Erica is entering a bicycle race for charity. Her mother will donate $0.40 for every 0.25 mile she bikes. If Erica bikes 18 miles, how much will her mother donate

Erica's Mother will donate $28.8

Step-by-step explanation:

As you can see we need to find out the amount of money her mother will donate if she bikes 18 miles so to figure that out we will need to divide the amount of miles by 0.25 that will give us 72. Now since we need to figure out how much money her mother will donate we need to multiply 72 by 0.40 that will give us 28.8.

Ps. ur welcome and if i'm wrong sowwy *0*

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.

step-by-step explanation:

part a: 1.08

part b: 27.59
