13x - y = 19
-y = - 13x + 19
y = 13x + 19
The question is find the equation, in the function and standard notations, that represent the amount spent in the range of 0 to 5 rides.
Constant cost: $30
Independent variable, number of rides: r
Variable cost: $2r
Total spend, s(r): 30 + 2r
Function: s(r) = 30 + 2r, for 0 ≤r ≤ 5 ----- this is the function notation
Standard form: s(r) is the dependent variable = s
s = 30 + 2r => s - 2r = 30 =>
s + (-2)r = 30, for 0 ≤ r ≤ 5 ------ this is the standard form

Answer:
Jen needs approximately 8 tiles to cover the kitchen floor
Step-by-step explanation:
What we want to calculate here is the number of tiles needed to cover the kitchen floor.
The first thing we need to do here is to calculate the area of the kitchen floor.
Mathematically, that would be the product of the length of the kitchen floor and the length of the width.
That is; 4 5/6 * 5 = 29/6 * 5 = 145/6 m^2
Now, to calculate the number of tiles needed, we only need to divide the area of the kitchen floor by the area of the individual tiles
Mathematically, that would be;
145/6 ÷ 3 = 145/6 * 1/3 = 145/18 = 8.05556
This is approximately 8 tiles
One and four hundred thirteen thousandths in standard form would be <u>1.413 x 10^0.</u>
