Answer:

\huge  \frac{7}{8}  \\

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

m =  \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\

From the question we have

m =  \frac{ - 9 -  - 2}{ - 10 -  - 2}  =  \frac{ - 9 + 2}{ - 10 + 2}  =  \frac{ - 7}{ - 8}  =  \frac{7}{8}  \\

We have the final answer as

\frac{7}{8}  \\

Hope this helps you

Solve and check x+6=2x-7
ira [324]

x = 13

subtract x from both sides of the equation

6 = 2x - x - 7

6 = x - 7

add 7 to both sides

6 + 7 = x ⇒ x = 13

As a check

substitute this value into the equation and if both sides are equal then it is the solution

left side = 13 + 6 = 19

right side = (2 × 13) - 7 = 26 - 7 = 19

hence x = 13 is the solution

Ellason wants to solve the following system using the elimination method: 5x + 2y = 30 x + y = 8 What number should the equation
Zinaida [17]
 - 2 because we obtain : - 2x - 2y = - 16 ;
We solve the system:
5x + 2y = 30
-2x - 2y = -16
_____________(+)
3x /       = 14;
x = 14/3;
y = 8 - 14/3;
y = 24/3 -14/3;
y = 10/3;

The solution of the system is ( 14/3 ; 10/3 )

Complete question :

Compute the probability of each of the following events.

Event : The sum is greater than 6

Event : The sum is not divisible by 2

Answer:

7/12 ; 1/2

Step-by-step explanation:

Sample space :

2, 3, 4, 5, 6, 7

3, 4, 5, 6, 7, 8

4, 5, 6, 7, 8, 9

5, 6, 7, 8, 9, 10

6, 7, 8, 9, 10, 11

7, 8, 9, 10, 11, 12

Probability that sum is greater than 6:

Number of outcomes greater Than 6 = required outcomes = (7,7,7,7,7,7,8,8,8,8,8,9,9,9,9,10,10,10,11,11,12) = 21

Total sample space = total possible outcomes = 36

Probability = required outcome / Total possible outcomes

P(sum is greater Than 6) = 21 / 36

2.)

Obtaining an even number :

Sum not divisible by 2 = required outcomes = (3, 5, 7, 3, 5, 7, 5, 7, 9, 5, 7, 9, 7, 9, 11, 7, 9, 11) = 18

Total sample space = total possible outcomes = 36

P(sum is not divisible by 2) = 18 / 36 = 1 / 2
