Answer: 113.04

Let's begin by identifying key information given to us:

x is lesser than or equal to plus or minus 2

We will proceed to plot the graph

The numbers whose difference are calculated could be 300 and 41

From the question, we have the following statement that can be used in our computation:

The difference between two numbers is 259

Represent the two numbers with x and y

So, we have the following representation

x - y = 259

Make x the subject of the formula

This gives

x = 259 + y

Assume y is 41

So, we have

x = 259 + 41

Evaluate the sum

x = 300

Hence, the numbers are 300 and 41

The slope-intercept form of the given equation is y = 8x - 9

What is slope intercept form?

Using a straight line's slope and the location of its y-axis intersection, the slope-intercept equation can be used to determine the general equation of the line. Y = mx + b is the equation in slope-intercept form.

The slope-intercept form is y=mx+b, where

m is the slope and

b is the y-intercept.

Here, we have

Given equation = -8x + y = -9

Rewrite in slope-intercept form.

Add 8x on both sides of the equation and we get

y = -9 + 8x

y = 8x - 9

Hence, the slope-intercept form of the given equation is y = 8x - 9

Yello paint: 1 1/5

Green paint: 1 1/6

Blue paint: 7/8

After using 3/4 of each paint color, we have

- Yellow:

The least common multiple of 5 and 4 is 20, then...

So, for yellow paint, we will have 9/20 gallons

- Green:

The LCM of 6 and 4 is 12

So, for green paint, we will have 5/12 gallons

- Blue:

LCM of 4 and 8 is 8

So, for blue paint, we will have 1/8 gallons

Now, we add them upp in order to obtain our anwser:

The LCM of 8, 12 and 20 is 120

In conclusion, he will have left 119/120 gallons of paint

To solve for x in any specific equation, we need to isolate x in one side of the equation. we can do that by adding, subtracting, multiplying, or dividing by a specific number on both sides of the equation.

For example:

X + 3 = 7

X + 3 - 3 = 7 - 3

X = 4

We solve for x when we subtract 3 on both sides of the equation.

1) Since the degree of the denominator is lower than the numerator's we can divide these expressions through long division that way:

As we can see in each step the aim is to cancel the leading coefficient.

2) Note that a Long Division, has a way to write its answer so we can tell that this is the answer:

Note that the remainder is written above the divisor on the final answer.

Okay, here we have this:

Considering the provided figure and information, we are going to calculate the requested measure, so we obtain the following:

So to calculate the length of the base, we will solve in the formula for the area of the triangle, we have:

Triangle Area=(Base*height)/2

Triangle Area*2=Base*height

Base=(Triangle Area*2)/height

Let's replace:

Finally we obtain that the length of the base of triangle is 9 cm.

You have the following information:

- Two-thirds (which means 2/3) of the people on a hike are adults.

- There are 36 adults

In order to calculate the number of people, you consider that 36 is 2/3 of the total people. If you name x as the total people, the number of adults is 2/3x. Thus, you can write the following algebriac expression:

2/3 x = 36

you solve the previoues equation for x. First, you multiply both sides by 3 and you divide both sides by 2.

x = 36(3/2) = 108/2 = 54

Hence, the number of people on the hike is 54

SOLUTION

The principle behind the Exterior Angle Theorem is that:

the sum of two interior angles is equal to one exterior angle.

In this question, we have that :

X + ( X - 48 ) = X + 50

Collecting like terms, we have that:

2 X - 48 = X + 50

2X - X = 50 + 48

X = 98 Degrees.

CONCLUSION: The value of X = 98 Degrees.

Distributive Property

The distributive property of the product with respect to the sum states that if a product and a sum are to be operated like follows:

x* ( y + z )

Then the result is the product of x by each term separately:

x* ( y + z ) = x*y + x*z

Now, we have the expression:

8 ( 2m + 1 )

Applying the distributive property:

8 * 2m + 8 * 1

Assuming there are 52 woking weeks in a year (Since it is the standard used by companies). And in week Jessica can have a maximum of 40 hours, we can conclude that;

Therefore Jessica's hourly rate is $18.51.

And by calculating her salary per year if she is paid hourly, let us again assume that there are 52 working weeks in a year and she works 8 hours per day 5 times a week as the standard working hours. We get;

Therefore Jessica's salary per year if she is paid hourly is $38,500.80, so there is a $0.80 difference between her initial salary.

you could calculate the derivative and equalize it to zero,then you can evaluate the function in the boundary points of the domainand compare them to the ones found in the last step to find the maximum of a given function.
