(-8, -5)
To form a rectangle, all the lines must be perpendicular and parallel. If you draw out the points on a coordinate plane then you can find the answer pretty easily.
Also, this one is easy because all the lines are vertical or horizontal, and when that is the case then you can just see which number in the set hasn't appeared twice (1 appeared twice as an <em>x</em> value, 0 appeared twice as a <em>y </em>value, but -8 has only appeared once as an <em>x</em> and -5 has only appeared once as a <em>y </em>value)
so this is how i was taught the inverse function. f(x) is basicly the same thing as saying y
so y=x over x+3
you switch the top x with y so it turns in to x=y over x+3
the problem should tell you what x equals so substitute x with the number it equals and then solve
here is an example f(x)=x over x+3 and x=14
x=y over x+3
14=y over 14+3
the inverse inverse function would probably be just solve the equation so just substitute the number they give you for x in for x
Yes because it goes up and back down
Answer:
= 9
Step-by-step explanation:
We need to find which will make an equivalent fraction statement.
5 x 6 = 30
x 6 = 54 (to find we should do 54 ÷ 6 which = 9)
So:
= 9
hope this helps :)
Answer:
Kelly is 20
Her sister is 14
Step-by-step explanation:
34 ÷ 2 = 17 (average)
17 + 3 = <u>20</u>
17 - 3 = <u>14</u>
