Mathematics
1 answer:

D. (2,3)

Explanation:

We already know that x=2, so of we plug in 2 for x, we should get the y value.

Once we plug in 2 for x we should get the equation:

2(2)+3y=13.

Simplify that and we get:

4+3y=13.

Subtract 4 from both sides and we get:

3y=9.

Divide both sides by 3 and we get:

y=3.

This means that your ordered pair should be (2,3).

Hope this helps :)

Jacket is originally priced at $120 it is on sale for 1/3 off which means that if you divide 120 by 3 you will get 40.  but you would have to subtract the 40 from 120 giving you 80

Need answers quick. Find the endpoint of the line segment with the given endpoint and midpoint. Endpoint: (−6,−6) Midpoint: (−2,
HACTEHA [7]

Answer: The second endpoint is  (2,6)

Step-by-step explanation:

\frac{-6 +x}{2} = -2  solve for x  

-6 +x = -4

+6        +6

x= 2

\frac{-6+y}{2} = 0  

-6 + y = 0

+6         +6

 y= 6

Suppose the coefficient matrix of a linear system of three equations in three variables has a pivot in each column. Explain why
Elis [28]

The system has a unique solution. Because the augmented matrix can be reduced to the form of the identity matrix.

<h3>What exactly is a linear system?</h3>

It is an equation system in which the maximum power of the variable is always 1. A figure with only one dimension and no breadth. It is made up of infinite dots placed side by side.

The augmented matrix must be reduced to the form of the identity matrix since there are three pivots one in each row.

Whatever is on the opposite side of the equal sign, there is a solution that is specific and exists.

Hence, the system has a unique solution.
