Answer:

-4/3

Step-by-step explanation:

Answer:

m = - 4 /3

Step-by-step explanation:

Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:

m = y2 - y1 / x2 - x1

m =( -6) - (-2)/ 5 - 2

m = -6 plus 2 / 3               I put plus because negative times negative is plus

m = -4 / 3        negative 6 plus 2 is -4

To find y2, y1, x2 and x1 you have look on the two points that they gave you.

(2, -2), The x1 is 2 and y1 is -2

(5,-6), The x2 is 5 and y2 is -6

Answer:

The answer is C.-216

Step-by-step explanation:

Answer:

C.)-216

Step-by-step explanation:

Since -6 is negative, it makes it become a positive when multiplyed, and then back to a negative when multiplyed again.

Answer:

the answer is B!! hopefully this helps

Answer:

It is rational because the answer is -3

Step-by-step explanation:

-3 can be writen as a fraction so it is a rational number.

Answer:

That is a rational number

Step-by-step explanation:

[tex]\sqrt{9}[/tex] = 3.

Therefore, -[tex]\sqrt{9}[/tex] = -1(3) = -3.

-3 is RATIONAL.  

Answer:

The letter E

false because the mountain was created with the North not the South plate.

You didn't give an original equation, just the two points so I'm just going to go ahead and assume that b = 0, but in reality, it doesn't really matter what it equals I think.

Slope intercept form:

First, we find the slope, so we do y1-y2/x1-x2 which is 3. So then we do y=mx+b so 4=3(2)+b. Then we do 4=6+b. So, b = -2.

So the equation is y=3x-2

Find the slope which we already know. Plug into y-y1=m(x-x1).

y-4=3(x-2)

y-4=3x+6

Answer:

543

Step-by-step explanation:

4(138)-9

552-9

543

Answer:

543

Step-by-step explanation:

based on PEMDAS

paranthesis first 60+78= 138

then you would multiply 4x138=552

then you would 552-9= 543

Answer:

x=1

Step-by-step explanation:

Answer:

The volume, in cubic feet, of the larger rectangular prism is 64 cubic feet

Step-by-step explanation:

Length of small cube =[tex]\frac{1}{2} ft[/tex]

Volume of each cube = Side^3

Volume of each cube =[tex](\frac{1}{2})^3[/tex]

                                    =[tex]\frac{1}{8} ft^3[/tex]

Volume of 64 cubes = [tex]64 \times \frac{1}{8}[/tex]

Volume of 64 cubes [tex]= 8 ft^3[/tex]

We are given that He uses all the cubes to fill a box shaped like a larger rectangular prism.

So, Volume of 64 cubes = Volume of rectangular prism

So, If there are 64 of these cubes in the larger prism, then the volume, in cubic feet, of the larger rectangular prism is 64 cubic feet

Answer:

55,89

Step-by-step explanation:

Here we see a sequence where the pattern is achieved by adding each new term to the term before to get the next term

5+1=6

1+6=7

6+7=13 etc

So for the next two terms: 21+34=55

55+34=89

Answer:

5, 1, 6, 7, 13, 21, 34, 51, 77

Solution:

Next possible number in the given sequence I. -4,1,8 is 17

Next possible number in the given sequence II. 5,6,13 is 26

☆ The next 2 number for given series -4,5,1,6,8,13 are 17,26

☆The next 2 number for given series 5,1,6,7,13,21,34 are 51,77

Answer:

Wala akong pake kasi ndi naman ako marunong sa math

Answer:

C. Brian and Damien both answered 2 more questions correctly than Chris did.

Step-by-step explanation:

A. Brian and Damien both answered 2 fewer questions correctly than Chris did.

B. Brian and Damien both answered 4 more questions correctly than Chris did.

C. Brian and Damien both answered 2 more questions correctly than Chris did.

D. Brian and Damien both answered 4 fewer questions correctly than Chris did.

Let

B = number of questions Brian got right

C = number of questions Chris got right

D = number of questions Damien got right

The number of questions Brian got right is 14 more than 1/4 the number of questions Chris got right.

B = 14 + (1/4) * C

Damien correctly answered 2 less than 5/4 the number of questions Chris answered correctly.

D = (5/4) C - 2

If Brian and Damien have the same score,

14 + (1/4) * C = (5/4) C - 2

14 + 1/4C = 5/4C - 2

14 + 2 = 5/4C - 1/4C

16 = 5C-C/4

16 = 4/4C

C = 16

B = 14 + (1/4) * C

= 14 + 1/4*16

= 14 + 4

= 18

D = (5/4) C - 2

= 5/4*16 - 2

= 5*4 - 2

= 20 - 2

= 18

Answer:

108

Step-by-step explanation:

base times hight i think its been a while since i looked at the area of a triangle

Answer:

The area is 54 units^2

Step-by-step explanation:

The area equation of a triangle is (base x height)/2

So I plugged in the numbers into the equation

(6 x 18 ) / 2

(108)/2

54 units^2

m = -9/8 (slope)

This means 9 down, and 8 right.

_________________________

To calculate the slope, just use this formula:

[tex] m \: = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

y2 or x2 can also be thought of as just y and x. This is because only a slope, and one point is needed to solve for another point that fits on the line.

Given point 1 : (-2,6), and point 2 : (6,-3).

We can find slope by: point 2y - point 1y/ point 2x - point 1x =

(-3-6)/(6-(-2)) = (-9)/(8) = -9/8
