0.6 is 6 tenths. 6/10 is the fraction form but you have to simplify so it becomes 3/5.
A. This is a function because there is one x value for every y value. Basically, that means every x is different, there are no repeating x's. A function can have repeating y values, just not the x ones.
B.
table : when x = 4...u already have that point (4,9)...so this value is 9.
relation :
f(x) = 2x - 8...when x = 4
f(4) = 2(4) - 8
f(4) = 8 - 8
f(4) = 0
so the greater values goes to the table....with a value of 9 <==
C. f(x) = 34
f(x) = 2x - 8
34 = 2x - 8
34 + 8 = 2x
42 = 2x
21 = x <==
300 miles divided by 6 hours is a rate question. So the answer would be 50 miles per hour
Y= 2
every time y goes up it goes up by 2
-1+2=1
1+2=3
3+2=5
