Find the coordinates of H if X(-8, 4) is the midpoint of GH and G(2, -9).

skelet666 [1.2K]

Step-by-step explanation:

Hey there!

The given midpoint is; X(-8,4) and G(2,-9).

To find: H

Now; You need to use formula for midpoint.

$midpoint(x) = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )$

Put all values.

$( - 8,4) = (\frac{ 2 + x}{2} , \frac{ - 9 + y}{2} )$

As they are equal, their corresponding elements are equal.

$- 8 = \frac{2 + x}{2}$

$- 16 - 2 = x$

x = -18

$4 = \frac{ - 9 + y}{2}$

$4 \times 2 = - 9 + y$

$8 + 9 = y$

$y = 17$

Therefore, y = 17.

Therefore, H =( -18,17).

Hope it helps....

Multiply the following binomials. (4x-6)(x-7)

Alexxandr [17]

Answer:

4x^2 -34x+42

Step-by-step explanation:

(4x-6)(x-7)

FOIL

first 4x*x = 4x^2

outer 4x*-7 = -28x

inner : -6 *x = -6x

last : -7*-6 = 42

Add them together = 4x^2 -28x-6x +42

=4x^2 -34x+42

A line passes through the points (2,-4) and (6,10). What is the equation of the line?

deff fn [24]

Answer:

y = $\frac{7}{2}$ x - 11

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (2, - 4) and (x₂, y₂ ) = (6, 10)

m = $\frac{10+4}{6-2}$ = $\frac{14}{4}$ = $\frac{7}{2}$ , thus

y = $\frac{7}{2}$ x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (2, - 4) , then

- 4 = 7 + c ⇒ c = - 4 - 7 = - 11

y = $\frac{7}{2}$ x - 11 ← equation of line
