Simplify completely
x2 + 4x - 45
and find the restrictions on the variable.
Answer:
(x-5)/(x+1) and x cannot equal -1 because the denominator can't be zero.
Step-by-step explanation:
Factor the numerator:
(x+9)(x-5)
Factor the denominator:
(x+1)(x+9)
So you have
(x+9)(x-5)/(x+1)(x+9); see that you can cross out the (x+9) in both the numerator and denominator?
You're left with (x-5)/(x+1)
The only number that is restricted is -1, because that would make the denominator zero, which is a no no!!

In 2003, the population of an African country was about 9.9 million people, which is 3 million more than 3
times the population in 1950.
Enter and solve an equation to find the approximate population p (in millions) in 1950.
An equation is 9.9+3
=p
The approximate population in 1950 was 12.9
million people.

A company makes a profit of $60 per software program and $45 per video game. The company must produce both and can produce at most 225 software programs and at most 350 video games per week. Total production cannot exceed 455 items per week.
(a) Write out the set of inequalities you would use to represent the constraints in this situation.
(b) Identify the corner points.
(c) How many items of each kind should be produced per week to maximize profit? Show your work. Be sure
to show the comparison in your work.
Use linear programming to solve.
Step-by-step explanation:
a)
(a)255+350 <455
ans...605-455
..150
.........profit per week is 60 +45
105.
105 x 150
weekly profit is..$15750
Answer:
See below.
Step-by-step explanation:
Let's first define our variables. Let's let:
x denote the amount of software programs made and
y denote the amount of video games made.
Part A)
Now, let's write our equations and constraints.
The company can produce at most 225 software programs. So:
[tex]x\leq225[/tex]
And the company can produce at most 350 video games. So:
[tex]y\leq 350[/tex]
Total product (the sum of software programs and video games) cannot exceed 455 items per week. In other words:
[tex]x+y\leq455[/tex]
Part B)
Refer to the first graph:
We have four corner points: A, B, C, and D.
The darkest portion represents the feasible portion. Any combination of software programs and video games within this portion can be produced.
Part C)
Refer to the second graph.
To find what to produce to find the maximum profit, let's write an equation. Let P equal to maximum profit. So, it would be the sum of the total profit from the software programs and video games. We can write the following equation:
[tex]P=60x+45y[/tex]
Let's solve for y in order to graph it. Subtract 60x from both sides:
[tex]45y=-60x+P[/tex]
Divide both sides by 45:
[tex]y=-\frac{4}{3}x+\frac{P}{45}[/tex]
In order produce the maximum profit, P must be the greatest while simultaneously touching our corner points.
Note: The P, Q, R, and S are just rough estimates.
I've graphed four versions of our equation using different variables (for P). We can see that the equation with the highest profit P is the one the crosses point C with P equaling approximately $24,000.
Therefore, in order to maximize profits, the company should produce (Remember that C is at (225, 230)) 225 software programs and 230 video games.
And we're done!

what is the midpoint of BD
Answer:
I don't know what your numbers are, but if it is on a number line, just add the absolute values (always positive) of the endpoints together, and divide by 2 (find the average).
On a graph, find the average of the x coordinates, (that is midpoint x value) and the average of the y coordinates (that is midpoint y value)
Step-by-step explanation:
If you have a negative number, the absolute value is the same number, just positive. E.X. -4 the absolute value is 4.
Anita found a 16-ounce jar of pickles that costs $4.80. She wants to buy the 24-ounce jar, but the price is not listed. If the unit price is the same for both sizes, how much does the 24-ounce jar of pickles cost?
Answer:
$7.20
Step-by-step explanation:
16/4.80 = 24/?
Answer:
7.20
Step-by-step explanation:
First find what one oz. costs. To do this, divide 4.80 from 16. This is 3 rounded. Multiply 3 by 24. This is 72. Move the decimal to the left once, to get 7.20.
3. A solid sphere of radius 3 cm is melted and then recast into small spherical balls, each of
diameter 0.6 cm. Find the number of small balls so obtained.
Answer:

Biff scored a 65. What is Biff's percentile?
Answer: 10th Percentile
Step-by-step explanation:
The percentile of a variable in a dataset is the percentage position of the variable in the dataset such that the variables before this variable are below this percentage.
There are 20 variables in this data set and Biff scored a 65 which occupies the second and third positions on this dataset.
Picking the first position, 65 is the second variable in the data set so Biff's percentile is;
= Position on dataset/ No. of variables in data set
= 2/20
= 10%
= 10th percentile
name the property of equality that the statement illustrates
If x = y, then y = x.
Answer: Symmetric Property
Explanation: The symmetric property states that x = y, then y = x.
So the symmetric property allows us to
switch the left and right sides of an equation.

Which transformation produces another triangle that has the same area as the one shown?
Answer:
A
Step-by-step explanation:
A reflection in the line y = -2 and then translation of 2 units right will create the same area so option (C) will be correct.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
If we shift the triangle anywhere then there will be no change in the area but if we apply the scale factor then since the dimension changes so its area will also change.
In all options, there is a scale factor so it will change area but in option C
A reflection in the line y = -2 reflection gives a mirror image about y = -2 but no changes in area then translation of 2 units right will shift triangle 2 units right but no effect in the area.
Hence "A reflection in the line y = -2 and then translation of 2 units right will create the same area".

The solution to the given equation r+15=4r-6 is 7.
The equation is r+15=4r-6.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, r+15=4r-6
Transpose -6 to the other side of the equation, we get
r+15+6=4r
r+21=4r
Transpose r to the other side of the equation, we get
