Answer:

All Real x (x not = 9).

Step-by-step explanation:

When x = 9,  f(x) =  9/0 which is undefined.

So the Domain is All Real x, x not = 9.

Note: I am assuming your second equation is:

x = 2y - 1

Answer:

The solution to the system of equations is:

Step-by-step explanation:

Given the system of equations

2x+y=3

x = 2y - 1

solving the system of equations using the elimination method

[tex]\begin{bmatrix}2x+y=3\\ x=2y-1\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}2x+y=3\\ x-2y=-1\end{bmatrix}[/tex]

Multiply x-2y=-1 by2:     2x-4y=-2

[tex]\begin{bmatrix}2x+y=3\\ 2x-4y=-2\end{bmatrix}[/tex]

subtracting the equations

[tex]2x-4y=-2[/tex]

[tex]-[/tex]

[tex]\underline{2x+y=3}[/tex]

[tex]-5y=-5[/tex]

now solve -5y = -5 for y

[tex]-5y=-5[/tex]

Divide both sides by -5

[tex]\frac{-5y}{-5}=\frac{-5}{-5}[/tex]

Simplify

[tex]y=1[/tex]

For 2x+y=3 plug in y=1

[tex]2x+1=3[/tex]

subtract 1 from both sides

[tex]2x+1-1=3-1[/tex]

Simplify

[tex]2x=2[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{2}{2}[/tex]

Simplify

[tex]x=1[/tex]

Therefore, the solution to the system of equations is:

Step-by-step explanation:

1.)20x + 100 = 1440

-Let the number of couples be x. So, the total amount paid by all the couple’s are $20x. School paid $100 as security, so the total amount paid is

$ (20x + 100)

2.) 20x = 1440 - 100 ⇒ 20x = 1040

X = 52

3. ) The security money  is $100, so the couples paid $1440- 100 = $1040 in total. As the couples paid $ 20 each than- [tex]\frac{1040}{20}[/tex] = 52

Step-by-step explanation:

because quadratic equation means x^2+ or -ax+ or-b

Step-by-step explanation:

step 1. A = P(1 + r/n)^nt. this is the compounding equation where n is the number of compounds in a time t and P is the original amount. r is the rate.

step 2. A = 3000(1 + .04/365)^(365(1))

step 3. A = 3122.43. this is the total amount owed on the credit card which includes principle and interest. the interest is less 5he principle

step 4. 3122.43 - 3000 = 122.43

As per midsegment theorem of a trapezoid,

Segment joining the midpoints of the legs of the of the trapezoid is parallel to the bases and measure half of their sum.

Length of midsegment = [tex]\frac{1}{2}(b_1+b_2)[/tex]

3). MN = [tex]\frac{1}{2}(18+10)[/tex]

           = 14

4). MN = [tex]\frac{1}{2}(57+76)[/tex]

5). MN = [tex]\frac{1}{2}(AB+DC)[/tex]

    7 = [tex]\frac{1}{2}(AB+10)[/tex]

    14 = AB + 10

    AB = 14 - 10

Step-by-step explanation:

give them brain, they're correct.

The Unit Rate for Amy will be 22 pages per hour.

The Unit Rate is defined as means a rate for one of something.

We have,

Amy can read 88 pages in 4 hours.

So,

Now,

Number of pages Amy can read in 1 hour [tex]=\frac{88}{4}[/tex]

So,

Number of pages Amy can read in 1 hour = 22,

That means,

The  Unit Rate for Amy is 22 pages per hour.

Hence, we can say that the Unit Rate for Amy will be 22 pages per hour.

Step-by-step explanation:

Statement best describes the function, The function is increasing when x > 0.

We have given that,

A. The function is always increasing.

B. The function is never increasing.

C. The function is increasing when x > 0.

D. The function is increasing when x < 0.

A function is increasing when the y-value increases as the x-value increases, like this It is easy to see that y=f(x) tends to go up as it goes along.

We have to determine the statement best describes the function.

b)               Interrater reliability

c)               Internal consistency reliability

Step-by-step explanation:

Types of Reliability Tests:  

Test-retest reliability = measures the results consistency with the application of the same test at different times.

Interrater reliability = shows consistent ratings by different examiners.

Parallel forms reliability = uses alternative versions of an equivalent test to probe for similar results.

Internal consistency reliability = this test checks the consistency of individual items of a test.

3. is Not a function

4. Is a function

5. Is a function

Answer:

D

Step-by-step explanation:

No the function is not an exponential function as the domain values are not at regular intervals although the range values have a common factor.

The exponential function is a function which is formed by the unit e which is equal to 2.718.

The differences between x-values are  -1, -1, -1, -2 . . . . not a constant difference

The ratios of y-values are 2/8 = 0.5/2 = 0.125/0.5 = 0.25 . . . . a constant difference

The domain values do not have a common difference shows the common factor of the range values which are of no use. So, the function is not exponential.

Hence the table does not show exponential function in any way because the domain values are at regular intervals and the range values have a common factor 0.25.

Answer:

Step-by-step explanation:

This is a dotted line so we can automatically eliminate, b, e, g, h,  and j. The shading in greater than, so we can eliminate a, and d.

Now all we have left are c, f and *i,

*(because if converted to y intercept the sign will flip because the y is negative in this equation.)

Now convert to y intercept form (y=mx+b).

Flip the sign because some are negative.

C. y>(-5/2)x+0

F. y>-2x+9

I. y>(4/3)x-(5/3)

Now use rise over run, or you could just look at the b. B is equal to the y-intercept. It can't be 0 or 9, and (-5/3) is equal to -1.67. So isn't that the closest to what the y intercept looks like in the graph?
