Answer:
B I have that test
Step-by-step explanation:
y = -5x + 11
y = -5x + 19
B. r*12
C. r - 12
D r + 12
r ÷ 12 or r/12
Given the word phrase: the quotient of r and 12.
An algebraic expression for it is
Notes:
The quotient is the ratio of two quantities to be divided or the number obtained by division. Synonyms for the quotient are proportion, ratio, or fractions.
An algebraic expression for the quotient of a and b is
The quotient, a dividend, and a divisor represent the fundamental components of a division equation.
Another example:
A car requires 10 liters of fuel to travel 60 km. Determine the quotient of the distance of the car with fuel (in km/L).
The quotient (or ratio) is
Consider the same method as follows.
This means that the car can travel a distance of 6 km for every 1 L of fuel.
Kilometers per liter is a unit used to measure fuel economy and we see this as one example of the use of the quotient (or ratio).

60 skateboards were sold for maximum revenue.
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Quantity Demanded is inversely related to price as Quantity Demanded increases then price decreases.
Initially,
Q = 50 when P =70
Q = 51 when P=69
Finally, Q=0 when P =120
Q=120 when P=0
Slope = -1
Use the point slope formula
y=mx + b
or Q=-P+b
50= -70+120
b=120
So, Q=-P+120 is the equation for the demand curve
now, Revenue
PQ = P(-P+120) = -P2 + 120P
R' = -2P + 120 and set it equal to zero and solve for P
-2P+120 = 0
2P=120
P = $60
That is the revenue maximizing price plug it into the demand curve equation
Q=-P+120
Q=-60+120
Q = 60
Thus, the number of skateboards sold that maximizes revenue is 60
and, the maximum revenue = 60x60
= $3,600 for a week
