<h3>Answer:</h3>

y = -5x -1

<h3>Step-by-step explanation:</h3>

Changes in x-values are constant and are +1.

Changes in y-values are constant and are -5.

Because the ratio of changes in y to changes in x is constant (-5/1) = -5, you know the function is linear. To write the equation, you can use the slope-intercept form, since you know the slope (-5) and the table shows the y-intercept: (x, y) = (0, -1).

The rule is ...

... y = -5x -1

Identify the factors of the terms of the expression. 3). 5+6a+11b 4). 13m-2n

xeze [42]

Answer:

factors are 5, 6, a, 11, b

Step-by-step explanation:

3) 5 + 6a + 11b

Algebraic expressions: 5 + 6a + 11b 

Are combinations of numbers, variables, and at least one arithmetic.

Term are: 5, 6a, 11b

Each expression is made up of terms. A term can be a signed number, a variable, or a constant multiplied by a variable(s).

Factors are: 5, 6, a, 11, b

Something which is multiplied by something else. A factor can be a variable, number, a term, or a longer expression.

Coefficient: 6, 11

The numerical factor of a multiplication expression that contains a variable.

Constant: 5 

A number that cannot change its value.

4). 13m-2n (note: it applies as above)

Plz help it is a probability question it is soo hard - I have tried and tried

zalisa [80]

I think there's an easy way and a hard way to do this, and I think that the way
I'm about to describe is the easier way.

Probability = (number of successful outcomes)/(total number of possible outcomes)

How many total pairs can be drawn from 8 total pens ?
-- The first one drawn can be any one of 8 pens. For each of these . . .
-- The second one drawn can be any one of the remaining 7 .
-- Total number of ways of drawing a pair = (8 x 7) = 56 ways.
-- But there aren't 56 different different pairs. Whether you draw A and then B,
or B and then A, you wind up with the same pair. There are 2 different ways to
draw each pair, so the 56 ways of drawing a pair only produces 28 different pairs.

How many pairs are two of the same color ?

Possible number of blue pairs:
The reasoning is exactly the same as calculating the TOTAL number of
pairs, as explained above.
With 5 blue pens, you can make 10 different pairs.
AB, AC, AD, AE, BC, BD, BE, CD, CE, and DE.

Possible number of red pairs:
The reasoning is exactly the same as calculating the TOTAL number of
pairs, as explained above.
With 3 red pens, you can make 3 different pairs.
AB, AC, and BC.

Total number of possible same-color pairs = 10 + 3 = 13

successes / total possible outcomes = 13/28 = 46.4% (rounded)

Randall buys a wooden board that is 5 7/8 feet long. The cost of the wooden board is 0.25 per foot including tax. Enter the tota

AURORKA [14]

Answer:

Total Cost = $1.47

Step-by-step explanation:

Length of the wooden board = $5\frac{7}{8} =\frac{47}{8}$

Cost of the wooden board = $0.25 per foot

Total Cost = Cost per foot X Total Length in foot

= $0.25 X \frac{47}{8} =1.47$

Total Cost = $1.47
