Can someone pls explain to me how Identify the domain and range of a graph!!,
Answers
Answer:
Ok
Step-by-step explanation:
So, the domain is the set of all possible values that can be inputted into the function. Or where is function on the x axis is the function defined. The range is similar but on the y axis. In this case, the function you have there appears to go on to infinity (I assume that is what the arrow means) and so the range would be [-1, -infinity) and domain [1, infinity). Brackets are important here because it shows that the function is still defined at point (1,-1), therefore, I used [ bracket symbol (I again assumed that the shaded in black dot at point (1,-1) means that the function is closed at that point and that when it is not shaded in, it is open). I feel like I didn't explain very well but good luck and hopefully someone does a better job that what I did.

For the value of x = - 1, the correct equation is,
⇒ - 3x + 15 = 18
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The value of x is,
⇒ x = - 1
Now, Substitute the value of x in all equations and check the correct equation.
For equation 3;
⇒ - 3x + 15 = 18
Substitute x = - 1 ;
⇒ -3×-1 + 15 = 18
⇒ 3 + 15 = 18
⇒ 18 = 18
Thus, The correct equation is,
⇒ - 3x + 15 = 18

Answers
Answer:
they are the same thing
Step-by-step explanation:
Answer:
They are practically the same thing but if you want to get technical then they are related because A slope a measure of steepness. A line with a large slope, such as 25, is very steep. A line with a small slope, such as 1 /10 is very flat. So this means it will rise over run if that makes sense.

1) 5x- 5 = 4x + 13 ________
2)X- 5 = 13 ________
3) x= 18________
Options for each answer:
•Addition Property of Equality
•Distributive Property
•Multiplication Property of Equality
•Subtraction Property of Equality
•Transitive Property of Equality
Answers
Answer:
1. Distributive Property
2. Subtraction Property of Equality
3. Addition Property of Equality
The property that justifies each step of 5(x-1) = 4x + 13 is 5x - 5 = 4x + 13.
What is distributive property ?Distributive property is when we distribute and multiply in between addition and subtraction
Given 5(x-1) = 4x + 3.
We know a(b+c) = ab + ac which is distributive property.
So, 5(x-1) = 4x + 3.
5x - 5 = 4x + 3.
Solving these problem and finding the value of x
5x - 5 = 4x + 13.
5x - 4x = 13 + 5.
x = 18.

Rita just bought a car for 15,000. She paid 20% down and borrowed the remainder at an annual interest rate of 9.0%. The loan will be repaid over four years with monthly payments of $298.62. How much is rita's down payment and how much did she borrow?
Answers
Answer:
Rita's down payment is $3000 and she borrowed $12000.
Step-by-step explanation:
The cost of the car is $15000.
Given that she paid 20% down and borrowed the remainder.
So, Rita's down payment= 20% of $15000
[tex]=\frac{20}{100}\times 15000[/tex]
= $3000
As she borrowed the remainder cost, so,
the borrowed amount = 15000-3000
= $12000
Hence, Rita's down payment is $3000 and she borrowed $12000.
