Answer:

y = -3x -2 ( this is only for 5 )  

Step-by-step explanation:

Step 1:

First, we need to understand that lines that are perpendicular have slopes that are opposites and reciprocals of each other.

Step 2:

So our initial equation is 2x-6y= 10. We want to rearrange this so that it is in slope-intercept form: y= 1/3x -(10/6). In this form, we can derive the slope of our new line. Because the slope is 1/3, our new slope is -3 ( based on step 1 ).

Step 3:

Now that we have the slope of our new line, we can use the point-slope formula to get our specific line that passes through ( 2, -8 ).

y - y1 = m( x - x1 )

y- ( -8 ) = -3( x - 2 )jhvjjfjhjfhcgch

y + 8 = -3x + 6

y = -3x -2 !

Answer:

f^-1 (x)= x/18 - 7/54

Step-by-step explanation:

The inverse function of h(x) is x/18 - 7/54

The inverse function is defined as a function obtained by reversing the given function.

Given function h(x) = 18x+7/3

Let g(x) function is the inverse function of h(x)

Suppose y = h(x)

y = 18x+7/3  

y-7/3 = 18x

y/18 - 7/54 = x

g(x) = x/18 - 7/54

Hence g(x) = x/18 - 7/54 is the inverse function of h(x)

Answer:

Step-by-step explanation:

1) Order the numbers using the data from 2001-2004

70,60,81,19

2) Add them all together

70+60+81+19= 230

3) Divide the answer you got by the amount of numbers there are

70,60,81,19=4 numbers

230/4 = 57.5

4) Therefore the average rate of change between 2001-2004 is 58 employees (since you can't have a fraction of a person you would have to round)

Answer:

C. x = 150

Step-by-step explanation:

This shape has 6 sides and vertices which represents a hexagon. A hexagon has a total of 720°.

We can make an equation and solve for x.

90 + 120 + 112 + 118 + x + 130 = 720

570 + x = 720

x = 150

Answer:

x=16

Step-by-step explanation:

3 times 16 equals 48 minus 9 equals 39

Answer:

16

Step-by-step explanation:

To solve the equation you must isolate the variable.

3x-9=39

So first, add 9 to both sides

3x-9+9=39+9

3x=48

Then divide both sides by 3

3x/3=48/3

x=16

Answer:

Answer:

x= 1

Step-by-step explanation:

y= -2 + 1

3x - 2y = 5

substituting method:

substituting y= -2+1 in equ. 3x-2y=5

=> 3x - 2(-2 + 1) = 5

=> 3x +4 -2 = 5

=> 3x + 2 = 5

=> 3x = 5 -2

=> 3x = 3

=> x = 3/3

=> x = 1

Answer:

69°+72°=141°

180°-111°=69°

y=69°

Answer:because 2 can’t go into 9 and 8 can’t go into 3

Step-by-step explanation

-

The ratio shows how many times one value is contained in another value.

3/2 ≠ 9/8

The ratios are not the same in their simplest form so 3:2 and 9:8 are not equivalent ratios

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

3:2 and 9:8

We will simplify it in its simplest form.

3:2 = 3/2

This is the simplest form.

9:8 = 9/8

This is in its simplest form.

So,

3/2 is not equal with 9/8

If the two ratios are the same we can call them equivalent ratios.

Thus,

3/2 ≠ 9/8

The ratios are not the same in their simplest form so 3:2 and 9:8 are not equivalent ratios.
