Function A isn't linear because it doesn't have a pattern on the y and Function B is a function because it has a pattern of .75 on the y or output
The solution is x=-3, y=1, z=-1
Answer:
B. 9 : 21
Step-by-step explanation:
Multiply numerator and denominator by 3:
... 3/7 × 3/3 = 9/21 ⇒ 9 : 21
_____
Any denominator that is not a multiple of 7 will not work. 35 is a multiple of 7 (=5×7), but 12 (=4×3) is not the same multiple of 3.
19y+63 is the correct answer
<span>9 - 3x - (-8y) + 9x -y
9 - 3x + 8y + 9x - y
9 - 3x + 9x + 8y - y
9 + 6x + 7y</span>
