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:

( − ∞ , ∞ )

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.

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°.

Answer:

I think its the second one but I might not be right.

Step-by-step explanation:

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

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.

Answer:

Step-by-step explanation:

If D is rotated 90 degrees clockwise then it should wind up at (0,2). Try drawing the quadrilateral to see why this is true.

E' would be (0,3)

C' would be (5,1)

F' would be (-3,-3)

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.

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.

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.
