Select all the relations that represent a function.

Answer:

y = (x - 3.5)^2 - 18.25

Step-by-step explanation:

y = x^2 – 7x - 6

y = (x^2 – 7x) - 6

y = (x^2 – 7x + 3.5^2 - 3.5^2) - 6

y = (x^2 – (2)(3.5)x + 3.5^2) - 3.5^2 - 6

y = (x - 3.5)^2 - 3.5^2 - 6

y = (x - 3.5)^2 - 18.25

Answer:

a) x = 1.52

b) s = 1.16

Step-by-step explanation:

We have that:

5 students watched 0 movies.

9 students watched 1 movie.

5 students watched 2 movies.

5 students watched 3 movies.

1 student watched 4 movies.

(a) Find the sample mean x.

Sum divided by the number of students. So

[tex]x = \frac{5*0 + 9*1 + 5*2 + 5*3 + 1*4}{5 + 9 + 5 + 5 + 1} = \frac{38}{25} = 1.52[/tex]

(b) Find the approximate sample standard deviation, s.

Standard deviation of the sample.

Square root of the sum of the squares of the values subtracted from the mean, divided by the sample size subtracted by 1. So

[tex]s = \sqrt{\frac{5*(0-1.52)^2 + 9*(1-1.52)^2 + 5*(2-1.52)^2 + 5*(3-1.52)^2 + 1*(4-1.52)^2}{24}} = \sqrt{\frac{32.24}{24}} = 1.16[/tex]

Answer:

Step-by-step explanation:

1). System of equations is,

  -2x - y = -22 -------(1)

   4x - 8y = 4 -------(2)

   By satisfying these equations with the given point (9, 4),

  Equation (1)

  -2(9) - 4 = -22

  -18 - 4 = -22

  -22 = -22

  True.

  Equation (2)

  4(9) - 8(4) = 4

  36 - 32 = 4

  4 = 4

  True.

  Given point lies on both the equations.

  Therefore, the given point is the solution of the system of equations.

2). 3x - 3y = 27 -----(1)

  -2x + 9y = -11 ------(2)

  Satisfy the equations with the given point (-10, -1)

  Equation (1)

  3(-10) - 3(-1) = 27

  -30 + 3 = 27

   -27 = 27

   False.

  Equation (2)

  -2x + 9y = -11

  -2(-10) + 9(-1) = -11

   20 - 9 = -11

   11 = -11

   False.

  Therefore, the given point is not the solution of the system of equations given.

Answer:

the equation is p=8m. x=24

Step-by-step explanation:

The value of p is 8 times greater than m. So 8 times greater than 3 is 24.

Answer:

The system that can be used is:

[tex]10x + 2y = 56[/tex]

[tex]9x + 3y = 60[/tex]

Step-by-step explanation:

We have that:

x is the price of a package of sugar cookies, y is the price of a package of oatmeal cookies.

Shaikha sold 10 packages of sugar cookies and 2 packages of oatmeal cookies for $56.

This means that:

[tex]10x + 2y = 56[/tex]

Khalid sold 9 packages of sugar cookies and 3 packages of oatmeal cookies for $60.

This means that [tex]9x + 3y = 60[/tex]

System that can be used:

The system that can be used is:

[tex]10x + 2y = 56[/tex]

[tex]9x + 3y = 60[/tex]

We have that what  13%, 10%, 0.125, and 1/5 have in common​ is

These are all numbers less than 1 as the are all decimal of "0."

From the Question we are told that

13%, 10%, 0.125, and 1/5 are number given

We must note that

These are all numbers less than 1 as the are all decimal of "0."

13%, =0.13

10%, =0.10

0.125,=0.125

1/5=0.2

Answer:

the principal balance at the beginning of June is $22,222.22

Step-by-step explanation:

The computation of the principal balance at the beginning of June is shown below:

Principal balance = Interest paid ÷ (Interest Rate ÷ 12 Months)

= $250 ÷ (13.5% ÷ 12)

= $22,222.22

Hence, the principal balance at the beginning of June is $22,222.22

Answer:

x<2

Step-by-step explanation:

Hello There!

Our objective for this problem is to isolate the variables

To do so we use inverse operations

x+4<6

subtract 4 from each side

4-4 cancels out

6-4=2

we're left with

x<2

Step-by-step explanation:

It is just like a normal x equation just with an inequality. So for now, just represent the < as and =

so we have x+4=6

subtract 4 from both sides

x+4-4=6-4

x=2

Now we insert the <

x<6

so all values for x are all less than 6

Hope that helps :)

Answer:

Step-by-step explanation:

Note that the two equations are equivalent.

2y = 14-2x can be rearranged to y = -x+7, which is the same as the second equation. What you're looking is one line on top of the other.

Every shared point is a solution. Since there are infinitely many points on a line, and these lines share every point, there are infinitely many solutions.

Answer:

Step-by-step explanation:

Hello There!

So if you didn't know an exterior angle of a triangle is equal to the two opposite interior angles of a triangle

So basically

∠XYZ=∠WXY+∠XWY

so to find ∠XWY we subtract the value of ∠WXY (45) from the value of the exterior angle (115)

115-45=70 so ∠XWY=70

Answer:

?+45=115° sum of two interior angle of the triangle is equal to the exterior angle

<XWY=115-45=70
