Answer: 3
Step-by-step explanation:
To find the slope you have to divide y over x: y/x or most commonly known as rise/run.
We start at the point where the line is touching a point, in this case it's -8 in the y axis.
Then we count up until we find another point that the blue line is touching. In this case at the coordinates (2, -2). So there's 6 values up from -8 and we have to move to the right 2 values to reach the point the blue line is touching.
So we use the formula rise/run or y/x:
6/2 = 3
This is very hard to explain in just text! I hope you understand

The volumes of the cylinder and cone are calculated using a radius r to give;
The volume of the cylinder and cone combined is (8/3)•π•r³ How can the volumes of the solid figures be calculated?The radius of cylinder = r
Height of the cylinder = 2•r
Radius of cone = r
Height of the cone = 2•r
Volume of the cylinder, Vc = π•r²•(2•r) = 2•π•r³
Volume of the cone, Vco == (1/3)•π•r²•(2•r)
Which gives; Vco == (2/3)•π•r³

Given that f(x)=2x^2-4x+5 determine if the graph is a maximum or minimum
Answers
The graph of f(x) = 2x^2 - 4x + 5 is a minimum
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to determine if the graph is a maximum or minimum?The equation of the function is given as
f(x) = 2x^2 - 4x + 5
The above equation is a quadratic equation.
A quadratic equation is represented as:
f(x) = ax^2 + bx + c
By comparison, we have
a = 2
b =-4
c = 5
If the value of a is positive, the graph is a maximum.
Since the value of a is 2, then it means that the graph is a minimum
Hence, the graph of f(x) = 2x^2 - 4x + 5 is a minimum

Answers
Based on the start-up expenses to the sole proprietorship, the amortization amount reported as an "other expense" on Schedule C (Form 1040) for the first year of business will be $111.
What is the amortization amount?Before the amortization amount can be calculated, a deduction of $5,000 should be made because the start-up costs were less than $50,000.
The amount to be amortized is therefore:
= 7,500 - 5,000
= $2,500
The amount to be amortized will be amortized over 15 years. As the business started on May 1, 2021, there are only 8 months left in the year.
The amortization amount is:
= (2,500 x 8 months) / ( 15 x 12 months a year)
= $111

13 Aura 30% increase the new price of a book is $91.00. What was the original price of the book?
Answers
The old/Original value of the book before 30% increase in price is $70
Let us assume the old price of book before30% increase be x
Then the new price of the book after 30% increase would be x+ 30% of x
Which can be simplified as x+ 0.30x
Which further can be simplified 1.30x
As we are provided with the new price of book, we have to equate the above linear equation with the new price of the book
1.30x = $91
To solve the equation we need to move 1.30 from left hand side to right hand side which would change from to
X= 91/1.30
X=$70
Hence the old value of the book before 30% increase in price is $70
Correct question is if 30% increase in price of a book and the new price of a book is $91.00. What was the original price of the book?

-2(y + 1) + 5y = 3(y + 1) - 2
solve for y
Answers
Answer:
0 = 3 or No Solution
Step-by-step explanation:
a) Simplify both sides of the equation
−2(y + 1) + 5y = 3(y + 1) − 2
(−2)(y) + (−2)(1) + 5y = (3)(y) + (3)(1) + −2
−2y + −2 + 5y = 3y + 3 + −2
(−2y + 5y) + (−2) = (3y) + (3 + −2)
3y + −2 = 3y + 1
3y −2 = 3y + 1
b) Subtract 3y from both sides
3y − 2 − 3y = 3y + 1 − 3y
−2 = 1
c) Add 2 to both sides
−2 + 2 = 1 + 2
0 = 3 or No Solution

What is relations in Mathematics?The relation in mathematics refers to the relationship between two or more types of values. Assume that x1 and x2 are two ordered pair sets. If set x is related to set y, the values of set x are referred to as domain, whereas the numbers of set y are referred to as range.
What exactly is a fundamental relationship?A base relation is simply a physical table that is maintained in a database. In contrast, a view is formed from base relations but it doesn't physically exist in the database; it only exists as either a structural definition that pulls data from a number of different base relations.
According to the given data:Given : 5 daises to 2 roses

