It is! When you're doing a fraction specifically like that, the denominators cancel out. Therefore you can get rid of the 12. It just becomes 21/7, which as you know is 3.
Hope that helps :)
Answer:
FALSE
Step-by-step explanation:
If y varies inversely as x., this is expressed as;
y = k/x
k is the proportionality constant
when y = 3 and x = 4
3 = k/4
k = 3 * 4
k = 12
when x = 15;
y = k/x
y =12/15
y = 4/5
Hence y is not equal to 12 when x = 15.
The correct answer is FALSE
Answer:
c and d
Step-by-step explanation:
17>n because 17 is more than n
y = mx + b
y = 2x - 5
you can go to desmos calculator online and simply put in the equation. but what you're going to do is find -5 on the y axis. then you will go up 2 and then 1 to the right.
it should look like this:
