y = −2x + 11
y = −2x − 5

Answer:

there are 97 + 47 + 77 = 221 creatures from Earth in the alien spaceship.

the probability that a human being is chosen at random = 77 / 221 = 0.3484 = 34.84%

the probability that a chicken is chosen at random = 97 / 221 = 0.4389 = 43.89%

the probability of choosing a cow at random = 100% - 34.84% - 43.89% = 21.27%

Answer:

B; 4/d-6

Step-by-step explanation:

We want to perform a division here

Flipping the right hand side while changing the sign to multiplication, we have that;

(2d - 6)/ (d^2 + 2d -48) * (2d + 16)/d-3

= 2(d-3)/(d^2 + 2d - 48) * 2d + 16/d-3

= 2/(d^2 + 2d - 48) * 2d + 16/1

2/(d-6)(d + 8) * 2(d + 8)/1

= 2/d-6 * 2/1

= 4/d-6

Answer:

The answer is 18 -12x = -12x + 18

Answer:

y=-5x+5

Step-by-step explanation:

y=mx+b

m = slope which is 5 going down, so -5

b = y intercept which is 5

Answer:

Kayla is correct

Step-by-step explanation:

For a vertical line, the x-value is the same

This means there is no change in the x value

A slope is calculated by dividing by the change in x value

since in this case , we will be dividing by zero, it means that the value of our slope is going to be undefined

This means that Kayla is correct

Answer:

1.7 m/s

Step-by-step explanation:

1/3 mile = 536 m

1/12 hour = 5 minutes = 300 second

volecity = s/t = 536 / 300 = 1.7 m/s

9514 1404 393

Answer:

  4 miles per hour

Step-by-step explanation:

Speed is the ratio of distance to time:

  speed = miles/hours = (1/3)/(1/12) = (4/12)/(1/12) = 4/1 = 4

Mr. M's walking speed is 4 miles per hour.

Answer:

2/3

Step-by-step explanation:

Firstly we get the y value at both x points

At x = 1

y = 2/3 + 1/2 = (4 + 3)/6 = 7/6

At x = 2

y = 4/3 + 1/2 = (8 + 3)/6 = 11/6

The slope formula is

m = (change in y)/change in x

The slope is thus;

(11/6-7/6)/(2-1) = 4/6 = 2/3

What interest is this. Simple or compound? Cause both have different formulas.

Simple interest

A(interest) = (Principal× Rate×time)

A= (P ×3×2years)/100%

$45 = 6/100P

4500= 6p

4500/6 = P

principal= $750.

Answer:

f(x) = -1/x

Step-by-step explanation:

Here, we want to find the function that is not linear

A linear function is of the form;

y = mx + b

where m can be zero, or b can be zero

The only option that does not follow this description is

f(x) = -1/x

Answer:

7). x = 6, [tex]\frac{14}{3}[/tex]

8). x = 2

Step-by-step explanation:

7). Area of a circle = πr²

   Here 'r' = radius of the circle

Area of the shaded region of the circle = Area of the large circle - Area of the small circle

                                                                 = π(x)² - [tex]\pi (\frac{x}{2})^2[/tex]

                                                                 = [tex]\pi x^{2} -\pi (\frac{x^2}{4})[/tex]

                                                                 = [tex]\pi x^{2}(1-\frac{1}{4})[/tex]

                                                                 = [tex]\frac{3\pi x^{2} }{4}[/tex] in²

If area of the shaded region is (8πx - 21π) in²

[tex]\frac{3\pi x^{2} }{4}=8\pi x - 21\pi[/tex]

[tex]\frac{3x^2}{4}=8x-21[/tex]

3x² = 32x - 84

3x²- 32x + 84 = 0

3x² - 14x - 18x + 84 = 0

x(3x - 14) - 6(3x - 14) = 0

(x - 6)(3x - 14) = 0

x = 6, [tex]\frac{14}{3}[/tex]

8). Area of the shaded region = Area of the largest circle - Area of the smaller semicircle - Area of the smallest semicircle

Area of the largest circle = π(2x + 2x)²

                                         = 16πx²

Area of the smaller semicircle = [tex]\frac{1}{2}\pi (3x)^{2}[/tex]

                                                  = 4.5(πx²)

Area of the smallest semicircle = [tex]\frac{1}{2}\pi (2x)^{2}[/tex]

                                                    = 2πx²

Now area of he shaded region = 16πx² - [4.5(πx²) + 2πx²]

                                                    = 16πx² - 6.5πx²

                                                    = 9.5πx² mm²

If the area of the shaded region = 12πx + 14π

12πx + 14π = 9.5πx²

12x + 14 = 9.5x²

9.5x² - 12x - 14 = 0

19x² - 24x - 28 = 0

19x² - 38x + 14x - 28 = 0

19x(x - 2) + 14(x - 2) = 0

(19x + 14)(x - 2) = 0

x = [tex]-\frac{14}{19},2[/tex]

But the radius o a circle can't be negative.

Therefore, x = 2 will be the answer.

Assuming Adams amount is x, three times his amount will be 3x. $14 more than the times Adam's amount will be 14 +3x.

Therefore if Arlene's money is $56 which is $14 more than three times Adam's amount, then the equation will be ;

14+3x=56

Answer:

The value of a is 25

Step-by-step explanation:

When two angles are supplementary, they add up to 180 degrees

Mathematically,

(30 + 2a) + (125-a) = 180

30 + 2a + 125 - a = 180

a + 155 = 180

a = 180-155

a = 25 degrees

5 Bags = 61.5 Ounces

123 Ounces = 10 Bags

Step-by-step explanation:

24.6 divided by 2 is 12.3.

12.3 times 5 is 61.5

Answer:

Step-by-step explanation:

SOHCAHTOA, we use the toa part

tan(24)=x/12

Answer:

RS = XY (since the two a triangles are similar, you have to match the sides up and then set the values equal to eachother to find the value of x)

3x +2 = 5x -3 (subtract 5x from both sides)

-2x +2 = -3 (subtract 2 from both sides)

-2x = -5 (divide both sides by -2 to isolate x)

x = 2.5 (take the value of x and plug it into the expression given for RS)

3(2.5) +2 (multiply)

7.5 +2 (add)

9.5 (this is the length of RS)
