What is a function?A function is a relationship between inputs where each input is related to exactly one output.
f(x) = 2x + 2 is a function.
f(x) = 3x + 6 is a function.
We have,
Total amount = $80
Cost of entering the fair = $4
Cost on food = $12
Cost per ride = $1.25
The money left after x rides.
= 80 - (1.25x + 12 + 4)
= 80 - 1.25x - 12 - 4
= 80 - 1.25x - 16
= 64 - 1.25x
= -1.25 + 64
The function to determine money left can be represented as:
f(x) = -1.25x + 64
Thus,
The function that is used to determine how much money he has left over after x rides is
f(x) = -1.25x + 64.

Parallel slope of 8x+y=11
Answer:
The slope parallel to this line is -8.
Step-by-step explanation:
That's because parallel lines have the same slope. Therefore to find the slope of a parallel line, we must first find the slope of this one. On order to do that, we need to solve for y and then look at the coefficient of x.
8x + y = 11
y = -8x + 11
Therefore, we know the slope to be -8, which means the parallel slope must also be -8.

Which monomials are perfect squares? Check all that apply. 6x2 9x8 16x9 25x12 36x16
Answer: Options Third, Second , Fourth are correct.
Step-by-step explanation:
Since we have given that
[tex]6x^2\\\\9x^8\\\\16x^9\\\\25x^{12}\\\\36x^{16}[/tex]
Since we know that
9, 16, 25, 36 are perfect squares.
So, we get that
[tex]9x^8=(3x^4)^2\\\\25x^{12}=(5x^6)^2\\\\36x^{16}=(6x^8)^2[/tex]

In which of these cases is each stamp worth the most?
1. 7 of the same stamp worth a total of $3.15
2. 8 of the same stamp worth a total of $3.20
3. 10 of the same stamp worth a total of $4.10
4. 16 of the same stamp worth a total of $4.80
3.15 /7 = 0.45
3.20/8 = 0.40
4.10/10 = 0.41
4.80/16 = 0.3
Answer is 1. 7 stamps worth 3.15
Answer:
1. 7 stamps for $3.15 → $0.45/stamp
Step-by-step explanation:
Calculate the price per stamp for each scenario:
1)[tex]\frac{3.15}{7}=0.45[/tex]/stamp
2)[tex]\frac{3.20}{8}=0.40[/tex]/stamp
3)[tex]\frac{4.10}{10}=0.41[/tex]/stamp
4)[tex]\frac{4.80}{16}=0.3[/tex]/stamp
Therefore the first scenario of stamps will be the worth the most per stamp, as it has a higher cost than the rest.

Suppose a parabola has vertex (-3,7) and pass throught the point (-2,11). write the equation of the parabola in vertex form.
Parabola is a plane curve with a U shape.
The parabola equation is given as:
y = a (x – h)² + k
The equation of a parabola that has a vertex (-3, 7) and passes through the point (-2, 11) is y = 11.
What is a parabola?Parabola is a plane curve with a U shape.
The parabola equation is given as:
y = a (x – h)² + k
(h, k) is the vertex.
We have,
Parabola:
Vertex = (-3, 7)
Passes through the point = (-2, 11)
The equation of the parabola is y = a (x - h)² + k
(-3, 7) = (h, k)
Since the parabola passes through the point (-2, 11) we get,
11 = a (-2 - (-3))² + 11
11 = a (-2 + 3)² + 11
11 = a x 1 + 11
11 = a + 11
Subtract 11 on both sides.
0 = a
a = 0
Now,
y = 0 (x + 3)² + 11
y = 0 + 11
y = 11
Thus,
The equation of a parabola that has a vertex (-3, 7) and passes through the point (-2, 11) is y = 11.

What sum or difference is equivalent to the following expression 5-3x/5 A 1+3/5 B 1+3x/5 C 1-3x/5 D 25-15x
Answer:
Option C is the answer.
Step-by-step explanation:
The given expression is [tex]\frac{(5-3x)}{5}[/tex]
We solve it further to get the simplified form.
[tex]\frac{(5-3x)}{5}[/tex] = [tex]\frac{5}{5}-\frac{3x}{5}[/tex]

help will mark brainliest Jim Shu has the following work shown on their paper. The directions read “Simplify each radical.” Unfortunately, they have not simplified correctly.
A. Find their mistake and explain what they did wrong.
Jim Shu made two mistakes in simplifying radicals: they missed the initial steps and included an irrelevant step of checking the answer's reasonability.
Explanation:The instructions provided to Jim Shu involve simplifying radicals, but there is an omission of the initial steps in the process.
The student proceeds with step 6 without detailing the necessary earlier steps in simplifying the algebraic expression.
This misstep results in an incomplete representation of the solution process.
Furthermore, step 7 introduces an unrelated directive, advising the student to check the answer for reasonability.
This step is incongruent with the task at hand, which is the simplification of radicals.
To address this error, Jim Shu should incorporate the essential preliminary steps for simplifying radicals, ensuring a comprehensive presentation.
Additionally, the extraneous step of checking reasonability should be omitted, aligning the solution process with the given directions.
a fishing lake was stocked with 300 bass. Each year, the population decreases by 25. the population of bass in the lake after x years is represented by the function f(x)=300-25x
The function f(x)=300-25x represents the decline of population in a fishing lake that was initially stocked with 300 bass. Each year, the population reduces by 25. For instance, after 4 years, the number of bass left in the lake would be 200.
Explanation:The question is about a fishing lake that was initially stocked with 300 bass. As per the information given, the population of bass in the lake decreases by 25 each year. Therefore, if we let x represent the number of years, then every year, the number of bass decreases by 25x. This relationship is represented by the algebraic function f(x)=300-25x.
To provide a practical understanding, suppose you want to calculate the number of bass remaining after 4 years. You just substitute '4' in place of x in the equation. Hence, f(4) = 300 - 25 * 4 = 300 - 100 = 200. So, after 4 years, there would be 200 bass remaining in the lake.
