What’s the range? 10 points ! !

Answer:

x > -11

Step-by-step explanation:

Step 1: Write inequality

x + 3 > -8

Step 2: Solve for x

Here, the inequality is saying that any number greater than -11 will work as a solution.

Answer:

1.

8x + 6y = 28

9x + 3y = 39

Set to equal y.

8x + 6y = 28

6y = -8x + 28

y = -8/6x + 28/6

y = -4/3x + 14/3

9x + 3y = 39

3y = -9x + 39

y = -9/3x + 39/3

y = -3x + 13

Set equal to each other.

-4/3x + 14/3 = -3x + 13

Combine like terms.

5/3x = 25/3

Multiply by 3/5

x = 5

Plug x in.

y = -3(5) + 13

y = -15 + 13

y = -2

(5, -2)

2.

-2x - 9y = -3

-7x - 9y= -33

Set equal to y.

-2x - 9y = -3

-9y = 2x - 3

y = -2/9x + 3/9

y = -2/9x + 1/3

-7x - 9y= -33

-9y = 7x - 33

y = -7/9x + 33/9

y = -7/9x + 11/3

Set equal to each other

-2/9x + 1/3 = -2/9x + 1/3

0 = 0

infinitely many solutions

Distributive Property

Answer:

The true statements are;

A. m∠6 = 55°

C. m∠1 + m∠4 = 250°

D. m∠1 + m∠6 = m∠7 + m∠4

Step-by-step explanation:

The given information are;

m∠7 = 55°

The angles formed by the transversal and the upper horizontal parallel line are (starting from the top left and moving in clockwise direction) = 1, 2, 4, 3

Similarly, the angles formed by the transversal and the lower horizontal parallel line are (starting from the top left and moving in clockwise direction) = 5, 6, 8, 7

Therefore, we have;

m∠7 ≅ m∠6 (Vertically opposite angles are congruent)

∴ m∠6 = m∠7 = 55°

m∠6 = 55° which corresponds with option A.

m∠5 + m∠6 = 180° (The sum of angles on a straight line)

∴ m∠5 = 180° - m∠6 = 180° - 55° = 125°

m∠5 = 125°

m∠1 ≅ m∠5 (Corresponding angles)

∴ m∠1 = m∠5 = 125°

m∠1 ≅ m∠4 (Vertically opposite angles)

∴ m∠1 = m∠4 = 125°

∴ m∠1 + m∠4 = 125° + 125° = 250°

m∠1 + m∠4 = 250° which corresponds with option C.

m∠1 ≅ m∠4 (Vertically opposite angles)

m∠6 ≅ m∠7 (Vertically opposite angles)

∴ m∠1 + m∠6 = m∠7 + m∠4 (Transitive property) which corresponds with option D.

Step-by-step explanation:

Answer:

(1 + tanθ) / (1 + cotθ) = (1 + sinθ / cosθ) / (1 + cosθ / sinθ)

(1 + tanθ) / (1 + cotθ) = ((cosθ + sinθ) / cosθ) / ((sinθ + cosθ) / sinθ)

(1 + tanθ) / (1 + cotθ) = (1 / cosθ) / (1 / sinθ)

(1 + tanθ) / (1 + cotθ) = secθ / cscθ

Answer:

n=0

Step-by-step explanation:

both numbers have the same bases which is 5 so we can say that their exponents are equal to each other:

-2n = -2n-3

now we isolate the n variables to one side:

-2n + 2n = -3

0n = -3

n = 0

Answer:

g(6) = 31

Step-by-step explanation:

If g(x) = x^2 - 5, that means to solve for g(6) you just have to replace the x in the equation with 6.

g(6) = 6^2 - 5

g(6) = 36 - 5

g(6) = 31

The range from the graph is all Real numbers

Given parameters:

We have two shapes, the rectangle and semi circle;

   The problem is to find the perimeter of the shape given

The perimeter of a body is the total length of the body.

 Here, it is the sum of the perimeter of the rectangle and semi-circle.

Note, to remove repetition, we to deduct 6 which is a common point to both of them.

Perimeter of a semi-circle = Circumference of semi- circle

                                            = πr² x [tex]\frac{1}{2}[/tex]

         The diameter here is 6 and radius is 3;

        Circumference of semi-circle = π x 3² x [tex]\frac{1}{2}[/tex]  = 14.14

Perimeter of rectangle = 2(6+8) = 28

The perimeter of the figure = 14.14 + 28 - 6 = 36.1

The perimeter of the figure is 36.1

Answer:

The given data can be written in the form of an AP, where n is the number of songs Hailey downloads

song_bill(n) = 14 + n(1.50)

Money Hailey has to pay after downloading 40 songs:

n = 40

song_bill(40) = 14 + 40(1.5)

song_bill(40) = 14  + 60

song_bill(40) = 74 dollars

Money Hailey has to pay after downloading ss songs:

n = ss

song_bill(ss) = 14 + ss(1.5)

song_bill(ss) = 14 + 1.5(ss) dollars

We need to write and solve an algebraic equation to find the final company's balance.

The answer is: The final balance is -$275.

Let's see how to get that.

First, we know that the company earns $150 per week for 9 weeks, then the total amount of money that the company earns in these 9 weeks is:

$150*9 = $1,350

Then the company losses $65 per week for 25 weeks, then the amount that the company losses is:

$65*25 = $1,625

The final balance will be the difference between what the company earned and what the company lost, then the final balance is:

balance = $1,350 - $1,625 = -$275

This means that the company's final balance is -$275.

Answer:

[tex]\left\{ \begin{array}{ll} a+s+r=350 \\ 4a+2.5s+2r=1095\\r=s-40 \end{array} \right.[/tex]

Step-by-step explanation:

Let's define our variables. Let a represent the number of adult tickets sold, s represent the number of senior tickets sold, and r represent the number of senior tickets sold.

We know that a total of 350 tickets were sold. So, the number of adult, student, and senior tickets sold must total 350. Therefore, we can write the following equation:

[tex]a+s+r=350[/tex]

We know that each adult ticket costs $4, each student ticket costs $2.50, and each senior ticket costs $2. We are given that a total of $1095 was collected. Therefore, the number of tickets multiplied by their respective price must equal $1095. So, we can write the following equation:

[tex]4a+2.5s+2r=1095[/tex]

Finally, we know that 40 fewer senior tickets were sold than student tickets. So, however many students tickets were sold, we can subtract 40 to get the number of senior tickets sold. Therefore:

[tex]r=s-40[/tex]

So, our system of equations is:

[tex]\left\{ \begin{array}{ll} a+s+r=350 \\ 4a+2.5s+2r=1095\\r=s-40 \end{array} \right.[/tex]

And we're done!
