What is the change in the y-values and x-values on the graph? a. The change in the y-values is 40 and the change in the x-values is 1 B. The change in the y-values is 1 and the change in the x-values is 40 C. The change in the y-values is 150 and the change in the x-values is 2. D. The change in the y-values is 190 and the change in the x values is 3

Answer:

B.  y ≤ 1/2x + 3

Step-by-step explanation:

Well we can start by finding the y-intercept which is the point on the line that touches the y-axis in this case it’s 3.

And by looking at the shade it is facing down and the line is solid so the inequality starts with y ≤,

So we can cross out answer choices C. and D.

And the slope is 1/2 because that’s how far away each points are from each other.

So the inequality is y ≤ 1/2x + 3

Look at the image below.

Answer:

Option B is the correct answer

Step-by-step Explanation:

[tex] \sin 45 \degree = \frac{x}{2} \\ \\ \frac{1}{ \sqrt{2} } = \frac{x}{2} ..( \because \: \sin 45 \degree =\frac{1}{\sqrt 2}) \\ \\ \huge \purple{ \boxed{ x = \frac{ \sqrt{2} }{2}}} \\ \\ [/tex]

Using the trigonometric ratio sine, we find that x = [tex]\sqrt{2}[/tex], making option D to be correct.

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). These trigonometric ratios deduce a relationship between angles of right angle triangle ( other than the right angle ) and the sides of the triangle : base, perpendicular, hypotenuse.

We have used trigonometric ratio sine here.

sin[tex]\theta[/tex] = [tex]\frac{perpendicular}{hypotenuse}[/tex]

In the given question,

from the point of view of angle 45° which is marked in the figure,

base = y

perpendicular  = x

hypotenuse = 2

Using, sin[tex]\theta[/tex] =  [tex]\frac{perpendicular}{hypotenuse}[/tex]

sin 45 = [tex]\frac{2}{x}[/tex]

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

Well for the activity we can do a game.

In a game you start with 50 coins and everytime you kill a monster "x" you get 2 more coins.You need 100 coins to level up.

We can make the following inequality,

2x + 50 ≥ 100

So to find x we single it out,

2x + 50 ≥ 100

-50 to both sides

2x ≥ 50

Divide 2 by both sides

x ≥ 25

For the number line look at the image below ↓

The solution in the number line is the number of monsters killed in order to level up.

Answer: Associative Property: (40+(12+18)+27. Evaluate: 97

Answer:

See below.

Step-by-step explanation:

6 - 23(x+5) = 4x

First, distribute.

6 - 23x - 115 = 4x

Reorder the terms.

6 - 115 - 23x = 4x

Subtract.

-109 -23x = 4x

Add 23x to both sides.

-109 = 27x

Divide by 27.

x = -109/27 (This cannot be simplified)

Answer:

m=4

Step-by-step explanation:

6.33 × 10^9 / 1.79 × 10^5=3.54 × 10^m

Find m

6.33 × 10^9 / 1.79 × 10^5 =3.54 × 10^m

Divide the multipliers

6.33/1.79

=3.54

Divide the other multipliers

10^9/10^5

Division in scientific notation with superscript with the SAME base requires subtraction of the superscript using one of the bases

10^9/10^5

= 10^9-5

=10^4

Therefore,

6.33 × 10^9 / 1.79 × 10^5 = 3.54 × 10^4

m = 4

Answer:

Cos E= 24/25

Step-by-step explanation:

Length of hypotenuse: 7^2+24^2=625. 625 square root=25

Thus, DE is 25.

Sin D= 24/25, so that is false.

Tan D= 24/7, so that is false.

Cos E= 24/25, so that is true

Sin E= 7/25, so that is false.

Total number of side of regular polygon = 36

Step-by-step explanation:

Given:

Angle of rotation (regular polygon) = 10°

Find:

Total number of side of regular polygon

Computation:

Total number of side of regular polygon = 360° / Angle of rotation (regular polygon)

Total number of side of regular polygon = 360° / 10°

Total number of side of regular polygon = 36

Answer:

The sum of the polynomials in the equation is 3x² - 2x - 3

Step-by-step explanation:

(3 - 4x + 8x²) + (-6 + 2x - 5x²)

Distribute the positive sign to (-6 + 2x - 5x²). So all of these terms will stay the same and maintain their original signs.

3 - 4x + 8x² - 6 + 2x - 5x²

Combine like terms.

- 3 - 2x + 3x²

Now put the equation in standard form. This means that the exponential numbers will be ordered in descending order.

3x² - 2x - 3

Answer:

3x^2 -2x -3

Step-by-step explanation:

Combine like terms

3-4x+8x^2-6+2x-5x^2

Put the numbers that are squared in the front

8x^2 -5x^2 =3x^2

Put the numbers with x only next

-4x + 2x= -2x

Then the normal numbers

3-6=-3

Put them together in simplified form of the equation

Thus your answer is 3x^2 - 2x -3

Answer:

Adults = 61

Students = 92

Children = 122

Step-by-step explanation:

a adults

x students

c children

a + c + x = 275

c / a = 2

5c + 7x + 12a = 1986

Simplify and solve the system.

a + 2a + x = 275

3a +x = 275

x = 275 - 3a. and c= 2a

The revenue equation can be written in terms of just one variable, a.

5(2a) + 7(275-3a) + 12a = 1986

Solve for a

a = 61

use it to find x and c.

c = 2a = 2 x 61 = 122

x = 275-a-c

x = 275 - 61-122

x = 92

Answer: 18 animals

Step-by-step explanation:

3 out of 20 pet owners get their pet from a breeder.

To find how many animals have been bought from a breeder, you need to find 3/20 of the 122 animals.

3/20 = 0.15

122 * 0.15 = 18.3

18.3 rounds down to 18

There are 18 animals who have been bought from a breeder.

Answer:

centre: (0, 0)

radius: 3√5 ≈ 6.71

Step-by-step explanation:

The equation of a circle is denoted by:

[tex](x-x_1)^2 +(y-y_1)^2=r^2[/tex], where [tex](x_1,y_1)[/tex] is the centre and r is the radius

Here, we see that x1 and y1 are each 0, which means the centre is (0, 0).

We also see that r² = 45, which means the radius is r = √45 = 3√5 ≈ 6.71.

Therefore, we want to draw a circle with radius 6.71 and centre at (0, 0). See attached.

Answer:

  H.  48

Step-by-step explanation:

Let p represent the number of coins Pamela has. Then 3p is the number Samantha has. After 6 days of adding coins, we have ...

  2(p +3·6) = 3p +2·6

  2p +36 = 3p +12

  24 = p . . . . Pamela has 24 coins; Samantha has 72.

Now, we can find the number of days (d) before the coin count is the same.

  24 +3d = 72 +2d . . . . coin counts are the same after d days

  d = 48 . . . . . subtract 24+2d

In 48 days from now, Pamela and Samantha will have the same number of coins.

Answer:

y = -2

Step-by-step explanation:

Put x as -19 and solve for y.

2(-19) - 5y = -28

Multiply.

-38 - 5y = -28

Add 38 on both sides of the equation.

-5y = -28 + 38

-5y = 10

Divide both sides by -5.

y = 10/-5

y = -2

Answer:

2x - 5y = -28

when x = - 19

Substitute the value of x into the equation

That's

2(-19) - 5y = -28

-38 - 5y = -28

-5y = -28 + 38

-5y = 10

Divide both sides by - 5

We get

y = 10/-5

y = -2
