Answer:

C=\left[\begin{array}{cc}1&4\\1&6\end{array}\right]

Step-by-step explanation:

<u>Matrix Addition</u>

Given two matrices A and B, the sum of A+B can only be defined if both matrices are of the same order, i.e. they have the same number of files and columns. If that was the case, then the sum of A and B, call it C is defined as

c_{i,j}=a_{i,j}+b_{i,j}

In other words, the resulting sum at row i and column j is the sum of the elements in that exact position

We are given the matrices

\left[\begin{array}{cc}-2&3\\2&4\end{array}\right] +\left[\begin{array}{cc}3&1\\-1&2\end{array}\right]

Adding them at the same position, we have

C=\left[\begin{array}{cc}-2+1&3+1\\2-1&4+2\end{array}\right]

C=\left[\begin{array}{cc}1&4\\1&6\end{array}\right]

Select option c.

How many ways can an employer send 3 employees to a job fair if she has 11 employees?
algol13

We have to find the number of ways an employer send 3 employees to a job fair if she has 11 employees.

This is the problem from combination.

The formula for combination is given by

^nC_r= \frac{n!}{r!(n-r)!}

Here, n= 11, r= 3

Therefore, total number of ways is given by

^{11}C_3= \frac{11!}{3!(11-3)!}\\&#10;\\&#10;=\frac{11!}{3!8!}\\&#10;\\&#10;=\frac{8!\times 9 \times 10 \times 11}{3!8!}\\&#10;\\&#10;=\frac{9 \times 10 \times 11}{6}\\&#10;\\&#10;=165

A is the correct option.

Write the equation of the line that contains the points (4, −7) and (1, 5). The slope of the line that contains the points (4, −
deff fn [24]
Slope = (5+7)/(1-4) = 12/-3 = -4

slope = -4

y = mx + b
-7 = -4(4) + b
-7 = -16 + b
b = 9

equation
y = -4x + 9
