First we can check the value 9 that is added inside the absolute module operator.
This value is together with the variable x inside the operator, that is, from f(x) we can replace x by 'x + 9' in order to get the first part of g(x)
This addition of 9 to the value of x represents a horizontal translation of 9 units to the left.
Then, the subtraction of 5 units outside the absolute module operator is a addition/subtraction to the function, that is, we can subtract 5 units from f(x) in order to get this second part of f(x).
This subtraction of 5 units to the value of f(x) represents a vertical translation of 5 units down.
So the answer is:
To get the function g(x), shift f down by 5 units and to the left by 9 units.

When you convert a number from decimal notation to scientific notation, how do you know if the exponent will be positive or negative? Explain.
When converting a number from decimal to scientific notation,
The exponent is positive if the movement of the decimal point is to the left
The exponent is negative if the movement of the decimal point is to the right.
Examples :
[tex]1200\rightarrow1.2\times10^3[/tex]The decimal point moves from the right of the last digit to the place between 1 and 2. It moves to the left so the exponent is positive.
[tex]0.0012\rightarrow1.2\times10^{-3}[/tex]The decimal point will move 3 places to the right, so the exponent will be negative.

Fill in the blanks below.(a) Ivanna lost 40 dollars from her pocket.Write a signed number to represent this change.(b) A car corporation produced 540 more cars this month than last.Write a signed number to represent this month's change in production.
Recall that the signs
[tex]+,\text{ and -}[/tex]helps us indicate if there is an increase or a decrease.
If the number represents a decrease from the previous one, we put a minus sign. If the number represents an increase then we put a plus sign.
Notice that Ivanna lost $40, therefore, the total money she had decreased by 40.
If the company produced 540 more cars this month than last month, then there was an increase of 540 in cars production.

Before we can determine the absolute extrema of the function, let's graph the given function first. f(x) = x² - 6x.
For the interval [-1, 6], we can see that the maximum value would be at x = -1.
Let's replace x with -1 in the function above.
[tex]\begin{gathered} f(x)=x^2-6x \\ f(-1)=(-1)^2-6(-1) \\ f(-1)=1+6 \\ f(-1)=7 \end{gathered}[/tex]Therefore, the maximum between the interval [-1, 6] is at (-1, 7).
On the other hand, looking at the interval (3, 7] in the graph, the maximum is found at x = 7. To determine the maximum point, replace "x" with 7 in the function above.
[tex]\begin{gathered} f(7)=7^2-6(7) \\ f(7)=49-42 \\ f(7)=7 \end{gathered}[/tex]Therefore, the maximum at the interval (3, 7] is at point (7, 7).

The required perimeter of the scale drawing is given as 18 inches.
Given that,
The rectangular floor of a classroom is 30 feet in length and 24 feet in width. A scale drawing of the floor has a length of 5 inches. The perimeter, in inches, of the floor in the scale drawing, is to be determined.
Perimeter is the measure of the figure on its circumference.
Here,
According to the question,
L = 30 feet, W = 24 feet,
for Scaled drawing
l = 5 inch, w = x
Now,
30/5 = 24 / x
6 = 24 / x
x = 24 {1/6}
x = 4,
So the width of the scale drawing is 4 inches,
perimeter of the scaled drawing = 2[l + w]
= 2 [5 + 4] = 18 inches
Thus, the required perimeter of the scale drawing is given as 18 inches.

