The new matrix that is formed by the 3A + B is given below. Then the value of x is 102.
<h3>What is the matrix?</h3>
A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The 
element in a matrix, such as M, refers to the i-th row and j-th column element.
The matrices are given below.
Then the new matrix is given as 3A + B. Then we have

Y + 5 = 0
y >= -5
Therefore, you would choose the first answer.
<span>1/5
This is a matter of elimination. So let's figure out how many of each display there is.
30% of 150 = 0.30 * 150 = 45 displays about electricity.
2/5 * 150 = 0.40 * 150 = 60 displays about renewable energy
1/10 * 150 = 150/10 = 15 displays about gas.
The rest of the displays are about nuclear power. So
150 - 45 - 60 - 15 = 30 displays about nuclear power. Since we want a fraction, we get 30/150
But 30/150 isn't in it's simplest form. The largest number that will evenly divide both 30 and 150 is 30. So divide both the numerator and denominator by 30
(30/30)/(150/30) = 1/5
So 1/5 of the displays are about nuclear power.</span>
Answer:
I believe the answer is C, -4/5.
Step-by-step explanation:
You first find two points on the line and substitute them into the slope formula. I used points (-10,10) and (5,-2).
1. 
2. -2-10/5-(-10)
3. -12/15
4. -4/5
