Step-by-step explanation:
for any matrix multiplication number of columns of first matrix should be equal to number of rows of second matrix.
For AB
A has 3 columns and B has 3 rows so it matches . Hence can be multiplied.
For BA
B has 2 columns and A has 2 rows it also matches so can be multiplied
Answer:
You are now 38 m below base camp.
Step-by-step explanation:
Consider the provided information.
You start hiking at an elevation that is 80 meters below base camp.
Now your initial location is 80 m below base camp, that can be represents as: -80
Now you increase your elevation by 42.
So you go up by 42.
In other words, you get the equation -80+42 = -38.
Since, a negative value is below the base camp, this means that you are now 38 m below base camp.
2(6x+11)-4x=14
12x+22-4x=14
8x=-8
x=-1
y=6(-1)+11
y=5
(-1,5)
Express all possible lengths for this scrap as a compound inequality will be L ≤ 24.
<h3>What is inequality?</h3>
Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
To repair a leak a plumber needs a pipe that is within 3/4 of an inch of 32 inches.
⇒ 3/4 x 32
⇒ 24
He already has a 48-inch pipe.
Let the variable L represents the length of the extra (scrap) that is removed from the 48-inch pipe will be
Then express all possible lengths for this scrap as a compound inequality will be
L + 24 ≤ 48
L ≤ 48 - 24
L ≤ 24
