for each of the number lines, write an absolute value equation in the form |x-c|=d, where c and d are some numbers, to satisfy the given solution set.
Answers
An absolute value is the numerical value of a number without consideration of its sign. It can be represented graphically by a straight line known as a number line. Absolute value equations are equations that include absolute values of variables or unknown quantities. The following are examples of how to write an absolute value equation in the form |x-c|=d to fit the provided solution sets:
Example 1:
Solution set: {x|x≤-3 or x≥1}
Absolute value equation: |x-(-1)|=4
Explanation: -1 is the midpoint of the two ranges (-3 and 1) in the solution set. |x-(-1)|=|x+1| is the absolute value expression for the midpoint -1. The distance d from -1 to the solutions' furthest endpoints, 1 and -3, is four, hence the value of d in the absolute value equation is 4.

At which root does the graph of f(x) = (x + 4)(x + 735 cross the x-axis?
Answers
9514 1404 393
Answer:
both of them: x = -4, x = -735
Step-by-step explanation:
The meaning of "real root" is that the graph intersects the x-axis at that value of x. If the degree of the root is odd, the graph crosses there. (If the degree of the root is even, the graph only touches the x-axis.)
f(x) = (x +4)(x +735)
has real roots at x = -4 and x = -735, so crosses the x-axis in those places.

One of the legs of a right triangle measures 12 cm and its hypotenuse measures 14Find the measure of the other leg. If necessary, round to the nearest tenth.
Answers
To obtain the measure of the other leg of the right triangle, the following steps are necessary:
Step 1: Draw a sketch of the right triangle and label it with the dimensions provided in the question, as below:
Step 2: Apply the Pythagorean theorem to obtain the measure of the other leg of the right triangle, as follows:
The Pythagorean theorem goes as follows:
\(\text{hypothenus}^2=\text{opposite}^2+\text{adjacent}^2\)Thus:
\(\begin{gathered} 14^2=12^2+x^2 \\ 196=144+x^2 \\ 196-144=x^2 \\ 52=x^2 \\ x^2=52 \\ x=\sqrt[]{52}=7.21 \\ x=7.2\text{ (to the nearest tenth)} \end{gathered}\)Therefore, the measure of the other leg of the right triangle is 7.2cm

Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
equation of blue line is y = x + 2 , in slope- intercept form
with slope m = 1
equation of red line is y = x - 3 , in slope- intercept form
with slope m = 1
• Parallel lines have equal slopes
then the blue and red lines are parallel.
the solution to the system is at the point of intersection of the 2 lines
since the lines are parallel then they do not intersect each other.
thus the system shown has no solution.
Ben's Barbershop has a rectangular logo for their business that measures 7(1)/(5) feet long with an area that is exactly the maximum area allowed by the building owner. Create an equation that could be used to determine M, the unknown side length of the logo.
Answers
An equation that could be used to determine M, the unknown side length of the logo is X = (36/5) x M
Let's assume that the unknown side length of the logo is 'M'. The logo is a rectangle, and the area of a rectangle is given by multiplying its length and width. Since we know the length of the logo is 7(1)/(5) feet, we can write the equation:
A = L x W
where A is the area of the logo, L is the length of the logo, and W is the width of the logo.
Substituting the given values, we get:
A = (7(1)/(5)) x M
or
A = (36/5) x M
Now, we know that the area of the logo is exactly the maximum area allowed by the building owner. Let's assume this maximum area is 'X'. So, we can write another equation:
A = X
Combining both equations, we get:
X = (36/5) x M
This is the required equation that could be used to determine the unknown side length 'M' of the logo if we know the maximum area allowed by the building owner 'X'.

