Answer:

(D) $3x+2 < -7$ or $3x+2 >7$

Step-by-step explanation:

Given the absolute inequality: $|3x+2| >7$

When solving absolute inequalities, if the problem has a greater than sign we set up an "OR" compound inequality that looks like this:

(Expression inside absolute value) < - (number on other side) OR
(Expression inside absolute value) > (number on other side)

Therefore, for the absolute inequality |3x+2| >7, we have:

$3x+2 < -7$ or $3x+2 >7$

The correct option is D.

For number 6, Tom's unit rate was 0.1254 per meter. Samma's unit rate 0.1299 per meter. So Samma had a faster unit rate by 0.0045.

For number 8:
$10.45 ÷ 5 = $2.90
So the unit rate is $2.90.

Hope this helps. :)

Answer:

No, because it fails the vertical line test ⇒ B

Step-by-step explanation:

To check if the graph represents a function or not, use the vertical line test

Vertical line test: Draw a vertical line to cuts the graph in different positions,

if the line cuts the graph at just one point in all positions, then the graph represents a function

if the line cuts the graph at more than one point in any position, then the graph does not represent a function

In the given figure

→ Draw vertical line passes through points 2, 6, 7 to cuts the graph

∵ The vertical line at x = 2 cuts the graph at two points

∵ The vertical line at x = 6 cuts the graph at two points

∵ The vertical line at x = 7 cuts the graph at one point

→ That means the vertical line cuts the graph at more than 1 point

in some positions

∴ The graph does not represent a function because it fails the vertical

line test
