No, they are not. You can write ratio in different ways, so I did 2/3 = 9/6. I cross product, which is 2 × 6 and 9 × 3. Both of the answer did not match, so that tells me they are not proportional.
Answer: A. 90° clockwise, E. 270° counterclockwise
4s+7a=861
s+a=168
This can be solved using either elimination or substitution. I am going to use substitution.
Solve s+a=168 for s
s=168-a
Replace 168-a for s in 4s+7a=861
4(168-a)+7a=861
672-4a+7a=861
Solve for a
672+3a=861
3a=189
a=63
Substitute 63 for a in s=168-a
s=168-63=105
So, s=105 student tickets and a=63 adult tickets
Answer:
$68y
Step-by-step explanation:
i just thought of it don't ask
(F^(-1))x = 2x-4. Or y=2x-4
1. Switch the x and the y
2. Solve for y in the new equation
3. Change the y to inverse function of x.
