The line models the cost of renting a bike. It costs $2 per hour plus a $4 deposit. Write an equation in slope-intercept form for the line where x is the number of hours a bike is rented and y is the total cost of renting a bike.

Answers

y=2x+4 because $2 per hour and then adding your $4 deposit

The equation of the line will be written as y=2x+4 because $2 per hour and then adding your $4 deposit.

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that the line models the cost of renting a bike. It costs $2 per hour plus a $4 deposit.

The equation of the line is,

y = 2x + 4

Here, $2 per hour and then add your $4 deposit.

Answer:

Step-by-step explanation:

Points D and E are midpoints of the sides of triangle ABC. The perimeter of the triangle is 48 units. Triangle A B C is shown. Point D is the midpoint of side A B and point E is the midpoint of side B C. The lengths of A D and D B are 3 t, the lengths of B E and E C are 4 t, and the length of A C is 7 t + 6. What is the value of t? 2 3 6 8

Answers

Answer:

Step-by-step explanation:

From the diagram attached :

AB = AD + BD = 3t + 3t = 6t

BC = BE + EC = 4t + 4t = 8t

AC = 7t + 6

Perimeter of the triangle = 48

Perimeter of a triangle (P) :

P = AB + BC + AC

48 = 6t + 8t + 7t + 6

48 - 6 = 6t + 8t + 7t

42 = 21t

t = 42 / 21

t = 2

Answers

Answer: Let's solve for x.

−x=y+6

Step 2: Divide both sides by -1.

−x

x=−y−6

Answer:

x=−y−6

Let's solve for x.

5x−7y=66

Step 1: Add 7y to both sides.

5x−7y+7y=66+7y

5x=7y+66

Step 2: Divide both sides by 5.
