Answer:

y=2

Step-by-step explanation:

since the line is horizontal, on the point 2 on the y axis, the equation is 2. If, however the line were to be diagonal, it would have been different, as would it if the line were vertical(in which case, the equated would start x =)

Hope this helps

Which property is shown in the matrix addition below?<br> [-6 15 -2 ] + [6 -15 2 ] = [0 0 0

aksik [14]

Answer:

The property shown in matrix addition given is "Additive Inverse Property"

Step-by-step explanation:

First of all lets define what a matrix is.

A matrix is an array of rows and columns that consists of numbers. There are several types of matrices. The one in our question is a row matrix which consists of only one row.

There are several addition properties for matrices.

One of them is additive inverse property. The additive inverse of a matrix consists of the same elements but their signs are changed.

Additive inverse property states that the sum of a matrix and its additive inverse is a zero matrix.

$\left[\begin{array}{ccc}-6&15&-2\end{array}\right] + \left[\begin{array}{ccc}6&-15&2\end{array}\right] = \left[\begin{array}{ccc}0&0&0\end{array}\right]$

Hence,

The property shown in matrix addition given is "Additive Inverse Property"

A circus recently spent $1650 on new trapezes the trapezes cost $275 each write an equation that could be used to find the numbe

Andru [333]

Answer:

The equation for number of trapezes t is t = (total amount spent on trapezes)/(cost of each trapeze) and the circus bought 6 trapezes.

Step-by-step explanation:

In order to write an equation for the number of trapezes we first need to identify the variables that were given to us. The first one is the total amount of money spent on these trapezes, that is $1650, so the sum of the individual cost of all the trapezes should be equal to this value. The second information that was given to us is the individual price of each trapeze. With these two we can write the equation for t, where:

t = (total amount spent on trapezes)/(cost of each trapeze)

t = 1650/275 = 6
