7 - 4x = 7y
1 - 4/7x = y....y = -4/7x + 1...slope here is -4/7. 
A parallel line will have the same slope

y = mx + b
slope(m) = -4/7
(2,0)...x = 2 and y = 0
now sub and find b, the y int
0 = -4/7(2) + b
0 = -8/7 + b
8/7 = b

so ur parallel equation is : y = -4/7x + 8/7 <=

The location of the mid point between (-15,4) (2,-10)
frozen [14]

Answer:

The answer is

<h2>( -  \frac{13}{2} , \:  - 3)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

<h3>M  = ( \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )</h3>

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-15,4) (2,-10)

The midpoint is

<h3>M = ( \frac{ - 15 + 2}{2}  , \:  \frac{4 - 10}{2}  ) \\  = ( -  \frac{13}{2} , \:  -  \frac{6}{2} )</h3>

We have the final answer as

<h3>( -  \frac{13}{2} , \:  - 3)</h3>

Hope this helps you

marshall27 [118]
I think the best way is to use a computer drawing program in constructing a regular hexagon inscribed in a circle. Its because a computer program is an accurate, precise and the most important it is more efficient than using the straight edge and compass

Answer:

g(x) = 5x + 2.

r(x) = x

b(x) = 1/2 x³

k(x) = - 3 x + 1

Step-by-step explanation:

The function notation ⇒ it is the form to write the function, It is meant to be a precise way of giving information about the function, like f(x) , v(x) and so on.

Given the following:

g(x) = 5x + 2.

y = 1 x

h = x²

r(x) = x

f/x = x⁵ - 3

b(x) = 1/2 x³

p/x = -7x

k(x) = - 3 x + 1

y = mx + b

fx = -x³ + 4

So, in the given options the following are in function notations:

g(x) = 5x + 2.

r(x) = x

b(x) = 1/2 x³

k(x) = - 3 x + 1