Answers
As an operations manager for a plant that manufactures batteries, I can use both descriptive statistics and inferential statistics to make better managerial decisions
Descriptive statistics help me to summarize and describe the data collected from the manufacturing process.
For instance, I can use measures such as mean, median, mode, range, and standard deviation to summarize the data on the production output of batteries over a specific period.
Inferential statistics allow me to draw conclusions and make predictions based on the data collected from a sample of batteries produced.
For example, I can use inferential statistics to determine the probability of the battery meeting the required specifications. I can also use inferential statistics to make predictions about future production output, based on the historical data.

Use the graph of f(x) to find the solutions to the equation f(x)=0.
Answers
Answer:
x = -4, 7
Step-by-step explanation:
Pre-SolvingWe are given the graph of the function f(x), and we want to find the values that make the statement f(x) = 0.
f(x) = 0 means that there are certain values that make the value of f(x) (which can be considered as y) equal to 0.
SolvingWe can look to the graph to help us - we should look at where y is equal to 0, which is the x-axis.
On the x-axis, we can see that the function passes through both -4 and 7 (the graph goes up by 1) on that line.
As coordinate points, they are written as (-4,0) and (7,0).This means that when either -4 or 7 are substituted into the function (i.e. when they are equal to x), they will make the function equal 0.
So, it means that x = -4, 7.

Madison bought 58 invitations for $87. If each invitation is the same price,
how much would it cost her to buy 70 invitations?
Show your work.
Answers
Answer:
We can use proportion to solve this problem.
Let x be the cost of one invitation.
We can set up a proportion:
58/x = 87/1
To solve for x, we can cross-multiply:
58 * 1 = 87 * x
58 = 87x
x = 58/87
x = 0.67
So one invitation costs $0.67.
To find the cost of 70 invitations, we can multiply the cost of one invitation by 70:
70 * $0.67 = $46.90
Therefore, it would cost Madison $46.90 to buy 70 invitations.

Area of the rectangle
Area of a rectangle is the sum of the area of two equal right triangle.
Area of rectangle = 2(area of right triangle)
Area of rectangle = 2(44 sq inches) = 88 sq inches
Total area of the triangle with respect to length and width of the rectangleLet the length = x

21.6 Computer use. A random sample of 197 12th-grade students from across the United States was surveyed, and it was observed that these students spent an average of 23.5 hours on the computer per week, with a standard deviation of 8.7 hours. If we plan to use these data to construct a 99% confident interval, the margin of error will be approximately (a) 0.07. (b) 0.62. (c) 1.6. (d) 8.7.
Answers
Answer:
(c) 1.6
Step-by-step explanation:
Calculation for what the margin of error will be approximately
First step is to calculate Total hours spent
Total hours spent = (197 * 23.5 hours)
Total hours spent =4,625 hours
Second step is to find the square root of the sample size
Sample size=√197
Sample size=14.04
Third step is to divide the Standard deviation of 8.7 hours by square root of sample size of 14.04
= 8.7 hours /14.04
= 0.6196
Fourth step is to use the Z table to find Z value at 99% confidence
Z value at 99% confidence = 2.58
Last step is to calculate the Margin of error
Margin of error = 0.6196 * 2.58
Margin of error = 1.59857
Margin of error= 1.6 (Approximately)
Therefore what the margin of error will be approximately is 1.6

Problem 13, part A
Recall that the term "circumference" is a special name for the distance or perimeter around a circle. Think "circle fence" which sounds a bit like "circumference", at least if you say it fast enough. That's how I remember it.
We're given 100 feet of fencing and we need to find the diameter of the circle that can be formed with this amount of fencing. We'll plug C = 100 into the circumference formula below and solve for d.
C = pi*d
100 = 3.14d
3.14d = 100
d = 100/(3.14)
d = 31.84713
The diameter of this circle is roughly 31.84713 feet
=========================================================
Problem 13, part B
Cut the diameter we just found in half to get
r = d/2
r = (31.84713)/2
r = 15.923565
Now use this radius value to find the area of this circle
A = pi*r^2
A = 3.14*(15.923565)^2
A = 796.178156
The area of the circle is roughly 796.178156 square feet
