Answer:
y = (1/2)x is proportional; (1/2)
Step-by-step explanation:
1. y= 1/2x Proportional; constant of proportionality is 1/2.
2. y=2x + 7 Not proportional because of the non-zero y-intercept.
3. x= y + 2 Not proportional (same a reason as for #2)
There are an infinite number of them. The smallest one is 42,
and every multiple of 42 is another one.
I don't remember the official correct way to solve this problem.
I can only show you my own way of doing it.
I take the bigger number, and I go through its multiples, one by one,
until I spot one that's also a multiple of the smaller one.
Example: 6 and 7.
Go through the multiples of 7:
7 ... no, not a multiple of 6
14 ... no, not a multiple of 6
21 ... no, not a multiple of 6
28 ... no, not a multiple of 6
35 ... no, not a multiple of 6
<em><u>42</u></em> ... Yes ! A multiple of 6. yay !
Answer:
A: $4.64
B: About 34%
Step-by-step explanation:
A: Subtract 7-2.36
B: 2.36(100)= 236
236/7 =33.714285
Then estimate
-2xy + 5x² +4y -10x
