Answer: \(2\left(x-\frac{1}{4} \right)^{2}\)

Step-by-step explanation:

\(2x^{2}-x+\frac{1}{8}\\\\=2\left(x^{2}-\frac{1}{2}x \right)+\frac{1}{8}\\\\=2\left(\left(x-\frac{1}{4} \right)^{2}-\frac{1}{16} \right)+\frac{1}{8}\\\\=2\left(x-\frac{1}{4} \right)^{2}-\frac{1}{8}+\frac{1}{8}\\\\=\boxed{2\left(x-\frac{1}{4} \right)^{2}}\)

This shows that 76 cookies will be made with the total pounds of cookies

Fractions are written as a ratio of two integers. Given the following parameters

Total pounds of cookies made = 4 3/4 pounds

Total pounds of cookies made = 19/4 pounds

If he uses 1/16 pound of dough for each cookie, the total amount of cookies made is given;

Number of cookies = 19/4 ÷ 1/16

Number of cookies = 19/4 * 16/1

Number of cookies = 19 * 4

Number of cookies = 76

This shows that 76 cookies will be made with the total pounds of cookies

Based on the number of shares outstanding and the market value, the price the stock is currently selling for is  $31.40

To find the selling price of the stock the formula is:

= Equity value of stock / Number of stock outstanding

The number of stock outstanding is 19,000 shares. The equity value of the stock is $596,600.

The selling price of the stock today then is:

= Equity value of stock / Number of stock outstanding

= 569,600 / 19,000

= $31.40

The linear function with the greatest y-intercept on a coordinate plane is y = 3x+4

An intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.

if y = mx + c it means c is the y intercept

compare the equations

for y = 6x+ 1, c = 1 so the y-intercept is 1

for the line that passes through (0,2) and (5,0) the y -intercept is actually the value of y when x is 0 which is 2

for the line that passes though (1,2) (0,-3) the y-intercept is -3

for y = 3x + 4, the y-intercept is 4.

So the function with the greatest y-intercept is y = 3x + 4

In conclusion y = 3x + 4 is the function with the greatest y-intercept.

A path between two classrooms that takes no longer than 15 minutes and maximizes the amount of shade cover.

This problem can be solved using a Shortest Path Algorithm, which is a type of algorithm that finds the shortest path between two nodes in a graph. To solve this problem, reasonable assumptions to make include: the walking speed is constant, the walking path is a straight line, and the amount of shade cover is quantifiable.

The algorithm can be modeled using a weighted graph, where the nodes are the university classrooms, and the edges are the paths between them. The weights of the edges represent the length of the path in terms of time, and the amount of shade cover. The algorithm will then search through the graph, finding a path between the two nodes that optimizes the amount of shade cover while still maintaining a total path length of no more than 15 minutes.

The algorithm can then be implemented using two loops. The outer loop will iterate through each of the nodes and the inner loop will iterate through each of the edges connecting the nodes. For each iteration, the algorithm will check if the total path length is less than 15 minutes and if the amount of shade cover is greater than the current best path. If both conditions are met, the algorithm will save the path as the best path and update the current best path length and shade cover

By using this algorithm, we can find a path between two classrooms that takes no longer than 15 minutes and maximizes the amount of shade cover.

Since the two angles marked are corresponding, if \(p\) and \(q\) are parallel, they must be equal.

Therefore, we have:

\(14x+18=116,\\14x=98,\\x=\boxed{7}\)

The resulting rational number is √100

Rational numbers:

A rational number is a number that can be represented a/b where a and b are integers and b is not equal to 0.

Given,

Here we have the following list of numbers

√75, -√25, 2√7, √100, √0.36, √0.0144, √3/7 , -√36/49

Now, we need to identify whether these are the rational numbers or not.

AS per the definition of rational number,

When we take the  root for the value √75, we get 8.660 that is a non-whole square root, 8.660 is not a rational number.

The value -√25 takes the negative value so it is not a rational number.

The number 2√7, this one also produce on-whole square root, so this one is not a rational number.

The value of √100 is 10, and it is a rational number.

The value of √0.36 is 0.6 which is less than 0, so it is not a rational number.

The value of √0.0144 is 0.012 which is less than 0, so it is not a rational number.

The value of √3/7 this one also produce on-whole square root, so this one is not a rational number.

The value -√36/49 takes the negative value so it is not a rational number.

Therefore, the rational number is √100.

Step-by-step explanation:

Factor out what all terms have in common

The point slope form of the given slope intercept form is:

y ₋ 9 = ₋1/3 (x ₋ 0)

Given, we have the slope intercept form as :

y = ₋1/3x ₊ 9

To convert the given form into point slope form we first need to determine the slope and the point.

A straight line is represented as a point on the line and its slope in point slope form. That means using the point slope form, one may find the equation of a line passing through the points (x ₁, y ₁) and having a slope of "m".

from the given equation y = ₋1/3x ₊ 9

the above equation is in the form of: y = mx ₊ b

slope (m) = ₋1/3

y intercept (b) = 9

x intercept = 0

Therefore, the points are: (0,9) = (x₁ , y₁)

hence the point slope form is:

y - y₁ = m(x ₋ x₁)

y ₋ 9 = -1/3(x ₋ 0)

hence we get the required point slope form.

Answer:

A) One solution

B) No solution

C) Infinite number of solutions

D) One solution

E) Infinite number of solutions

Step-by-step explanation:

There are 5 equations to solve:

A) - 4 x + 6 + 3 x = -12

combining like terms and solving for x gives:

- x + 6 = - 12

- x = -18

x = 18

which is a unique (ONE) solution

B)  5 (2 x - 2) = 10 x + 10

distributive property gives us:  10 x - 10 = 10 x + 10

then subtract 10 x from both sides and we get: -10 = 10 which is an absurd, therefore this equation has NO SOLUTION.

C)  6 x + 2 x - 8 = 8 (x - 1)

Combining like terms and using distributive property, we get:

8 x - 8 = 8 x - 8

which is an identity, So this is true for all possible x values, then the are INFINITE NUMBER OF SOLUTIONS

D) 2 x + 50 = 90

solving for x gives:

2 x = 40

x = 40/2

x = 20

which is a unique (ONE) solution.

E) 2 (x - 4) = 2 x + 10 - 18

Using distributive property and combining like terms we get:

2 x - 8 = 2 x -8

This is an identity which will give true for all real x-values. Therefore it has INFINITE NUMBER OF SOLUTIONS.

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given that;

Consider the following statements about the effect of different values of a on the function,
