the time is takes to mow the lawn at a large park m(x) varies inversely with the numbers of workers assigned to the job x. it takes 90 minutes to complete the job when 3 workers are assigned to it.
which equation can be used to find the time to complete the job when x workers are assigned to it?
a.) m(x)= 270/x
b.) m(x) = 270x
c.) m(x) = 30/x
d.) m(x) = 30x
2. suppose that h(x) varies inversely with x and h(x)=50 when x =0.25
what is h(x) when x =2?
a.) 0.5
b.) 6.25
c.) 12.5
d.) 24
can you also provide how you got the answer as well : )

  or  

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
