Find the slope of a line perpendicular to the equation 3x-y=6

Answer:

x=19

Step-by-step explanation:

The perimeter of the right triangle is

P=9+12+15 =36

The perimeter of the left triangle is

P =x-7+ x-7+ x-7 = 3x-21

Set them equal

36 = 3x-21

Add 21 to each side

36+21 = 3x-21+21

57 = 3x

Divide each side by 3

57/3 = 3x/3

19 =x

Answer:

[tex]x=19[/tex]

Step-by-step explanation:

The perimeter of a shape is the sum of all of its side lengths. Therefore, the perimeter of the first triangle is [tex]x-7+x-7+x-7=3x-21[/tex] and the perimeter of the second triangle is [tex]9+15+12=36[/tex].

We are given that the perimeters of the triangles are equal, so [tex]3x-21[/tex] equals [tex]36[/tex]. As an equation, that would be [tex]3x-21=36[/tex]. Solving for [tex]x[/tex], we get:

[tex]3x-21=36[/tex]

[tex]3x=57[/tex] (Add [tex]21[/tex] to both sides of the equation to isolate [tex]x[/tex])

[tex]x=19[/tex] (Divide both sides of the equation by [tex]3[/tex] to get rid of [tex]x[/tex]'s coefficient)

Step-by-step explanation:

They are adjacent angles.

Adjacent angles are right next to each, or side-by-side. Considered (by my math teacher) the next door neighbors.

The answer is 3. Choosing from 3 red marbles, 4 yellow marbles, and 8 blue marbles. The model provides an accurate representation of the items in the bag as each item is equally likely to be chosen.

It is used in a variety of activities such as rolling dice games, probability experiments, and math activities.

The model of flipping a coin fifteen times is incorrect as it does not accurately represent the scenario. There is no representation of the different sports items in the bag.

The model of spinning a spinner with three equal sections is incorrect as the items in the bag are not equal and there are three sections in the spinner.

The model of rolling a number cube labeled one through six fifteen times is incorrect as the number cube does not accurately represent the sports items in the bag.

In conclusion, the best model to simulate the scenario with a sports bag containing 3 tennis balls, 4 baseballs, and 8 golf balls is 3. Choosing from 3 red marbles, 4 yellow marbles, and 8 blue marbles.

6(7x) + 6(10) Distribute

42x + 60 Simplify

Answer:

6(7x+10)

Step-by-step explanation:

Hello There!

We can find an equivalent expression by factoring

First we need to find the greatest common factor (GCF)

GFC - largest number that both numbers can be divided by

Lets write down all of the multiples of each number

42 - 42 and 1, 21 and 2, 13 and 3, 6 and 7,

60 - 60 and 1, 30 and 2, 20 and 3, 4 and 15, 6 and 10

Then we find the greatest common factor which would be 6

42x/6=7x

60/6=10

so we can conclude that an equivalent expression would be

6(7x+10)

Question:

The velocity function, in feet per second, is given for a particle moving along a straight line. [tex]v(t) = t^2 - t - 42[/tex]    [tex]1 \le t \le 12[/tex]

Find the displacement

Answer:

The displacement is 42.17ft

Step-by-step explanation:

Given

[tex]v(t) = t^2 - t - 42[/tex]    [tex]1 \le t \le 12[/tex]

The displacement x, is calculated using:

[tex]x = \int\limits^a_b {v(t)} \, dt[/tex]

[tex]x = \int\limits^{12}_{1} {t^2 - t - 42} \, dt[/tex]

Integrate

[tex]x = \frac{1}{3}t^3 - \frac{1}{2}t^2 - 42t|\limits^{12}_{1}[/tex]

Substitute 12 and 1 for t respectively

[tex]x = (\frac{1}{3}*12^3 - \frac{1}{2}*12^2 - 42*12) - (\frac{1}{3}*1^3 - \frac{1}{2}*1^2 - 42*1)[/tex]

[tex]x = (576 - 72 - 504) - (\frac{1}{3} - \frac{1}{2} - 42)[/tex]

[tex]x = (0) - (-42.17)[/tex]

[tex]x = 42.17[/tex]

Answer:

294

Step-by-step explanation:

14 x 9 = 126

so the area of your rectangle is 126.

15 - 9 = 6

so 6 is the width, 14 is the height.

14 x 6 = 84

now you have to multiply is by 2, because there is still another Triangle on the other side.

84 x 2 = 168

Now you take 168 and 126 and add your areas, and you have found the complete area!

168 + 126 = 294

Answer:

∠1 = 48°

∠2 = 132°

∠3 = 48°

Step-by-step explanation:

∠1 = (360-132-132)/2 = 48°

∠2 = 132° because it is the alternate angle to 132°

∠3 = 48° because it is the alternate angle to ∠1

Answer:

-6 and 7

Step-by-step explanation:

x is one number and y is the other

(1)-----------------    8x+5y=-13

(2)------------------  x+y= 1

first, let multiply both sides of (x+y=-1) by 8

(3)-----------------    8x+8y=8

lets subtract (1) from (3)

(8x+8y)-(8x+5y)=8-(-13)=3y

8-(-13)=3y ->  21=3y

y=7

lets plug in 7 into (2) for x

x+7=1

x=-6

the numbers are -6 and 7

Answer:

50272

Step-by-step explanation:

Okay how I solve these equations is I take the problem apart like this:

3142 = 3000 + 100 + 40 + 2

Now we multiply each number by 16:

3000 * 16 = 48000

100 * 16 = 1600

40 * 16 = 640

2 * 16 = 32

Then we add all the totals together:

48000 + 1600 + 640 + 32 = 50272
