Answer:
For every gallon of gas added to the tank, the buyer is charged $2.35
The constant of proportionality of the given equation y = 2.35x will be 2.35.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
Let's x ∝ y
Then x = ky where k will be constant of proportional.
k = x/y which means when two variables are divided which were in proportion it will create a constant proportional.
So,
y /x = 2.35 will be constant of propotional.
Hence "The constant of proportionality of the given equation y = 2.35x will be 2.35".

One end of a spring is attached to a ceiling. When an object of mass m kilogram is attached to the other end of the spring, the spring stretches to a length of / centimeters as shown in the equation l = 24 +3.4m . What is m when l is 73?
please helpppp!
The value of the mass when I is 73 will be m = 14.4.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that when an object of mass m kilogram is attached to the other end of the spring, the spring stretches to a length of / centimeters as shown in the equation l = 24 +3.4m.
The mass will be calculated as below,
73 = 24 + 3.4m
49 = 3.4m
Divide by 3.4 into both sides
14.4 = m

What is the end behavior of the graph?
13x-12x+45•12=14-12x-10•5
Answer:
[tex]x=\frac{576}{11}[/tex]
Step-by-step explanation:
13x - 12x + 45 * 12 = 14 - 12x - 10.5
Multiply first
13x - 12x + 540 = 14 - 12x - 50
Combine like terms
x + 540 = 12x - 36
Subtract x from both sides
540 = 11x - 36
Add -36 to both sides
576 = 11x
Divide both sides by 11
[tex]x=\frac{576}{11}[/tex]

Oth John's parents and Marco's parents decide to start a college fund for their children. The expressions below represent the value of each college fund after w weeks. John's College Fund: 43 w + 1814 12 Marco's College Fund: 25 w + 1744
Answer:
Step-by-step explanation:
The question is not clear on what to solve for, but we can solve for the number of weeks in which the two funds will have the same amount.
let the total fund funds be y
and the number of weeks be w
For John's fund the expression is
y=45w+1814------1
Marco's College Fund
y=25 w+1744---------2
equating 1 and 2 we have
45w+1814=25w+1744
45w-25w=1744-1814
20w=-70
divide both sides by 20 we have
w=-70/20
w=-3.5
this means that in 3 and half weeks the two funds will have the same amount in them

Identify the independent and dependent variables. Then write a rule in function notation for the situation, letting x represent the independent variable.
A concert ticket costs $60.
Answer:
independent: number of tickets purchased;
dependent: total cost;
rule: f(x) = 60x
Step-by-step explanation:
The independent variable is the input of a function (the variable whose value determines the value of the output, or dependent variable). In this case, the independent variable is the number of tickets purchased.
The dependent variable is the output of a function (the variable whose value depends on the value of the input, or independent variable). In this case, the dependent variable is the total cost of all tickets purchased.
The total cost of all tickets purchased is equal to $60 times the number of tickets x. Therefore, a function rule for the total cost of all tickets purchased is f(x) = 60x.

Use the slope formula to find the slope between the given two points?

Answer:
4/3
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
(9-1)/(8-2)
4/3
Answer:
[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
(2,1) (8,9)
The formula that you would use is:
[tex]\frac{y_{2}-{y_1} }{x_2-x_1}[/tex]
So, 2 could be [tex]x_1[/tex] and 1 could be [tex]y_2[/tex]
and 8 could be [tex]x_2[/tex] and 9 could be [tex]y_2[/tex]
When we insert these numbers into the equation, we get:
[tex]\frac{9-1}{8-2}[/tex]
When we solve that we get:
[tex]\frac{8}{6}[/tex]
Now we simplify it by dividing both the numerator and denominator by 2, which would give us:
[tex]\frac{4}{3}[/tex]
