what is the slope of a line b perpendicular to line a with equation y=7x-9

Answers

Answer:

The slope of line b would be -1/7.

Step-by-step explanation:

This happens because if you have the slope of any line and are trying to find the perpendicular line to said line, the slope of the perpendicular line will always be the opposite reciprocal of the original slope.

Then, all you need to do is find some points and graph the lines.

1. v= 0.013m/s

t = 60 seconds

d = v×t

= 0.013×60

|8w+5|=21
please show work

Answers

Answer:

w=-13/4

w=2

Step-by-step explanation:

|8w+5|=21

Step by step solution :

STEP

1

:

Rearrange this Absolute Value Equation

Absolute value equalitiy entered

     |8w+5| = 21

STEP

2

:

Clear the Absolute Value Bars

Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.

The Absolute Value term is |8w+5|

For the Negative case we'll use -(8w+5)

For the Positive case we'll use (8w+5)

STEP

3

:

Solve the Negative Case

     -(8w+5) = 21

    Multiply

     -8w-5 = 21

    Rearrange and Add up

     -8w = 26

    Divide both sides by 8

     -w = (13/4)

    Multiply both sides by (-1)

     w = -(13/4)

    Which is the solution for the Negative Case

STEP

4

:

Solve the Positive Case

     (8w+5) = 21

    Rearrange and Add up

     8w = 16

    Divide both sides by 8

     w = 2

    Which is the solution for the Positive Case

STEP

5

:

Wrap up the solution

w=-13/4

w=2

In the year 2015 Emily was three times as old asKaitlin. By the year 2021 Kaitlin will be half asold as Emily will be. How old was Emily on theyear 2000?

Answers

In 2000 Emily was 9 years old.

Given that in the year 2015 Emily was three times as old as Kaitlin while by the year 2021 Kaitlin will be half as old as Emily will be, to determine how old was Emily on the year 2000 the following calculation must be performed:

2015 = E = 3K 2021 = E = 2K  24 /// 8 --- 30 /// 14 18 /// 6 --- 24 /// 12 18/6 = 3 24/12 = 2 2015 = Emily was 24 years old 24 - (2015 - 2000) = X 24 - 15 = X 9 = X

Therefore, in 2000 Emily was 9 years old.

P = 2W + 2L

26 = 2(x) + 2(x + 3)

26 = 4x + 6

26 - 6 = 4x

20 = 4x

Is the following a function?
{(1, -2), (-2, 0), (-1, 2), (1,3)}

Answers

it is not a function. A function is a relation in which no two ordered pairs have the same input (or x-values) and different outputs (y-values).

You need to determine whether every first element (or input) correspond with EXACTLY ONE second element (or output).

in this case, the input value of 1 goes with two output values, -2 and 3.  

It only takes one input value to associate with more than one output value to be invalid as a function.

Therefore, the given relation is not a function.
