Answer:
Third table
Step-by-step explanation:
For the relationship to be proportional
y/x = constant
First table y/x = 8/4 = 2 then 7/11 doesn't =2 so it is not
Second table y/x =52/5 = 5 then 49/7 doesn't =5 so it is not
Third table y/x = 3/6=1/2 then 5/10 = 1/2 then 7/14 = 1/2 it is proportional
Last table y/x = 6/3 = 2 then 11/8 doesn't =2 so it is not
Answer:
b
Step-by-step explanation:
Answer: 729
Step-by-step explanation:
3^-2 = 1/9
3^-4 = 1/81
(-1)^2 = 1
1/(1/9 * 1/81 * 1)
1/ 1/729 = 729
Answer:
f(-2) = 14
Step-by-step explanation:
f(x) = 3x^2 - x
f(-2) = 3(-2)^2 - (-2)
= 3(4) + 2
=12 + 2
= 14
Answer:5x + y = -11
Step-by-step explanation:
