Answer:
b = -2
Step-by-step explanation:
1) Cross multiply the proportion, in turn, you receive 2(b-4) = 6b.
2) Simply said equation, you should have 2b - 8 = 6b.
3) Subtract the 2b from each side, effectively canceling it out on the left (original position) and resulting in 6b to become 4b (6b - 2b = 4b).
4) After you have -8 = 4b, you can divide both sides by 4, canceling out on the right (original position).
5) You are finally left with -2 = b, reversing this results in b = -2.
-2 is your answer.
X/-10 = 7
Step 1: Multiply by -10
(x/-10)*-10 = 7*-10
x = -70
Answer:
Step-by-step explanation:
For two matrix P and Q, the product, say PQ is defined when:
The number of columns of P = The number of rows of Q
Since A is a 2×2 matrix and B is also a 2×2 matrix
Thus both AB and BA are possible.
So AB is:
BA is:
