                                                        =30-23

4. Use the substitution method to determine the solution to this system of equations.
N76 [4]

Answer:

No solution

Step-by-step explanation:

6X - 3Y = -9--------------(1)

- 2 X +Y= 5---------------(2)

from equation two,

Y = 5+2X------------------(3)

substitute equation (3) into equation (1)

6X-3(5+2X)= -9

opening bracket

6X-15-6X= -9

6X- 6X = -9+15

0 = 6

<h2>therefore the answer is no solution</h2>

Hodel just got her driver's license. Her parents offer her two options. 1. They'll buy her a used car that will cost her $0.50 p
Romashka-Z-Leto [24]

Answer:

The second option will cost her less than the first one.

Step-by-step explanation:

In order to solve this problem we will create two functions to represent the cost of the car in function of the miles drove by her.

For the first option we have:

cost_1(x) = 0.5*x

For the second option we have:

cost_2(x) = 5000 + 0.1*x

Since she intends to drive it for 10,000 miles per year for 6 years, then the total mileage she intends to drive her car is 60,000 miles. Applying this to the formula of each car and we have:

cost_1(60000) = 0.5*60000 = 30000

cost_2(60000) = 5000 + 60000*0.1 = 11000

The second option will cost her less than the first one.

PLEASE HELP!!! <br> show work if possible!:)
satela [25.4K]

Answer:

The answer to your question is y = 2x + 11

Step-by-step explanation:

Data

Original line   y = -(1/2)x + 5

Point (-4, 3)

Process

1.- Get the slope of the new line

- Slope of the original line = -1/2

  If the lines are perpendicular, the slopes must be reciprocal

                       -1/2  reciprocal = 2

2.- Get the equation of the new line

          y - y1 = m(x - x1)

          y - 3 = 2(x + 4)

- Simplification

         y - 3 = 2x + 8

- Solve for y

        y = 2x + 8 + 3

        y = 2x + 11
