Answer:
Step-by-step explanation:
Suppose x+3 < 0. Subtract 3 from both sides of the inequality.
x < -3
So, x+3 is negative when x < -3. When x>5,
x+3 > 8, which is positive, so the absolute value function has no effect.
|x+3| > 8

On a coordinate plane, solid circles appear at the following points: (negative 3, 2), (negative 3, 3), (1, 4), (1, negative 4), (2, negative 4), (2, negative 2).
How many points need to be removed from this graph so that it will be a function?
1 point
2 points
3 points
4 points
Answer:
3 points
Step-by-step explanation:
A function is a relation that maps elements of a set for the inputs (the domain, usually denoted with the variable x) into elements of another set, the set of the outputs (the range, usually denoted with the variable y).
So the relation can be represented with points (x, y), which means that point x is being mapped into point y.
Such that the needed condition is that each element of the domain is mapped into only one element in the domain.
So for example, if for a relationship we have the points (a, b) and (a, c)
The point a is being mapped into two different outputs.
Now let's go to our problem, we have the points:
(-3, 2), (-3, 3), (1, 4), (1, -4), (2, -4), (2, -2)
If we have repeated inputs, we need to remove points until we have one of each.
We can see that the inputs -3, 1, and 2 are repeated one time.
Then we need to remove one of each, for example if we remove the second, fourth and sixth points, the set becomes:
(-3, 2), (1, 4), and (2, -4)
This is a function.
Then we need to remove 3 points.

C) 3 POINTS

There are 10 Pokémon cards on a table. Three are identical Pikachu cards, two are identical Charmander
cards, four are identical Mew cards, and 1 is a Gengar card. How many different ways can these cards be arranged?
Answer:
These cards can be arranged in 3,628,800 ways.
Step-by-step explanation:
Number of arrangements of n elements:
The number of possible arrangements of n elements is given by:
[tex]A_{n} = n![/tex]
How many different ways can these cards be arranged?
10 cards, so:
[tex]A_{10} = 10! = 3628800[/tex]
These cards can be arranged in 3,628,800 ways.

A company has to buy computers and printers. Each computer, x, costs $550 and each printer, y, costs $350. If the company spends $8,800 and buys a total of 20 machines, how many of each did it buy?
Enter a system of equations to represent the situation, then solve the system.
Answer:
The company bought 9 computers and 11 printers.
Step-by-step explanation:
Given that a company has to buy computers and printers, and each computer, x, costs $ 550 and each printer, y, costs $ 350, if the company spends $ 8,800 and buys a total of 20 machines, to determine how many of each did it buy the following calculation must be performed:
20 x 550 + 0 x 350 = 11,000
15 x 550 + 5 x 350 = 10,000
10 x 550 + 10 x 350 = 9,000
9 x 559 + 11 x 350 = 8,800
Thus, the company bought 9 computers and 11 printers.

Answer:
12+m =85
Step-by-step explanation:
.....
......
....
Answer:
12+m=85
Step-by-step explanation:
m+85= 12 In this m would be equal to-73. It has nothing related to the statement above.
12-m= 85 If a number would have to be subtracted from 12 then the answer would have to be with a negative sign. (-)
12m= 85 12m can be written as 12*m
12+m= 85 is the correct answer.

The sum of three whole numbers is 27. The mean of the three whole numbers is 9, and the greatest number is twice the least number.
What is the greatest number?
9514 1404 393
Answer:
12
Step-by-step explanation:
Let x be the smallest number, and y be the middle number. Then the largest number is 2x and the sum is ...
x + y + 2x = 27 ⇒ y = 27 -3x
The requirement that the middle number is y gives rise to the inequality ...
x < y < 2x
Substituting for y, we have ...
x < 27 -3x < 2x
Adding 3x gives us ...
4x < 27 < 5x
These two inequalities give us the requirement that ...
27/5 < x < 27/4
5.4 < x < 6.75
The only whole number in that range is x = 6. So, the greatest number is 2×6 = 12.
The greatest number is 12.

