A taxicab company charges $2.10 plus $0.80 per mile. Carmen paid a fare of $11.70. Write and solve an equation to find the number of miles she traveled.

y=0.8x+2.1

x= 12 miles

Step-by-step explanation:

Using the standard charge of 0.8 per mile and a fixed charge of $2.1. Let x represent the miles covered then the expression for coat at any given mile will be y=0.8x+2.1

Substituting $11.7 for y then we can find the valje of x as 11.7=0.8x+2.1

0.8x=11.7-2.1=9.6

X=9.6/0.8=12 miles

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
