asap P varies inversely with x. If P = 7 when x = 8, find the value of P when x = 7.

A. 0.125
B. 1
C. 7
D. 8

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.
