(60,4)(120,8)
slope = (8 - 4) / (120 - 60) = 4/60 = 1/15 <== the constant of proportionality is the slope
Answer:
D
Step-by-step explanation:
-9/2 = -4.5 which is the greatest number from the list
Answer:
=3√5
Step-by-step explanation:
Simplifying this expression involves prime factorisation of
45
45 = 3⋅3⋅5
(3 and 5 are the prime factors of 45)
So √45
=√3⋅3⋅5
=√32⋅5
=3⋅√5
=3√5
