aleksley [76]

The equation represents the total reimbursement (R) he should expect to see in his bank account when he comes back is R = 30 + 1.25m.

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Carson is going on a work trip. He will get reimbursed for his expenses for driving his own car.

He will get a flat rate of 30, plus $1.25 per mile (m) he drives.

The equation formed;

R = 30 + 1.25m

The equation represents the total reimbursement (R) he should expect to see in his bank account when he comes back is R = 30 + 1.25m.

marta [7]

Answer:

At 10:30 A.M.

Step-by-step explanation:

A college offers shuttle service from Dickson Hall or Lot B to its  campus quad.

At 9:10 A.M the first shuttle leaves from their locations for the campus.

If the shuttles leave from Lot B every 10 minutes and leave from Dickson Hall every 12 minutes, then both the shuttles will leave their origin at the same time after 60 minutes.

This is because 60 is the smallest multiple of 10 and 12 which is common for them.

Therefore, 10:30 A.M. is the next time when both shuttles will depart for the campus at the same time. (Answer)

7. What is the system of equations that describes the following graph?
Volgvan

Answer:

The system of equations that describes the graph is:

x + y = 3

2x + 2y = 1

Step-by-step explanation:

Parallel lines have:

  • Same slopes
  • Different y-intercepts
  • The system of equations which represent them is y = m x + b and y = m x + c, where b and c are the y-intercepts

Let us find the equation of each line

∵ The solid line passes through points (3 , 0) and (0 , 3)

∵ m = Δy/Δx

∴ Δy/Δx =  \frac{3-0}{0-3}=\frac{3}{-3}

∴ m = -1

∵ b is the y-intercept (value y at x = 0)

∵ y = 3 at x = 0

∴ b = 3

∴ y = - x + 3

- Add x to both sides

∴ x + y = 3 ⇒ (1)

∵ The dashed line passes through points (0.5 , 0) and (0 , 0.5)

∵ m = Δy/Δx

∴ Δy/Δx =  \frac{0.5-0}{0-0.5}=\frac{0.5}{-0.5}

∴ m = -1

∵ b is the y-intercept (value y at x = 0)

∵ y = 0.5 at x = 0

∴ b = 0.5

∴ The equation of the line is y = - x + 0.5

- Add x to both sides

∴ x + y = 0.5

- Multiply both sides by 2

∴ 2x + 2y = 1 ⇒ (2)

The system of equations that describes the graph is:

x + y = 3

2x + 2y = 1
