Answer:
Option a
Step-by-step explanation:
First multiply matrix A by -4.
Then multiply the matrix B by 6.
When multiplying a matrix by a number x you must multiply each element of the matrix by x.
Then we perform operation -4A
Now we perform operation 6B
Now we add the resulting matrices
Answer:
answer choice 2
Step-by-step explanation:
Answer:
b=80
Step-by-step explanation:
5⋅b/5=5⋅16
If solving for x:
Because both equations are equal to Y, you can set both equations equal to each other:
5x+1=4x+8
Then it's a matter of simplification (subtract the 4x to the left side and subtract the 1 over to the right):
x=7
If solving for Y:
Plug x=7 into either equation and solve:
Y=4(7)+8
Y=36
Answer:
<h3>AB∣∣CD and EFEF is transversal</h3>
<h3>\Rightarrow \angle CHF=\angle </h3>
<h3>DHG⇒∠CHF=∠DHG (Vertically opposite angles)</h3>
<h3>If angles are equal then they are said to be congruent.</h3>
