The statement "Samuel will get 25 or more for mowing the lawn" can be represented using the inequality → x ≥ 25 and the graph number [2] represents the correct graph.
What is an inequality?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. There are two types of inequalities namely strict and slack inequalities.
Given is the following statement - "Samuel will get 25 or more for mowing the lawn".
The given statement is -
Samuel will get $25 or more for mowing the lawn.
Assume that Samuel gets $x for mowing the lawn.
Then according to the question, we can write the inequality as -
x ≥ 25
" ≥ " sign to represent either 25 or more.
So, the inequality can be written as x ≥ 25 and the graph number [2] represents the correct graph.
Therefore, the statement "Samuel will get 25 or more for mowing the lawn" can be represented using the inequality → x ≥ 25 and the graph number [2] represents the correct graph.

Find the surface area of a cylinder with a height of 7 in and a base diameter of 8 in.
Use the value 3.14 for pi and do not do any rounding.
Be sure to include the correct unit.
Answers
The total surface area of the cylinder whose height is 7 units and diameter is 8 units is 226.08 units.
What is surface area?
The surface area of a solid item is a measurement of the total volume that the surface of the thing occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more complicated than the definition of arc length for one-dimensional curves or the definition of surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is equal to the sum of the areas of its faces. When smooth surfaces, like spheres, are represented as parametric surfaces, their surface area can be calculated. This definition of surface area, based on infinitesimal calculus methods, uses partial derivatives and double integration.
The formula to calculate the total surface area of a cylinder is:
[tex]S = 2\pi rh + \pi r^2[/tex]
Where, S = surface area, r = radius, and h = height
As given in the question,
height (h) = 7 units
diameter (d) = 8 units
Since, r = d/2
So, r = 8/2 = 4 units
putting these values in the formula:
[tex]S = (2\times 3.14 \times 4 \times 7)+( 3.14 \times 4^2)[/tex]
[tex]S = (2\times 3.14 \times 4 \times 7)+( 3.14 \times 16)[/tex]
[tex]S = 175.84 + 50.24\\[/tex]
S = 226.08 units
Therefore, Surface area of the cylinder is 226.08 units

Simplify completely (7x²+11x-6)/(7x²-10x+3)
Answers
One way of simplifying the given expression is by factoring them, and then simplifying the common terms.
So, we need to write:
[tex]\begin{gathered} 7x^{2}+11x-6=7(x-a)(x-b) \\ \text{and} \\ 7x^{2}-10x+3=7(x-c)(x-d) \end{gathered}[/tex]The constants a and b are the zeros of the first expression, and the constants c and d are the zeros of the second expression.
So, we can find those zeros using the quadratic formula. We obtain, for the first expression:
[tex]\begin{gathered} x=\frac{-11\pm\sqrt[]{11^{2}-4(7)(-6)}}{2(7)} \\ \\ x=\frac{-11\pm\sqrt[]{289}}{14} \\ \\ x=\frac{-11\pm17}{14} \\ \\ a=\frac{-11-17}{14}=-2 \\ \\ b=\frac{-11+17}{14}=\frac{6}{14}=\frac{3}{7} \end{gathered}[/tex]And, for the second expression, we obtain:
[tex]\begin{gathered} x=\frac{-(-10)\pm\sqrt[]{(-10)^{2}-4(7)(3)}}{2(7)} \\ \\ x=\frac{10\pm\sqrt[]{16}}{14} \\ \\ x=\frac{10\pm4}{14} \\ \\ c=\frac{10-4}{14}=\frac{6}{14}=\frac{3}{7} \\ \\ d=\frac{10+4}{14}=1 \end{gathered}[/tex]Then, we can write:
[tex]\begin{gathered} 7x^2+11x-6=7(x-(-2))(x-\frac{3}{7})=7(x+2)(x-\frac{3}{7}) \\ \\ 7x^2-10x+3=7(x-\frac{3}{7})(x-1) \end{gathered}[/tex]Thus, the given function can be simplified as follows:
[tex]\frac{7x²+11x-6}{7x²-10x+3}=\frac{7(x+2)(x-\frac{3}{7})}{7(x-\frac{3}{7})(x-1)}=\frac{x+2}{x-1}[/tex]Therefore, the answer is:

