Answer:

The required solution for x is $x=-\frac{4}{k}$

Step-by-step explanation:

Given : Equation $kx+8=4$

To find : Solve the given equation for x?

Solution :

Step 1- Write the equation,

$kx+8=4$

Step 2 - Subtract 8 both side,

$kx+8-8=4-8$

$kx=-4$

Step 3- divide both side by k,

$\frac{kx}{k}=\frac{-4}{k}$

$x=-\frac{4}{k}$

Therefore, The required solution for x is $x=-\frac{4}{k}$

SOMEOME HELP this is my third time posting those SERIOUSLY HELP ME PLEASE

The correct answer is C (7, 9)

Firstly we know that each point is 6 away from the other in terms of x and in terms of y. Now we also know that for every 6, we will be one away from point B and five away from point A. We know this because the ratio is AB 5:1, meaning that the 5 is on the A side (they both come first).

So, we can just add 5 to each of the A value numbers to get point P.

A = (2, 4)

P = (2+5, 4+5)

P = (7, 9)

The coordinates of the vertices of the triangle are
(–8, 8), (–8, –4), and (10, –4).

Consider QR the base of the triangle. The measure of the base is b = 18 units, and the measure of the height is h = 12 units.

The area of triangle PQR is108 square units.
