Greetings!
The y-intercept denotes the place where the red line crosses the y-coordinate.
Y= the vertical axis
X= the horizontal axis
(If you look closely you will see that the axes are labeled x & y)
So where that ol red line cross the y-axis?
Hint: it's a number between 2 & 4 :)
When you write the answer be sure to put it in fancy coordinates notation, e.g.:
(0,x)
Where x is the value where the red line crosses, and 0 is the x-axis value (since the red line doesn't cross the x-axis where it crosses the y-axis.
Whew, how many times can I write the word "axis" before it starts to look funny?
Anyway, hope that helps dear lad or lassie.
Carry on! You got this!
Answer: f(x) = 0.30x + 2.50
This is the same as writing y = 0.30x + 2.50
========================================================
Explanation:
x = number of pounds
y = f(x) = total cost in dollars
1 pound costs $0.30
x pounds cost 0.30x
This is ignoring the entrance fee
Tacking on the entrance fee leads to a total of y = 0.30x + 2.50
------------------
The independent variable is always x and the dependent variable is always y.
The independent variable (number of pounds) determines what the dependent variable (total cost) will be.
Answer:
A
Step-by-step explanation:
You convert each fraction to have the same decimal to find the LCD of both denominators
4, 8, 12, 16, 20 and 5, 10, 15, 20 = both of them have 20 in common
You multiply the numerator and denominator by 5 for 2 3/4 and for 5 4/5 you multiply both the numerator and denominator by 4
2 15/20 and 5 16/20
Subtract them and their is your answer
