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
Think it’s seven and eight and nine
Answer:
152 gallons
Step-by-step explanation:
76÷4=19
19x8=152
solve for y
2x−4y=10
-2x -2x subtract -2x from both sides
-4y = -2x +10
-4 -4 Divide both sides by -4 (coefficient on y)
y = -2/-4x + 10/-4
y = 1/2x - 5/2
the slope is the number on the x (coefficient)
and its 1/2
