4x represents the hours and A, B, and C doesn't make sense especially c because it has a -4 so the correct answer is D I'm sure
Answer:
Choice D y = 4x -12
Step-by-step explanation:
Since Kevin owes his brother $12, we can clarify that b=-12. He also has a babysitting job where he receives $4 an hour which we can express as 4x; let x represent the amount of hours he works.
The graph equation is y=mx + b
so, y = 4x -12

An open box is made by cutting squares from the corners of a piece of
metal that is 16 inches by
20 inches, as shown in the figure. The edge of each cut-out square is x inches. Find V(x), the
volume of the box in terms of x.
Answer:
The volume of the box is
V(x) = 4x^3 -72x^2+320x
Step-by-step explanation:
Here, we are interested in calculating the volume of the box
From what we can see, the shape of the box is a cuboid
Mathematically, the volume of a cuboid is l * b * h
Thus, what we have will be;
x * 20-2x * 16-2x
= x ( 20(16-2x) -2x(16-2x))
= x(320-40x-32x + 4x ^2)
= x(320-72x+4x^2)
= 320x-72x^2 + 4x^3
the volume v(x) will be;
V(x) = 4x^3 -72x^2+320x

Kasey is trying to run a certain number of miles by the end of the month. If Kasey is 60% of the way to achieving her goal and she has already run 24 miles, how many miles is she trying to run by the end of the month?
Answer:
40 miles
Step-by-step explanation:
Step one:
given data
let the total distance to be covered by Kasey by the end of the month be x
Required is x
so
60% of x= 24
60/100*x= 24
0.6x= 24
divide both sides by 0.6
x= 24/0.6
x=40 miles
The number of students who bring lunch is 45 fewer these the number of students who eat the school lunch. There are more than 485 students who bring lunch. Write an inequality to find the possible number of students,n, who eat the lunch
Answer:
83
Step-by-step explanation:
there is many ways to do it!! HOPE YOU ACE IT
The number of students, n that possibly eat lunch at school, n = 531 or more students.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that the number of students who bring lunch is 45 fewer these the number of students who eat the school lunch. There are more than 485 students who bring lunch.
The number of students who bring lunch, is;
B > 485 students
The number of student who eat lunch in school, E = B + 45
Thus, E > 485 + 45
The number of student that possibly eat lunch in school, E > 530 students.
The number of students, n that possibly eat lunch at school, n = 531 or more students.

a family of six goes to the local sandwich shop. all six people order the combination meal, which includes a drink and a sandwich for 6.99. one person thinks the total bill for the family of six will be around 30.00.
is this a reasonable estimate?
Answer:
No it wouldn’t be
Step-by-step explanation:
Well lets say the cost of 6.99 is rounded up to 7 since its a penny short.
There are 6 people and 6*7=42
So the answer would be about 42 dollars which is 12 dollars off.
Even if we round down the 6.99 to 6 it would still be 6 dollars off and thats still a low estimate
Peter is thinking of playing the StarOne lottery. When he buys a ticket, he has to pick a single letter from A to Z and a single digit from 0 to 9. He can win $700 if both his letter and the digit match the letter and digit picked on that day. StarOne costs $3 per ticket.
What is the expected value per turn for Star One?
Based on the single letter that Peter picks and the single digit, the expected value in one turn for Star One is $-0.296262
How to find the expected value?First, find the probability that Peter picks the correct letter and the correct digit:
= Probability of picking letter x Probability of picking digit
= 1/26 x 1/10
= 0.3846%
The expected value per turn for Star One s:
= (0.3846% x 700) + ( (1 - 0. 3846%) x -3)
= $-0.296262
In conclusion, the expected value for a turn of Star One is $-0.296262.

The surface area of a cylinder aluminum can is a measure of how much aluminum the can requires. If the can has radius r and height h, its surface area A and its volume V are given by the equations: A= 2πr^2 + 2πrh and V=πr^2h
a) The volume V of a 12 oz cola can is 355 cm^3. A cola can is approximately cylindrical. Express its surface area A as a function of its radius r, where r is measured in centimeters. [hint: first solve for h in terms of r.]
PLEASE HELP FAST
The required surface area would be A= 2πr² + 710/r which represents area A as a function of its radius r, where r is measured in centimeters.
The can's surface area A and volume V are determined by the equation if the container has a radius of r and a height of h.
A= 2πr² + 2πrh and V = πr²h
The volume V of a 12 oz cola can is 355 cm³
Given that cola can is approximately cylindrical.
V = πr²h = 355 cm³
h = 355 / πr²
Substitute the value of h in the can's surface area A, we get
A= 2πr² + 2πr(355 / πr²)
A= 2πr² + 2(355/r)
A= 2πr² + 710/r
Therefore, the required surface area would be A= 2πr² + 710/r which represents area A as a function of its radius r, where r is measured in centimeters.

Answer:
3. The vertex form of the function, f(x) = x² - 4·x - 17 is f(x) = (x - 2)² - 21
4. The solutions are, x = -2 + √10 and x = -2 - √10
5. The quadratic equation with vertex (3, 1) and a = 1 in standard form is given as follows;
f(x) = x² - 6·x + 10
Step-by-step explanation:
3. The function given in standard form is f(x) = x² - 4·x - 17, which is the form, f(x) = a·x² + b·x + c
The vertex form of the of a quadratic function can be presented based on the above standard form as follows;
f(x) = a(x - h)² + k
Where;
(h, k) = The coordinate of the vertex
h = -b/2a
k = f(h)
Comparing with the given equation, we have;
f(x) = a·x² + b·x + c = x² - 4·x - 17
a = 1
b = -4
c = -17
∴ h = -(-4)/(2 × 1) = 2
h = 2
k = f(h) = f(2) = 2² - 4 × 2 - 17 = -21
k = -21
The vertex form of the function, f(x) = x² - 4·x - 17 is therefore, given as follows;
f(x) = (x - 2)² - 21
4. The given equation for which we need to solve by completing the square is 2·x² + 8·x = 12
Dividing the given equation by 2 gives;
x² + 4·x = 6
Which is of the form, x² + b·x = c
Where;
a = 1
b = 4
c = 6
From which we add (b/2)² to both sides to get x² + b·x + (b/2)² = c + (b/2)²
Adding (b/2)² = (4/2)² to both sides of x² + 4·x = 6 gives;
x² + 4·x + 4 = 6 + 4
(x + 2)² = 10
x + 2 = ±√10
x = -2 ± √10
The solution are, x = -2 + √10 and x = -2 - √10
5. Given that the value of the vertex = (3, 1), and a = 1, we have;
The vertex, (h, k) = (3, 1)
h = 3, k = 1
Therefore, h = 3 = -b/(2 × a) = -b/(2 × 1)
∴ -b = 2 × 3 = 6
b = -6
k = f(h) = a·h² + b·h + c, by substitution, we have;
k = f(3) = 1 × 3² + (-6) × 3 + c = 1
∴ c = 1 - (1 × 3² + (-6) × 3) = 10
c = 10
The quadratic equation with vertex (3, 1) and a = 1 in standard form, f(x) a·x² + b·x + c is therefor;
f(x) = x² - 6·x + 10
