Answer:

$x \geq -91/2$

Step-by-step explanation:

$6(x+8) \geq -43 + 4x$

Resolving Parenthesis

$6x+48 \geq -43 + 4x$

Collecting like terms

$6x - 4 x \geq -43-48$

$2x \geq -91$

Dividing both sides by 2

$x \geq -91/2$

Find an equation of the line having the given slope and containing the given point.

arlik [135]

Answer:

$y = -6x + 39$

Step-by-step explanation:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept(value of x when y = 0).

We have that the slope is m = -6:

So $y = -6x + b$

Contains point (5,9):

This means that when $x = 5, y = 9$ . We replace this into the equation to find b. So

$y = -6x + b$

$9 = -6(5) + b$

$b = 39$

$y = -6x + 39$
