To take a taxi, it costs \$3.00$3.00 plus an additional \$2.00$2.00 per mile traveled. you spent exactly \$20$20 on a taxi, which includes the \$1$1 tip you left. how many miles did you travel?

8 miles

Step-by-step explanation:

Given:

To take a taxi initial cost = $ 3.00

Per mile cost =  $ 2.00

Total spent = $20

Tip Given = $ 1

To find:

Total miles traveled=?

Solution:

Now the total cost f the ride was $ 20

As we see that initial cost for all the trips would stay the same

Let someone travels x miles

then according to the given

Initial cost + 2 * miles traveled + tip = total cost

Putting from the given values it becomes

3 + 2 * x + 1 = 20

Now we have to find x here which is the total miles traveled

solving the above equation

3+1+2x=20

4+2x=20

2x=20-4

2x=16

dividing both sides by 2

x =8 miles

so total miles travelled by the person is 8 miles

8 miles you traveled.

Step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