The picture that I sent to the app would not pick up the greater or less than signs. The instructions say solve the system of inequalities by graphing. I would like someone to walk me through the steps. I had an amazing tutor the last time but my connection got lost she sent me a graph to help me.
See graph below
Explanation:We have two inequalities:
y < 6
y > x + 3
To plot the inequalities on a graph, we change the inequality sign to equal to in order to get points to plot the graph:
y = 6
This means at y = 6, there will be an horizontal line for all values of x. But due to the less than sign, it means the horizontal line will be shaded down.
y = x + 3
We assign values to x inorder to get y values:
let x = -2, 0, 2, 4
when x = -2
y = -2 + 3 = 1
when x = 0
y = 0 + 3 = 3
when x = 2
y = 2 +3 = 5
when x = 4
y = 4 + 3 = 7
When we plot this points, we get a straight line. SInce the sign is greater than, the line will be shaded towards the positive side
plotting the graph:
First inequality
Both inequalities:
There are approximately 2.54 cm in 1 inch. what is the distance in inches of 14 cm. use a proportion to solve and round your answer to the nearest 10th of an inch
We know that there are 2.54 cm in 1 inch
2.54 cm ⇔ 1 inch
We want to find what is the distance in inches of 14 cm:
14 cm ⇔ ?? inch
Then, we have the following equivalence:
14 cm ⇔ ?? inches
2.54 cm ⇔ 1 inch
If we divide both sides of the equivalence we would have the same proportion:
[tex]\frac{14}{2.54}=\frac{?\text{?}}{1}[/tex]Solving both sides of the equation:
[tex]\begin{gathered} \frac{14}{2.54}=\frac{?\text{?}}{1} \\ \downarrow \\ 5.51=\text{??} \end{gathered}[/tex]This means that:
14 cm ⇔ 5.51 in
Rounding the answerWe want to round our result to the nearest tenth. This is a number with one digit after the decimal point:
5.51 in ≅ 5.5 in
Answer: the distance in inches of 14 cm is 5.5 inGeometry formulas Situation: Find the perimeter of a rectangular area with a length of 13 inches and a width of 7 inches. Calculation With Distribution (Show all steps.) Calculation Without Distribution (Show all steps.) I think is easier: to distribute. to not distribute. Why I think it is Easier
a rectangular area with a length of 13 inches and a width of 7 inches.
Length of rectangle = 13 inches
Width of rectangle = 7 inches
With Distribution:
The perimeter of any polygon is the sum of all the sides of the polygon
In the given rectangle we have 2 lengths and 2 widthSo,
Perimeter = length + width + Length+ width
Substitute the value and solve
Perimeter = 13 + 7 +13 +7
Perimeter = 20 + 20
Perimeter =40inches
Without Distribution
The perimeter of rectangle is express as :
Perimeter = 2(length + Width)
Substitute the value and solve
Perimeter=2(13+7)
Perimeter=2(20)
Perimeter-40 inches
It was easier without distribution because it becomes calculation easy.
Answer: Perimeter = 40 inches
It is easier to not distribute
Because it makes calculation easy and short.

Given relation is

Since distance and time both vary, therefore, they are not constants.

Here, we want to get the value of x
As we can see, we have the interior angle as 45;
The other is 90; and that means the last angle will be 45
This mean that we have an isosceles right-triangle
The sides that face the angles are equal
These sides are x and 12
That means x = 12
To get the value of y, we have to use the Pythagoras' theorem
The square of the hypotenuse (the longest side and the side that faces the right angle) is equal to the sum of the squares of the two other sides
The side facing the right angle is y
So, the sum of the squares of x and 12 will give the square of y
Mathematically, we have this as follows;
[tex]\begin{gathered} y^2=12^2+x^2 \\ \sin ce\text{ x = 12} \\ y^2=12^2+12^2 \\ y^2\text{ = 144 + 144} \\ y^2\text{ = 288} \\ y\text{ = }\sqrt[]{288} \\ y\text{ = 12}\sqrt[]{\text{ 2}} \end{gathered}[/tex]14. What property is used to show that 3(4-6) = 12-18?

Which order pair makes both inequalities true? Y<-2x+3Y< x-2
The ordered pair which makes both inequalities true are (3, 0).
Inequalities are mathematical expressions where neither side is equal.
Contrary to equations, we compare two values in inequality.
Less than, greater than, or not equal to signs are used in place of the equal to sign in between.
Let us consider the ordered pair (3, 0)
In the first inequality
y > -2x + 3
Substituting the values of x and y
0 > -2(3) + 3
0 > -6 + 3
0 > -3
In the second inequality
y < x - 2
Substituting the value of x and y
0 < 3 - 2
0 < 1
Therefore, the ordered pair which makes both inequalities true are (3, 0).