HAVE A WONDERFUL DAY!!! please take care of yourself you deserve it :D
Step-by-step explanation:
HOPEFULLY THIS HELPS HERE: please read this so you can understand the problem too!!
so basically, first you are gonna find the triangle's perimeter. (reminder perimeter is add all sides) so 6+8= 14. then you are going to find the circumfrence of that circle using the formula 2πr and then divide by two since its HALF a circle. the radius is 5 (radius is half the diameter which would be 10) then put in your calculator 2π(5) and you should get 31.42. dont forget to divide by two since its half a circle. 31.42/2 =15.71. then add up your other lengths to that 14+15.71= 29.71(YOUR ANSWER :D)

Answer:
1. 16cm
2. 26dm
3. 20mm
4. 30dm
5. 78cm
Step-by-step explanation:
1. Perimeter of the square = 4cm + 4cm + 4cm + 4cm = 16cm
2. Perimeter = 8dm + 8dm + 5dm + 5dm
= 26dm
3. Perimeter of rectangle = 3mm + 3mm + 7mm + 7mm = 20mm
4. Perimeter of triangle = 8dm + 12dm + 10dm = 30dm
5. Perimeter = 23cm + 23cm + 16cm + 16cm = 78cm
Hope it is helpful...The cost to print Alice’s 4 by 5-inch photo is $0.45. Assuming that the cost per square inch of photo is constant, how much should it cost to print the enlarged photo? Explain how you found your answer.
Answer:
0.0225 for every inch increased in size for the printing the the photo
Step-by-step explanation:
*I'll start off by using this section to show my work...*
4 x 5 = 20 [tex]in^{2}[/tex] meaning that for every number multiplied with another, the total area of inches will be "Χ".
20 inches = [$]0.45
Meaning, for every 20 inches, 0.45 will duplicate... For example, 40 (Which is 20 + 20..) will be .45 + .45 = 0.9 (0.90), but half of 0.45 will be 0.225 making the area of inches 10.
0.45/20 = 0.0225 per inch squared.
Therefore, the answer for the cost to print the enlarged photo will be 0.0225 per inch upped.
Maureen went on a 3 day, 50 mile biking trip. The first day she biked 6 miles. The second day she
biked 19 miles. How many miles did she bike on the 3rd day?
Step-by-step explanation:
Given
d1 = 6 miles
d2 = 19 miles
d3 = ?
d1+d2+d3 = 50
6+19+d3 = 50
25+d3 = 50
d3 = 50 - 25
= 25miles

[tex]\angle CAB = 75[/tex]
The attached triangle
Required
Find [tex]\angle ABC[/tex]
First, calculate [tex]\angle BCA[/tex]
[tex]\angle BCA + 135 = 180[/tex] --- angle on a straight line
[tex]\angle BCA = 180 - 135[/tex]
[tex]\angle BCA = 45[/tex]
[tex]\angle ABC[/tex] is then calculated using:
[tex]\angle ABC + \angle BCA + \angle CAB =180[/tex] -- angle in a triangle
[tex]\angle ABC + 45+ 75=180[/tex]
[tex]\angle ABC =- 45- 75+180[/tex]
[tex]\angle ABC =60[/tex]

Answer:
a. Given, Give, Given, AAS
Step-by-step explanation:
AAS makes the most sense because you are only given information about 2 angles and a side, in that order
also the other answers don't work because vertical, alternate interior, and alternate exterior angles are only used as reasons when the angles are on parallel lines cut by a transversal, which is not the case here.
According to a study, 77 % of K-12 schools or districts in a country use digital content such as ebooks, audio books, and digital textbooks. Of these 77 %, 7 out of 20 use digital content as part of their curriculum. Find the probability that a randomly selected school or district uses digital content and uses it as part of their curriculum.
Answer:
26.95%
Step-by-step explanation:
The computation of the probability that randomly selected is shown below:
Since 77% school or district use digital content
And, of these 77%, 7 out of 20 use the digital content as the curriculum part
So based on the above information
The probability is
= 77% × 7 ÷ 20
= 26.95%
Hence, the probability is 26.95%
If the graph of the function f (X) is represented in the attached figure, which of the graphs presented in the options represents the graph of its inverse function?
Answer:
A. g(x) = 1/3x + 1Step-by-step explanation:
The line has points:
(0, -3) and (1, 0)It has y-intercept b = -3 and a slope:
m = (0 + 3)/1 = 3The equation:
f(x) = 3x - 3It inverse is (let's call it g(x)):
x = 3y - 33y = x + 3y = 1/3x + 1g(x) = 1/3x + 1The slope of the inverse function is 1/3 and the y-intercept is 1
The graph reflecting this is A

Step-by-step explanation:
Given that,
The radius of sphere, r = 6 cm
We need to find the volume of the sphere.
The formula for the volume of a sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3\\\\=\dfrac{4}{3}\times \pi \times (6)^3\\\\=904.77\ cm^3[/tex]
So, the volume of the sphere is equal to [tex]904.77\ cm^3[/tex].
