Step-by-step explanation:
10 + 3x < 4 or 2x + 5 > 11 in interval notation
Answer:
( − ∞ , ∞ ) hope i help
Step-by-step explanation:
First, solve each inequality. I'll solve the first one first.
7 ≥ 2 x − 5
12 ≥ 2 x
6 ≥ x
Therefore, x could be any number less than or equal to 6. In interval notation, this looks like:
( − ∞ , 6 ]
The parenthesis means that the lower end is not a solution, but every number above it is. (In this case, the lower end is infinity, so a parenthesis must be used, since infinity is not a real number and so it cannot be a solution.) The bracket means that the upper end is a solution. In this case, it indicates that not only could
x
be any number less than 6, but it could also be 6.
Let's try the second example:
3 x − 2 4 > 4
3 x − 2 > 16 3 x > 18 x > 6
Therefore, x could be any number greater than 6, but x couldn't be 6, since that would make the two sides of the inequality equal. In interval notation, this looks like:
( 6 , ∞ )
The parentheses mean that neither end of this range is included in the solution set. In this case, it indicates that neither 6 nor infinity are solutions, but every number in between 6 and infinity is a solution (that is, every real number greater than 6 is a solution).
Now, the problem used the word "OR", meaning that either of these equations could be true. That means that either x is on the interval ( − ∞ , 6 ] or the interval ( 6 , ∞ )
. In other words, x
is either less than or equal to 6, or it is greater than 6. When you combine these two statements, it becomes clear that
x
could be any real number, since no matter what number
x
is, it will fall in one of these intervals. The interval "all real numbers" is written like this:
( − ∞ , ∞ )

Which answer explains whether the table of values represents a function? x y –4 –5 –2 2 0 3 1 –7 –6 –9 Yes, the values represent a function because each x-value is paired with only one y-value. Yes, the values represent a function because each y-value is paired with only one x-value. No, the values do not represent a function because the x-values are not in ascending order. No, the values do not represent a function because there is no single rule that relates each pair of values.
The answer is A,
In a function, an x value can only be paired with one y value.
However, a y value and have multiple different x values, for example when you graph a constant/horizontal line.
The given table represents a function as for every x, there is only one y.
This is best explained in the first option: Yes, the values represent a function because each x-value is paired with only one y-value.
What is a function?A function is a relation between a dependent and an independent variable, say y and x respectively, written as y = f(x). Any such relationship will be called a function if and only if, there is only one value of y corresponding to every x.
How to solve the question?In the question, we are asked about the values in the table:
x y
-4 -5
-2 2
0 3
1 -7
-6 -9,
whether these values represent a function or not.
We know that for a relationship to be a function, there should be only one value of the dependent variable (y) for every independent variable (x).
This is true for the given values as for every x value, we only have one y value.
Thus, we can say that the values represent a function because each x-value is paired with only one y-value. Hence, the first option is the right choice.

What is m∠PTR? a. 12 b. 40 c. 50 d. 140
Answer:
d. 140
Step-by-step explanation:
QTR is a 180 degree angle, so we can assume PTR is 140 degrees because (x+28) is (12+28)= 40
The required m∠PTR is 140°.
It is required to find the m∠PTR.
What is angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.
Given:
We have to find the value of x.
According to given question we have.
m<PTQ = (x + 28)°
m<RTS = (2x + 16)°
m<PTQ = m<RTS (vertical opposite angles are congruent)
Therefore:
x + 28 = 2x + 16
Solve for x. Combine like terms
28 - 16 = 2x - x
12 = x
x = 12
Find m<PTQ
m<PTQ = (x + 28)
plug in the value of x
m<PTQ = 12 + 28 = 40°
m<PTR + m<PTQ = 180° (supplementary angles)
m<PTR + 40° = 180° (substitution)
m<PTR = 180 - 40 (subtracting 40 from each side)
m<PTR = 140°
Therefore, the required m∠PTR is 140°.

(a) For what values of x will this expression be
equal to zero? Show how you arrived at your
Answer
Answer:
x-8 to get the zero for the 8 you have to add it. And for the second part you have to subtract four from itself.
Step-by-step explanation:
From the expression (x - 8) (x + 4), the values of x need to be 8 or -4, for x to be equal to zero.
Given that:
(x - 8) (x + 4) = 0
The expression from above is the expanded form of a given quadratic equation.
To find the quadratic equation, we will use the values of one enclosed bracket to multiply the values of the other.
i.e.
(x -8) (x + 4) = 0
x² + 4x - 8x - 32 = 0
x² - 4x - 32 = 0
(So, this above expression shows the quadratic equation from which the roots of (x-8) (x-4) is being derived from)From the roots;
(x - 8) (x + 4) = 0
Let;
(x - 8) = 0 or (x +4) = 0
x - 8 = 0 or x + 4 = 0
x = 8 or x = -4
Therefore, we can conclude that the value of x needs to be 8 or -4 for x to be equal to zero.
