Answer:

The value of x is -16.

Step-by-step explanation:

☆Let's solve!

\:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \frac{2}{3} x + 1 =  \frac{1}{6} x - 7 \\  \frac{ -  \frac{1}{6}x \:  \:  \:  \:  \:  \:  \:  \:  \:  =  -  \frac{1}6{x}  }{ \frac{1}{2}x  + 1 =  - 7}  \\   \:  \:  \:  \:  \: \frac{ - 1 =  - 1}{ \frac{ \frac{1}{2} x}{ \frac{1}{2} }  =  \frac{ - 8}{ \frac{1}{2} } }   \\  x =  - 16

We have
 -2x-3y <12
 For this case what you should do is to graph the following straight line:
 -2x-3y = 12
 Then, the solution will be the shaded region that satisfies the following inequality:
 -2x-3y <12
 In the shaded region you will find all the solution points.

What is the value of d21+d22+d23 given the matrix equation below?
sleet_krkn [62]

Answer:

B. 8

Step-by-step explanation:

The question lacks the required diagram. Find the diagram in the attachment.

Before we can find d21, d22 and d23, we need to get the matrix D first as shown in the attached solution.

On comparison as shown in the attachment, d21 = 11, d22 = -10 and d23 = 7

Note that d21 refers to element in the second row and first column of the matrix

d22 is the element in the second row and second column of the matrix

d23 is the element in the second row and third column of the matrix

d21+d22+d23 = 11-10+7

d21+d22+d23 = 8

The second option is correct.
