Answer:

y - 8 = (-1/27)(x + 3)

Step-by-step explanation:

the slope of a line perpendicular to the given y = 27x + 117 is the negative reciprocal of 27, that is, -1/27.  Using the point-slope form  y - k =m(x - h)  to write the new equation, we get:

y - 8 = (-1/27)(x + 3)

Answer:

3

Step-by-step explanation:

When multiplying and dividing with negative numbers, use this key to help:

( - ) x ( + ) = ( - )

( + ) x ( + ) = ( + )

( - ) x ( - ) = ( + )

For example, with your problem, Both numbers are negative, meaning that the end result will be positive. -3 x -1 = 3

Answer:

step 1. y - y1 = m(x - x1). This is the standard line equation given a point and a slope.

step 2. parallel lines have the same slope so the slope is -4.

step 3. y - (-5) = -4(x - (-4)).

step 4. y + 5 = -4x - 16.

step 5. y = -4x - 21.

Answer:

between 17 and 18

Step-by-step explanation:

x² = 315

To find the range that the value is in, you need to know the perfect squares before and after 315.

17² = 289

18² = 324

289 < 315 < 324

This means √315 is between 17 and 18.

Answer:

60 degrees counterclockwise

Step-by-step explanation:

One circle is 360 degrees.

If the circle is split into 6 pieces, (360/6 = 60), then each piece is 60 degrees, like in the example.

Answer:

60 degrees counterclockwise

Step-by-step explanation:

Answer:

There are no options, so i will answer in a general way.

In a function:

y = f(x)

The output is y, and the input is x, and the ordered pair is written as (x, y)

In this case, we have the function:

y = -7*x + 6

Then we need to have different inputs and then find the outputs for each.

For example, if x = 1.

y = -7*1 + 6 = -1

Then we have the ordered pair (1, - 1)

if x = 0

y = -7*0 + 6 = 6

then we have the ordered pair (0, 6)

The general ordered pair is written as:

(x, y =  -7*x + 6)

or:

(x,   -7*x + 6)

Where you only need to replace the value of x.

Answer: 50 or 25

Step-by-step explanation:

i apologize if i am wrong

I would say it would be 55 and if this question.If you get the answer incorrect my apologies

Step-by-step explanation:

40 + y + y + 30 = 180

2y + 70 = 180

2y + 70 (-70) = 180 (-70)

2y = 180 - 70

2y = 1102y/2 = 110/2

y = 110/2

y = 55

Answer:

Step-by-step explanation:

f(x) = -3x-6

slope of line is -3

parallel lines have the same slope

point-slope equation for line of slope -3 that passes through (6,-8):

y+8 = -3(x-6)

put equation into slope-intercept form:

y = -3x + 10

Answer:

[tex]y = - 3x + 10[/tex]

Step-by-step explanation:

We are asked to find a line parallel to line f

[tex] - 3x - 6[/tex]

and passes through 6,-8.

Parallel lines have the same slope so our new line will also has-3 as it slope

wo using the slope intercept form let update our equation so far.

Slope intercept is

[tex]y = mx + b[/tex]

where m is the slope and b is the y intercept

plug in -3 for the slope since our new equation must be parallel.

[tex]y = - 3x + b[/tex]

Now plug 6 for x and -8 for y.

[tex] - 8 = - 3(6) + b[/tex]

[tex] - 8 = - 18 + b[/tex]

[tex]b = 10[/tex]

Our equation is

[tex]y = - 3x + 10[/tex]

Answer:

-2   :)

Step-by-step explanation:

Answer:

The value of x must be 6. Because as it is said that the longest side of this shape is 12 therefore, if 2 is multiplied with 6 one of tge sides is 12, which is the biggest.
