The solution to the system of equations is x = 3 and y = 10

<h3>How to solve the equations?</h3>

The system is given as:

2x-2y=-14

3x-y=-1

Multiply (1) by 1 and (2) by 2

So, we have:

1(2x-2y=-14)

2(3x-y=-1 )

This gives

2x - 2y=-14

6x - 2y=-2

Subtract the equations

-4x = -12

Divide by -4

x = 3

Substitute x = 3 in 3x-y=-1

3(3)-y=-1

Evaluate

9 - y = -1

Solve for y

y = 10

Hence, the solution to the system of equations is x = 3 and y = 10

The Yu family and the Sainz family went on vacation together and each family leased a car. The leasing company charged a flat re
Dafna11 [192]

Answer:

y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

Step-by-step explanation:

Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.

Let flat rental fee be c and cost per mile driven = m and miles driven = x

Total cost =y

Then y = mx+C is the linear equation.

to find m and c, we use the fact that y =110.30 when x = 222

i.e. 110.30 = c+222x

and similarly 99.05 = c+147x

Subtract to eliminate c

11.25 = 75 x

0.15 =x

Substitute in I equation

110.30 = c+222(0.15)

c = 77

Hence y = 0.15x+77 is the equation linear connecting total cost y and miles driven x

Hello!

We can go through the choices and see if they are true

Choice 1
A function has one output for every input

This is not a function because it has -1 as an output for both 4 and -1

This is the answer
------------------------------------------------------------------------------------------------------
Choice 2
The inputs are the x's

We see that the inputs are -1, 0, 3, and 4

This is true
------------------------------------------------------------------------------------------------------
Choice 3
The outputs are the y's

We see the outputs are -2, -1, and 1

This is true
------------------------------------------------------------------------------------------------------
Choice 4
We can follow the lines and see the relations are

(-1, 1), (0, -2), (3, 1), (4, -1)

This is also true
------------------------------------------------------------------------------------------------------
The only one that was false was the first choice so that is the answer

The answer is A) The diagram represents a function
