Answer:
Step-by-step explanation:
#1 - Positive,
#2 - No relationship.
#3 - Negative
The variable m should equal -5
It has been given that y varies inversely with x, therefore the equation for this relationship is as follows;
y =

\
when y = -18 and x = 6
-18 = k/ 6 ---1)
We need to find x when y = 5
5 = k/x
when we divide 1)/2), k gets cancelled

x = -18*6/5
x = -21.6
when y = 5, then x = -21.6
Answer:
(x + 9)(x - 8)
Step-by-step explanation:
f(x) = x^2 + x - 72
= x^2 - 8x + 9x - 72
= (x^2 - 8x) + (9x - 72)
= x(x - 8) + 9(x - 8)
= (x + 9)(x - 8)
