Answer:
The answer would be D
Step-by-step explanation:
The inequality x>1.5, or x is greater than 1.5, has to have a line going to the right because x has to be greater than 1.5, so answers B and C can't be it. Because the symbol is greater than instead of greater than or equal to, the circle will be open, and the circle for option A is closed, so the answer is D

Yes 6 is the solution of the equation because replacing x with 6 and simplifying on the left side results in - 2, which equals the right side.
What is the basic equation?When two expressions are connected with the equals sign (=) in a mathematical formula, it expresses the equality of the two expressions. An equation is an algebraic statement that demonstrates two mathematical expressions are equivalent in algebra, and this is how it is most usually used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal." When two expressions are joined by an equal sign, a mathematical statement is called an equation.
The given equation is x - 9 = - 3.
The given solution to the equation is 6.
Put 6 in place of x in the equation
6 - 9 = - 3
- 3 = - 3
So, the left-hand side of the equation is equal to the right-hand side. So, 6 is the solution to the equation x - 9 = - 3..

Rigid Transformations:Question 1Circle P has center (-9, 3) and radius 3. Circle P' is formedby shifting circle P to the right 4 units and reflecting aboutthe line y = x. What is the coordinate of the center of circleP'?Select one:O(-13, 3)O(-5,3)O(3.-13)(3-5)
Answers
To shift the coordinates in a cartesian plane we have to remember that a translation can be described as:
[tex](x,y)\rightarrow(x+a,y+b)[/tex]where a and b is the amount we would like to translate in the horizontal and vertical direction, respectively.
In this case we would like to translate the center to the right four units, then a=4. Since we don't wish to translate it in the vertical direction then b=0. Then, the center, after the tanslation is
[tex]P^{}=(-9+4,3)=(-5,3)[/tex]Now, if we want to reflect about the line y=x we have to remember that the rule describing it is
[tex](x,y)\rightarrow(y,x)[/tex]Then the point P' is
[tex]P^{\prime}=(3,-5)[/tex]Therefore the center of the circle after the transformations given is (3,-5)

Answer:
x = 7/9
Step-by-step explanation:
Given equation,
→ 3x - 5 = 2 - 6x
Now the value of x will be,
→ 3x - 5 = 2 - 6x
→ 3x + 6x = 2 + 5
→ 9x = 7
→ [ x = 7/9 ]
Hence, value of x is 7/9.
A school sells adult tickets and student tickets for a play. It collects $1,400 in total The graph shows the possible combinations of the number of adult tickets sold and the number of student tickets sold. What does the vertical intercept (0.200) tell us in this situation? O (1 Point) It tells us the decrease in the sale of adult tickets for each student ticket sold It tells us that if no adult tickets were sold, then 200 student tickets were sold It tells us that is no students tickets were sold, then 200 adult tickets were sold It tells us the decrease in the sale of student tickets for each adult ticket sold.
Answers
In the graph, the horizontal axis represents the number of adult tickets sold
And the vertical axis represents the corresponding number of student tickets sold.
The vertical intercept, as we are indicated is at (0,200)
That point is at 0 in the horizontal axis and at 200 on the vertical axis, comparing with what each axis represents:
(0,200) represents that when 0 adult tickets are sold, 200 student tickets are sold.
Answer:
it tells us that if no adult tickets were sold, 200 student tickets were sold
