Answer:he paid for 6 hours to have the bike checked out.

Step-by-step explanation:

Oceanside Bike Rental Shop charges 13 dollars plus 9 dollars an

hour for renting a bike. Let x represent the number of hours that a person rents the bike. The total amount paid for renting the bike for x hours would be

13 + 9x

Mike paid 67 dollars to rent a bike. This means that

13 + 9x = 67

Subtracting 13 from both sides of the equation, it becomes

9x = 67 - 13 = 54

x = 54/9 = 6

In this question, we're trying to find how many hours Mike had the bike for.

We know that 13 dollars as a flat rate.

We also know that they charge 13 dollars and hour.

Mike paid a total of 67 dollars for the bike.

Lets represent this as an equation:

67 = 9x + 13

x = hours the bike was rented

Solve for x:

67 = 9x + 13

Subtract 13 from both sides

54 = 9x

Divide both sides by 9

6 = x

This means that Mike rented the bike for 6 hours.

Answer:

6 hours

A car trip from New York to Cincinnati took 12.5 hours. The return trip by the same route took 1 hour longer because the average

zhenek [66]

A car trip from New York to Cincinnati took 12.5 hours. The return trip by the same route took 1 hour longer.

Let x be the speed of the car

Car trip from New York to Cincinnati

We know Distance D = speed * time

time = 12.5 hours and speed =x

D = 12.5x

Return trip

The return trip by the same route took 1 hour longer. So 12.5+1 = 13.5 hours

he average rate of speed was 4 mph less. So speed is x-4

Distance D = speed * time

time = 13.5 hours and speed =x-4

D = (x-4)*13.5

D= 13.5x-54

The distance of ongoing trip and return trip are same

So we equate both the distance equations D= 13.5x-54 and D= 12.5x

12.5x = 13.5x-54

Subtract 13.5 on both sides

-1x = -54

x=54

speed of ongoing trip = 54 miles per hour

Distance D = 12.5x = 12.5 * 54=675 miles

The length of the route = 675 miles

What is an equation for the linear function whose graph contains the points (−1, −2) and (3, 10)

sladkih [1.3K]

The equation of a line starting from two points is:
$y-y_1=\frac{y_2-y_1}{x_2-x_1} \cdot (x-x_1)$

From the first point you get: x1 = -1, y1 = -2
From the second point you get: x2 = 3, y2 = 10

Replace x1, y1, x2, y2 in the equation of the line and you get:
$y+2=\frac{10+2}{3+1} \cdot (x+1)$
$y+2=\frac{12}{4} \cdot (x+1)$
$y+2=3 \cdot (x+1)$

From this you get the equation of your line:
$y(x)=3x+1$
