A program can only create one object of each class.
A. True
B. False

Answers

Answer 1

Answer:

False.

Step-by-step explanation:

Answer 2

Answer:

False / It Depends

Step-by-step explanation:

The simplest way to create a class with one one instance is to use an enum. public enum Singleton { INSTANCE } You can compare this with Steve Taylor's answer to see how much simple it is than alternatives. BTW: I would only suggest you use stateless singletons. If you want stateful singletons you are better off using dependency injection. ( You can create more than one tho )

But, the singleton class means you can create only one object for the given class. You can create a singleton class by making its constructor as private, so that you can restrict the creation of the object. Provide a static method to get instance of the object, wherein you can handle the object creation inside the class only.

Hope this helps! <3

Jenna found three solution to a linear equation she graphed them, but they don't lie in a straight line. What errors could jenna have made? Explain.

Answers

Answer:

A system of linear equation could only have 1 solution. This is because the straight lines will only have to meet, cross, or intersect each other once.

A system of linear equation could only have 1 solution. This is because the straight lines will only have to meet, cross, or intersect each other once.

There are many different methods in arriving to the final answer. However, errors cannot be perfectly avoided. One of these errors to mistakenly identify equations as linear. It is important that we know that the equations we are dealing with are of exact or correct  characteristics.

Also, if she had used substitution method, she might have mistakenly taken the value of one variable for the other.

What is the slope of the line that passes through the points (-3, -3)(−3,−3) and (-18, -23) ?(−18,−23)? Write your answer in the simplest form.

Answers

Answer:

Let's see what to do buddy...

Step-by-step explanation:

_________________________________

Step (1)

To find the slope of linear functions using two points, we have the following equation :

[tex]slope = \frac{y(b) - y(a)}{ x(b) - x(a) } \\ [/tex]

Where a and b are two point of the function.

_________________________________

Step (2)

Well now I want to choose a name for the given points :

a = ( -3 , -3 ) b = ( -18 , -23 )

_________________________________

Step (3)

It's time to put the the coordinates in the above equation :

[tex]slope = \frac{ - 23 - ( - 3)}{ - 18 - ( - 3)} \\ [/tex]

[tex]slope = \frac{ - 23 + 3}{ - 18 + 3 } \\ [/tex]

[tex]slope = \frac{ - 20}{ - 15} \\ [/tex]

Negatives simplified :

[tex]slope = \frac{20}{15} \\ [/tex]

The face and denominator are reduced to five :

[tex]slope = \frac{4}{3} \\ [/tex]

_________________________________

And we're done.

Thanks for watching buddy good luck.

The temperature on Monday was 14 degree Celsius. On Tuesday the temperature decreased by 5 degree. On Wednesday, the temperature decreased another 10 degree. On Thursday the temperature increased by 8 degrees. What was the temperature at the end of the day on Thursday?

Answers

Answer:

7 degrees

Step-by-step explanation:

The temperature in Monday was 14 degrees

On tuesday the temperature decreased by 5 degrees

On Wednesday it decreased by 10 degrees

On thursday the temperature increased by 8 degrees

Therefore the temperature at the end of the day on Thursday can be calculated as follows

= 14 - 5 - 10 + 8

= 7

Hence the temperature at the end of the day on Thursday is 7 degrees

Answer:

x=9

Step-by-step explanation:

First, midpoint means “the middle” so that mean that segment AB is half of AC. You can make an equation: 5x+18=4.5+6.5x. After that, you have to move the numbers on one side and the variables on the other.

You then come up with 13.5=1.5x

Divide both of them by 1.5 and then you get x=9

Answer:

X=9

Step-by-step explanation:

Okay first Hello! :)

so, B is the mid point of the segment midpoint means the half way

so, if AB= 5x+18 is the half to get the whole you would need to times it by 2

you get 10x+36

so now you equal them together

10x+36= 13x +9

Always move your smaller x, and now you got

3x+9=36

move your 9 over and switch the sign you get

3x=27

divide by three and you get

X=9

[tex](2x - 9) + (3x - 6) = 110[/tex]

[tex]2x + 3x - 9 - 6 = 110[/tex]

[tex]5x - 15 = 110[/tex]

Plus sides 15

[tex]5x - 15 + 15 = 110 + 15[/tex]

[tex]5x = 125[/tex]

Divided sides by 5

[tex] \frac{5}{5}x = \frac{125}{5} \\ [/tex]

[tex]x = 25[/tex]

Thus ;

A = 2 ( 25 ) - 9°

A = 50° - 9°

A = 41°

_________________________________

B = 3 ( 25 ) - 6

B = 75° - 6°

B = 69°

_________________________________

C + 110° = 180°

because it is a straight line.

Subtract sides 110°

C + 110° - 110° = 180° - 110°

C = 70°
