to the equation:


<em>subtract 14 from both sides</em>

Finally we have the equation:
