Answer:

its b

Step-by-step explanation:

i took the test.

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.

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:

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:

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°.
