Is (4, -2) a solution of the inequality? Why or why not?

Answer:

1/8

Step-by-step explanation:

x-8y=-1

First, put the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)

-8y = -x-1

y = 1/8x +1/8

The slope is 1/8 and the y intercept is 1/8

The slope for parallel lines is the same for all parallel lines

have a good day :)

The number of minutes it would take Athlete J to run one mile is 12 minutes.

The number of hours it would take Athlete h to run 5 miles is 10/11 hour.

Athlete h runs faster because his average speed is greater than that of  Athlete J.

In order to determine the time it would take Athlete J to run one mile, the average speed has to be determined.

Average speed = total distance / time

2/3 ÷ 8

2/3 x 1/8 = 1/12 mile / minute

Time it would take Athlete J to run one mile = distance / speed

1 ÷ 1/12 = 12 minutes

Average speed of Athlete H = 2 3/4 ÷ 1/2

11/4 x 2 = 5 1/2 miles / hour

Time it would take Athlete H to run 5 miles = distance / speed

5  ÷ 11/2

5 x 2/11 = 10/11 hours

Step-by-step explanation:

m∠2 = m∠4

y + 10 = 3y - 24

y - 3y = -24 - 10

-2y = -34

y = -34/-2

y = 17

m∠2 = y + 10

m∠2 = 17 + 10

m∠2 = 27°

-2-2=0.5(3-5)

OR (-2-2)=1/2(3-5)

Uisng the ratio concept, the number of charms that should be put into each group would be 12 and 18 respectively

Given the Parameters :

The group with 2 :

[2 ÷ (2+3)] × 30

(2 / 5) × 30

= 12

The group with 3 :

[3 ÷ (2+3)] × 30

(3 / 5) × 30

Answer:

+ or - 11

Step-by-step explanation:

To find the square root of 121, think of a number that multiplied by itself would get to 121. This number is 11. However, do remember that the number could also be negative 11 bencause a negative times a negative becomes positive.  I would advise you to try memorizing the squares of 0 to 15 to help you with this. Otherwise, you can just use a calculator.

Hope this helps! :)

Answer:

Radius = 7cm , Circumference = 43.96cm

Step-by-step explanation:

To find the radius, you divide the diameter by 2.

14 / 2 = 7cm

To find the circumference, you multiply 兀 ( 3.14 ) with the diameter

兀d = 兀 x 14 = 43.96cm

Answer:

218

-72

12° C

Step-by-step explanation:

The magnitude of a single number is the positive version of that number.

We write it mathematically like this:

|−218|=218

|-12|=12

The magnitude of a number is also known as the absolute value, and literally means the 'size' of the number, not worrying if it is positive or negative.

For numbers such as 1, 2, 3, and so on, the magnitude is simply the number itself. If the number is negative, the magnitude becomes the absolute value of the number. For example, the magnitude of 10 is 10. The magnitude of -10 becomes the absolute value of -10, which is 10.

Using implicit differentiation, it is found that she must blow air at a rate of 251.33 cm³/sec.

The volume of a sphere of radius r is given by:

[tex]V = \frac{4\pi r^3}{3}[/tex]

The radius is half the diameter, hence:

[tex]r = \frac{d}{2}[/tex]

[tex]r^3 = \frac{d^3}{8}[/tex]

[tex]V = \frac{4\pi d^3}{24} = \frac{\pi d^3}{6}[/tex]

Applying implicit differentiation, the rate of change of the volume is:

[tex]\frac{dV}{dt} = \frac{d^2 \pi}{2}\frac{dd}{dt}[/tex]

The rate that she must blow air is:

[tex]\frac{dV}{dt} = \frac{d^2 \pi}{2}\frac{dd}{dt}[/tex]

[tex]\frac{dV}{dt} = \frac{4^2 \pi}{2}(10)[/tex]

[tex]\frac{dV}{dt} = 251.33[/tex]

She must blow air at a rate of 251.33 cm³/sec.

Answer:

Step-by-step explanation:

- 38d - 57 ≥ - 19d + 76

- 38d + 38d - 57 - 76 ≥ - 19d + 38d + 76 - 76

-133 ≥ 19d

-133/19 ≥ 19/19d

-7 ≥ d

Answer:

[tex]d\leq -7[/tex]

Step-by-step explanation:

Move all terms containing [tex]d[/tex] to the left side of the inequality.

Add [tex]-19d[/tex] to both sides of the inequality.

[tex]-38d-57+19d\geq 76[/tex]

Add [tex]-38[/tex] and [tex]19d.[/tex]

Move all terms not containing  [tex]d[/tex]  to the right side of the inequality.

Add [tex]57[/tex] to both sides of the inequality.

[tex]-19d\geq 76+57[/tex]

Add [tex]76[/tex] and [tex]57.[/tex]

[tex]-19d\geq 133[/tex]

Divide each term by [tex]-19[/tex] and simplify.

Divide each term in [tex]-19d\geq 133[/tex] by [tex]-19[/tex]. When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

[tex]\frac{-19d}{-19} \leq \frac{133}{-19}[/tex]

Cancel the common factor

[tex]\leq \frac{133}{-19}[/tex]

Divide [tex]133[/tex] by [tex]-19.[/tex]

[tex]d\leq -7[/tex]

The result can be shown in multiple forms.

Go to demose and plug it in it worked for me but it wont let me out a link in my awnser.

Answer:

Step-by-step explanation:

Let width = w

Length = w - 7

Perimeter = 2*(length + width)

2*(w-7 + w) = 50

2* (2w - 7) = 50

2*2w - 7*2 = 50

4w - 14 = 50

Add 14 to both the sides

4w = 50+ 14

4w = 64

Divide the entire equation by  4

w = 64/4

w = 16 units

Length = 16 - 7 = 9 units