How do you know when an equation has one solution? A. The coefficients are differentB. The coefficients are the same and the constants are differentC. The coefficients are the same and the constants are same
Answers
SOLUTION
Given the question in the question tab, the following are the solution steps to answer the question.
STEP 1: Define an equation with one solution
You can tell that an equation has one solution if you solve the equation and get a variable equal to a number. A system of linear equations has one solution when the graphs intersect at a point.
STEP 2: Examine the options
An equation is said to have "no solution" when the coefficients are the same and the constants are different as seen below:
[tex]\begin{gathered} 4x+12=24+4x \\ 4x-4x=24-12 \\ 0=12 \end{gathered}[/tex]When the coefficients are the same and the constants are the same, the equation is said to have "infinitely many solutions as seen below:
[tex]\begin{gathered} 4x-14=-6-8+4x \\ 4x-14=-14+4x \\ 4x-4x=-14+14 \\ 0=0 \end{gathered}[/tex]When the coefficients are different, the equation is said to have one solution as seen below:
[tex]\begin{gathered} 2x+56=3x-12 \\ 2x-3x=-12-56 \\ -x=-68 \\ x=68 \end{gathered}[/tex]Hence, the answer is:
"When the coefficients are different"

There are infinitely many solutions
Explanation:
Given the system of linear equations:
[tex]\mleft\{\begin{aligned}6x-30y=18 \\ 5x+25y=15\end{aligned}\mright.[/tex]To solve using Matrices, we write the equation in the form:
Ax = b
Where A represent the matrix of the coefficient of the variables x and y
x represent the matrix of the variables x and y
and b represents the matrix of the constants on the right hand side.
In matrix form, we have:
[tex]\begin{bmatrix}{6} & {-30} \\ {5} & {-25}\end{bmatrix}\begin{bmatrix}{x} \\ {y}\end{bmatrix}=\begin{bmatrix}{18} \\ {15}\end{bmatrix}[/tex]We must have a nonzero determinant for A
The determinant of A is:

How to find the quadratic equation associated with given real roots and leading coefficient
In this problem we must determine the quadratic equation such that its roots are √3 + 1 / 2 and √3 - 1 / 2 and whose leading coefficient is equal to 9. This can be found by substituting on factor form:
y = a · (x - r₁) · (x - r₂)
Where:
a - Leading coefficient.r₁, r₂ - RootsIf we know that r₁ = √3 + 1 / 2, r₂ = √3 - 1 / 2 and a = 9, then the quadratic equation is:
y = 9 · (x - √3 - 1 / 2) · (x - √3 + 1 / 2)
y = 9 · [x² - (√3 - 1 / 2) · x - (√3 + 1 / 2) · x + 3 - 1 / 4]
y = 9 · (x² - 2√3 · x + 11 / 4)
y = 9 · x² - 18√3 · x + 99 / 4
The quadratic equation is y = 9 · x² - 18√3 · x + 99 / 4.

Together, Nora and Addison own 152 shares of stock. Nora has 4 less than three times Addison's amount. How many shares does each girl have?
Answers
The number of shares that Nora has is 113.
The number of shares that Addison has is 39.
How many shares do they have?Let x represent the amount of shares that Addison has
Shares that Nora has = 3x - 4
The sum of shares they both have : 3x - 4 + x = 152
In order to determine the value of x, take the following steps:
Combine similar terms together: 3x + x = 152 + 4
Add similar terms: 4x = 156
Divide both sides by 4 : x = 156/ 4 = 39
Shares that Nora has = 3(39) - 4

The distance between the two given points X(-3,3) and Z(4,4) in the given cartesian plane is XZ = √50 = 7.07 units.
As per the question statement, we are supposed to calculate the distance between the two given points X(-3,3) and Z(4,4) in the given cartesian plane. We know that the distance between any two points in the plane is given by:
d=√((x2 – x1)² + (y2 – y1)²), where "d" is the distance between the points (x1,y1) and (x2,y2). Using this formula to find the distance between the two given points X(-3,3) and Z(4,4).
XZ = √((4 +3)² + (4 – 3)²)
XZ = √((7)²+ (1)²)
XZ = √(50)
XZ = 7.07 units
