Answer with Step-by-step explanation:
We are given that
Flat fee of taxicab=$7
Cost of one mile=$1.25
1.We have to show that relationship between total cost and the number of miles driven.
2.We have to find independent variable and dependent variable
3.We have to write an equation to model the relationship and make a table to show the cost of 4 to 10 miles.
1.Let x be the number of miles driven by taxicab and total cost y of taxicab.
According to question

This is a relation between number of miles drive and total cost.
2. Independent variable : It is that variable which does not depend on value of another variable .
Dependent variable : it is that variable which depend on value of another variable.
We can see that y depend on x and value of x does not depend on any value.
Therefore, y is dependent variable and x is independent variable.
Substitute x=4 then we get
$12
Substitute x=5 then get
$13.25
\$14.5
$15.75
$17
$18.25
$19.5
Answer:
The y-intercept is 0, which represents the amount of gas used when 0 miles are traveled. The slope is 28, which represents the miles that can be traveled with 1 gallon of gas
Step-by-step explanation:
Let
x----> the amount of gas used in gallons
y ---> the distance traveled in miles
we have

This linear equation represent a direct variation
The y-intercept is the value of y when the value of x is equal to zero
For x=0, y=0
That means ----> The y-intercept is 0, which represents the amount of gas used when 0 miles are traveled
The slope is 
That means ----> The slope is 28, which represents the miles that can be traveled with 1 gallon of gas
Not exactly correct.
y=mx+b Slope is m and y intercept is b.
So, here count the units for the slope. it goes barley to the 7th box. Now, count the units for the y intercept. It goes to the fourth box.
Thus, your equation is y=7x+4
Answer:
I think it’s 240
Step-by-step explanation:
Hope this helps
The three numbers are n, n+1, and n+2.
n + n + 1 + n + 2 = 90
3n + 3 = 90
3n = 87
n = 29
The smallest number is then 29.
n = 29
n + 1 = 30
n + 2 = 31
So the three numbers are 29, 30, and 31. Hope this helps! :)
