Answer:

The slope of the line on the graph is [tex]\frac{3}{2}[/tex].

Step-by-step explanation:

The slope of a line can be found with [tex]\frac{\Delta y}{\Delta x}[/tex]. The points (3,2) and (-1,-4) lie on the line, so we can subtitute [tex]\Delta y = -4 -2 = -6[/tex] and [tex]\Delta x = -1-3 = -4[/tex] to see that the slope equals [tex]\frac{-6}{-4} = \frac{3}{2}[/tex]. This answer makes sense because the slope is going up when [tex]x[/tex] becomes larger (the slope is positive), and we travel more in the [tex]y[/tex]-direction than in the [tex]x[/tex]-direction (the slope is greater than 1).

Answer:

I. Mean = 15

II. Median = 15

Step-by-step explanation:

Given the following data;

Total number of students = 8

x = 18, 10, 20, 18, 12, 19,12, 11

F(x) = 18 + 10 + 20 + 18 + 12 + 19 + 12 + 11

F(x) = 120

To find the mean;

Mean = F(x)/n

Mean = 120/8

Mean = 15

To find the median;

Median refers to the middle number of a sorted data.

x = 10, 11, 12, 12, 18, 18, 19, 20

Middle numbers = 12 and 18

Median = (12 + 18)/2

Median = 30/2

Median = 15

They start you off with the angle 122 d (degrees) and a straight lime is 180 d so you should do 180 d - 122 d to get 58

Answer:

-3s^2+16s-7

Step-by-step explanation:

-3s(s - 10) + 7(-2s -1)​ --> (-3s^2+30s)+(-14s-7) ---> -3s^2+16s-7

DO multiplication them convert like terms

Answer:

-3s² + 16s - 7

Step-by-step explanation:

Remember to follow FOIL. FOIL stands for (First, Outside, Inside, Last).

First, distribute -3s to s and -10, and 7 to -2s and -1:

-3s(s - 10) = -3s² + 30s

7(-2s - 1) = -14s - 7

Next, combine like terms:

-3s² + 30s - 14s - 7

-3s² + (30s - 14s) - 7

-3s² + 16s - 7

-3s² + 16s - 7 is your answer.

The value of x for which equation 0.75(x + 20) = 2 + 0.5(x - 2) becomes true is equal to -56.

An equation is given which is 0.75(x + 20) = 2 + 0.5(x - 2).

We have to find out the value of x for which the equation becomes true.

What do you mean by algebraic expressions ?

The algebraic expressions are those which are made up of variables, constants and algebraic operations i.e., addition, subtraction, etc.

As per the question ;

The equation given is 0.75(x + 20) = 2 + 0.5(x - 2)

Let's solve to get the value of x.

⇒ 0.75(x + 20) = 2 + 0.5(x - 2)

⇒ 0.75x + 15 = 2 + 0.5 x - 1

⇒ 0.75x - 0.5x = 1 - 15

⇒ 0.25x = - 14

⇒ x = -14 ÷ 0.25

⇒ x = - 56

Let's check ;

0.75(x + 20) = 2 + 0.5(x - 2)

0.75 ( -56 + 20 ) = 2 + 0.5 ( -56 - 2 )

(0.75 × -56) + (0.75 × 20) = 2 + (0.5 × -56) + (0.5 × -2)

-42 + 15 = 2 -28 - 1

-27 = -27

Both sides are equal for value of x = -56.

Thus , the value of x for which equation 0.75(x + 20) = 2 + 0.5(x - 2) becomes true is equal to -56.

The Surface Area of a Cuboid

Given a cuboid (rectangular prism) of dimensions x,y, and z, the surface area is calculated as follows:

[tex]S=2(xy+yz+xz)[/tex]

The dimensions of a given cuboid are x=28 cm, y=4 cm, z=5 cm, thus:

[tex]S=2(28*4 + 4*5+ 28*5)[/tex]

[tex]S= 2*272 = 544[/tex]

The surface area is [tex]544 cm^2[/tex]

Step-by-step explanation:

If you have 8 loins and 4 tigers you add those up, you now have 12, if you have 24 cats that means that you double that, 12 x 2 =24 (boom) so now you know you just have to double 4 into 8.

Because for every 8 loins there are there are 4 tigers.

Answer:

D

Step-by-step explanation:

The slope of the graph would be negative and constant for 12 s; then, the slope would be 0 for 6 s because the slope represents the passing of time. Therefore, option D is the correct answer.

Velocity gives us information about the rate of change of your position, meaning how fast your position is changing per unit time.

Given that, a bus increases its position at a constant velocity for 12 s, and then it stops for 6 s.

Here, rate of change is 12/6 = 2 s

Therefore, option D is the correct answer.

Answer:

m = -35/49

c = -48

y = -35/49 x - 48

Step-by-step explanation:

Given the coordinate point

(-98, 22), (0, -48)

Slope m = y2-y1/x2-x1

m = -48 - 22/0 -(-98)

m = -70/98

m = -35/49

Substitute m = -35/49 and (0, -48) into the equation y = mx+c

-48 = 0(-35/49) + c

-48 = c

c = -48

Hence the y-intercept is -48

Get the equation

Recall that y = mx+c

y = -35/49 x - 48

Answer:

n^2(radical)7

Step-by-step explanation:

You have to find the square root of all the components separately. 7 is not a perfect square (one number*itself = perfect square, ex 4 is the perfect square of 2 because 2*2=4) but the n^4 can be simplified and brought outside of the radical. When finding the square root of variables with exponents they have to come out in pairs to create that "perfect square." Therefore when you move a variable, you basically divide the exponent by 2. so n^4 inside the radical becomes n^2 outside of the radical, leaving the problem itself to become n^2 (radical) 7.
