Answer:

  -1

Step-by-step explanation:

The slope of a line between two points is given by the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (7 -(-3))/(-2 -8) = 10/-10

  m = -1

The slope of the line is -1.

The sum of two numbers is 19, and their difference is 55. What are the two numbers?
Vilka [71]

Answer:

37 and -18

Step-by-step explanation:

Let one number be x and other y

1 x + 1 y = 19 .............1

1 x -1 y = 55 .............2

Eliminate y

multiply (1)by 1

Multiply (2) by 1

1 x 1 y = 19

1 x + -1 y = 55

Add the two equations

2 x = 74

/ 2

x = 37

plug value of x in (1)

1 x + 1 y = 19

37 + 1 y = 19

1 y = 19 -37

1 y = -18

y = -18

37 and -18

MAVERICK [17]

Answer:

20

15\%x = 3

x=3\div 15\%

=20

∴ Lola's hockey team played a total of 20 games.

3, 8, 13, 18, 23, 28, 33, 38
algol [13]

The given series is

3,8,13,18,23,28,33,38,...

Where the first term, a , is 3.

And the difference is constant, that is

8-3=13-8=18-13=5

So the constant difference, d is 3.

Since the difference is constant, so the given series is arthmetic.

And for explicit rule, we use the formula of nth term, which is

a_{n}= a+(n-1)d

Substituting the values of a and d, we will get

a_{n} = 3+(n-1)5&#10;\\&#10;a_{n} = 3+5n-5&#10;\\&#10;a_{n} = 5n -2

Recursive rule is used to tell us the relationship between previous and current term. And the required rule is

a_{n} = a_{n-1} +5 , a_{1} = 3
