Answer:

Therefore, the solution of the system of equations will be:

x=5,\:y=-1

Step-by-step explanation:

Given the system of equations

x-y=6;\:y=-1

solving

\begin{bmatrix}x-y=6\\ y=-1\end{bmatrix}

\mathrm{Subsititute\:}y=-1

\begin{bmatrix}x-\left(-1\right)=6\end{bmatrix}

\begin{bmatrix}x+1=6\end{bmatrix}

Isolate x for x+1=6

x+1=6

x=5

Therefore, the solution of the system of equations will be:

x=5,\:y=-1

If a single 20 sided dice is tossed once what is the probability of rolling a 15 or 17
Alex17521 [72]
For a single 20 sided dice, a chance to get a certain number would be 1/20. For 2 numbers it will be a 2/20 chance, which can be simplified to a 1/10 chance that you will roll a 15 or a 17.

The number of cars at a dealership dropped from 64 to 48 after a weekend sale.
Arada [10]
The answer is 25%

(1)
If 64 is 100%, 48 is how much percent:
64 : 100% = 48 : x
x = 100% * 48 : 64
x = 75

(2)
Percent of decrease is:
100% - x = 100% - 75% = 25%

Exploring Systems of Linear Equations 2x +3y =8 and 3x+y= -2
butalik [34]

The solution of the linear equations will be ( -2, 4).

<h3>What is an equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given equations are:-

  • 2x +3y = 8 and 3x+y= -2

Solving the equations by elimination method:-

2x +3y = 8

3x+y= -2

Multiply the second equation by 3 and subtract from the first equation.

2x +3y = 8

-9x -3y = 6

----------------

      -7x = 14

         x = -2

Out of the value of x in any one equation, we will get the value of y.

3x+y= -2

3 ( -2) + y = -2

-6 + y = -2

y = 4

The graph of the equations is also attached with the answer below.

Therefore the solution of the linear equations will be ( -2, 4).

The complete question is given below:-

Exploring Systems of Linear Equations 2x +3y =8 and 3x+y= -2. Find the value of x and y and draw a graph for the system of linear equations.
