aliya0001 [1]

Solve this equation: $45 - ($2.75/pen)x = $12. Simplifying, we get

$33 = ($2.75)x, so that

x = $33 / ($2.75) = 12.

Tim's buying 12 pens leaves him with $12.

Solve |2x - 6| > 10

inn [45]

ANSWER

{x|x < -2 or x > 8}

EXPLANATION

The given absolute inequality is

$|2x - 6| \: > \: 10$

By the definition of absolute value,

$(2x - 6)\: > \: 10 \: or \: \: - (2x - 6)\: > \: 10$

Multiply through the second inequality by -1 and reverse the inequality sign

$2x - 6\: > \: 10 \: or \: \: 2x - 6\: < \: - 10$

$2x \: > \: 10 + 6\: or \: \: 2x \: < \: - 10 + 6$

Simplify

$2x \: > \: 16\: or \: \: 2x \: < \: -4$

Divide through by 2

$x \: > \: 8\: or \: \: x \: < \: -2$

2 Points

In-s [12.5K]

Answer:

D. -3

Step-by-step explanation:

The table is:

x | y

-5 | 23

-2 | 14

1 | 5

To find the slope, you need two points (x1, y1) and (x2, y2) and the next formula:

slope = (y2 - y1)/(x2 - x1)

Using (-2, 14) and (1, 5) (other combinations are also possible) the slope is:

slope = (5 - 14)/(1 - (-2)) = -3
