A:4/5
B:-2
C:4
D:5
The 4/5 is the constant of proportionality/unit rate for the proportional relationship.
We have given that,
the unit rate for the proportional relationship is represented by the equation y=4/5x.
We have to determine the unit rate
The equation for proportionality is y = kx, where k is the constant of proportionality.
So in y = 4/5x,
The 4/5 is the constant of proportionality/unit rate for the proportional relationship.

Answer:
A: 4/5
Step-by-step explanation:
The equation for proportionality is y = kx, where k is the constant of proportionality. That is what you're looking for in this question.
So in y = 4/5x, 4/5 is the constant of proportionality/unit rate for the proportional relationship.
Answer:
Frank can park 8.9 hours at the highest
Step-by-step explanation:
Here, we want to know the greatest amount of time that Frank can park given the amount he has to spend on parking.
From the question, we are told that he pays $2 for the hour and an extra $1 per additional hour.
Now, let the number of additional hour he is going to park be x. The bill for the additional hours will be ; $1 * x = $x
By adding this to the initial $2, we have the total $9.90
So, mathematically;
2 + x = 9.90
x = 9.9 -2
x = 7.9 hours
Now, the initial hour he parked is 1 hour + number of incremental hours = 1 + 7.9 = 8.9 hours
day and N represent the number of tops collected on that day.
Based on the situation, John claims the number of tops collected can be modeled by an exponential
function. Riley disagrees and claims the number of tops can be modeled with a linear function. What
is the number of tops collected on the sixth day based on the exponential model? What is the
number of tops collected on the sixth day based on the linear model?
Answer:
Exponential: 64
Linear: 17
Explanation:
I know this is right because I got it wrong and it showed me the answer.
The missing value is 3 because roots of the function f(x) = x2 – 2x – 3 are -1 and 3
Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
We have a function:
f(x) = x² – 2x – 3
Equate the function to zero;
f(x) = 0
x² – 2x – 3 = 0
a = 1, b = -2, c = -3
After simplification:
x = 3 or x = -1
Thus, the missing value is 3 because roots of the function f(x) = x2 – 2x – 3 are -1 and 3

Answer:
63 minutes
Step-by-step explanation:
Set up a ratio equation.
(8 miles/84 minutes should be equal to 6 miles/x amount of minutes). Set the two fractions equal to each other and solve for x by cross multiplying.
Answer: It will take Dan 63 minutes to run 6 miles.
Step-by-step explanation:
= do cross product.
8x = 504
x= 63
