1x - 1y + 2z = -3 → 1x - 1y + 2z = -3 → 2x - 2y + 4z = -6
2x + 2y - 1z = -3 → 2x + 2y - 1z = -3 → 2x + 2y - 1z = -3
3x + 2y + 0z = 8 4x + 3z = -9
1x - 1y + 2z = -3
2x + 2y - 1z = -3 → 2x + 2y - 1z = -3 → -2x - 2y + 1z = 3
3x + 2y + 0z = 8 → 3x + 2y + 0z = 8 → 3x + 2y + 0z = 8
x + z = 11
4x + 3z = -9 → 4x + 3z = -9
1x + 1z = 11 → 4x + 4z = 44
-z = -53
-1 -1
z = 53
x + z = 11
x + 53 = 11
- 53 - 53
x = -42
3x + 2y = 8
3(-42) + 2y = 8
-126 + 2y = 8
+ 126 + 126
2y = 134
2 2
y = 67
(x, y, z) = (-42, 67, 53)
The answer is B.
Answer:
28
Step-by-step explanation:
f(6) = -3 * 6 + 10 = -18 + 10 = -8
g(f(6)) = g(-8)
g(-8) = 
= 64 - 24 - 12 = 64 - 36 = 28
If the book stores sells 5 books for 27.25, then 1 book costs
27.25/5=5.45
the online store sells one book with the price of
32.16/6=5.36
the online store has a lower unit price
Answer:
X<10 and x<4
Step-by-step explanation:
The absolute value bars around the x-7 means that the problem is less than 3 and less than negative 3, so you must solve for both to find all correct answers
