The answer to the question is B
C;
8x + 4y = 20
4y = 20 - 8x
y = 5 - 2x
Answer:
6x + 2
Step-by-step explanation:
2(3x + 1)
Multiply 2 with 3x and 1.
<u>6x + 2</u>
Answer:
5
Step-by-step explanation:
There are 6 numbers on a die, one of them is 5 so we expect to get a five one of six times
P (5) = 1/6
If we roll the die 30 times, we expect to get a five 30 * 1/6 = 5 times
AX = B
1 -1 -1 x 0
0 -2 -1 y = -2
2 1 0 z -4

y = A^-1 B

y = 2 -2 -1 . 2 = -8
z -4 3 2 4 14
