Tristan and his friends are visiting chocolate shops in Salem. They take a cab from one chocolate shop to another one that is 3.6 miles away. What is the distance between the two
chocolate shops on a map with a scale of 2 inches : 0.9 miles?
inches

8 inches

Step-by-step explanation:

Use a proportion.

2 inches is to 0.9 miles as x inches is to 3.6 miles

2/0.9 = x/3.6

0.9x = 2 * 3.6

x = 2 * 4

x = 8

8 inches

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