Encontrando un factor comun entre los 3 números dados, concluimos que cada pedazo de tronco debe medir 3 metros, y se obtendran 10 pedazos en total.
¿cuánto deben medir los pedazos de tronco si tienen que ser del mismo tamaño?Sabemos que los troncos miden 15, 9, y 6 metros, si los queremos cortar en pedazos de igual longitud, de tal forma que nada se desperdicie, entonces debemos encontrar un factor comun entre esos 3 numeros.
Los podemos reescribir como:
15 = 3*5
9 = 3*3
6 = 2*3
Entonces el unico factor comun entre las 3 longitudes es 3.
El tronco de 15 metros dará:
15/3 = 5 pedazos de tronco.
El tronco de 9 metros dará:
9/3 = 3 pedazos de tronco.
El tronco de 6 metros dará:
6/3 = 2 pedazos de tronco.
Sumando eso obtenemos 5 + 3 + 2 = 10 pedazos en total.

10. The slope is the monthly payment on the loan
How can a straight line equation be analyzed?6. The points on the graph in question 6 are; (0, 4), and (4, 2)
The slope is given by the ratio of the rise to the run of the graph as follows;
[tex]Slope = \frac{2 - 4}{0 - 4} = - 0.5[/tex]
The slope of the graph is -0.57. The equation in slope and intercept form is found as follows;
The given points are;
(-1, 3), and (-3, 1)
The slope and intercept form is presented as follows;
y = m•x + c
The point and slope form is presented as follows;
y - y1 = m•(x - x1)
Where m is the slope of the graph
m = (1 - 3)/(-3 - (-1)) = -2/-2 = 1
Which gives;
y - 3 = 1 × (x - (-1)) = x + 1
y = x + 1 + 3 = x + 4
y = x + 4The equation of the graph in slope and intercept form is; y = x + 4
8. The points are; (-4, 8), (4, 6)
Which gives;
m = (6 - 8)/(4 - (-4)) = -2/8 = -0.25
Therefore;
y - 8 = -0.25•(x - (-4)) = -0.25•x - 1
y = -0.25•x - 1 + 8 = -0.25•x + 7
y = 7 - 0.25•x9. The amount Zachary purchased the computer on loan = $1,800
The balance after 3 months = $1,350
The balance after 5 months = $1,050
Therefore;
The points on the graph of the equation that models the balance are therefore;
(0, 1,800), (3, 1,350), (5, 1,050)
Which gives;
B - 1800 = ((1,350-1,800)/(3-0))•(m - 0)
B - 1800 = -150•m
B = 1,800 - 150•mThe equation that models the balance, B, after m months is therefore;
B = 1,800 - 150•m10. The slope, ((1,350-1,800)/(3-0)) = -150, signifies the amount by which the balance reduces each month, which is the same as the amount Zachary pays each month, (the monthly payment).

An employment agency specializing in temporary construction help pays heavy equipment operators $136 per day and general laborers $80 per day. If thirty-two people were hired and the payroll was $3960, how many heavy equipment operators were employed? How many laborers?
Answers
The number of heavy equipment operators employed is 26 while number of laborers employed is 6
How to solve Algebraic word problems?
Let x be the number of heavy equipment operators employed
Thus, If thirty-two people were hired, then we can say that;
32 - x represents the number of laborers employed
Thus, the equation to solve for x would be;
136x + 80(32 - x) = 3960
136x + 2560 - 80x = 3960
216x + 2560 = 3960
216x = 3960 - 2560
216x = 1400
x = 1400/216
x ≅ 6
Thus;
32 - x = 32 - 6 = 26
Thus, we conclude that number of heavy equipment operators employed is 26 while number of laborers employed = 6
