Answer:
-3 ≤ x ≤ 19/3
Step-by-step explanation:
This inequality can be resolved to a compound inequality:
-7 ≤ (3x -5)/2 ≤ 7
Multiply all parts by 2.
-14 ≤ 3x -5 ≤ 14
Add 5 to all parts.
-9 ≤ 3x ≤ 19
Divide all parts by 3.
-3 ≤ x ≤ 19/3

<em>Additional comment</em>
If you subtract 7 from both sides of the given inequality, it becomes ...
|(3x -5)/2| -7 ≤ 0
Then you're looking for the values of x that bound the region where the graph is below the x-axis. Those are shown in the attachment. For graphing purposes, I find this comparison to zero works well.

For an algebraic solution, I like the compound inequality method shown above. That only works well when the inequality is of the form ...
|f(x)| < (some number) . . . . or ≤
If the inequality symbol points away from the absolute value expression, or if the (some number) expression involves the variable, then it is probably better to write the inequality in two parts with appropriate domain specifications:
|f(x)| > g(x) ⇒ f(x) > g(x) for f(x) > 0; or -f(x) > g(x) for f(x) < 0
Any solutions to these inequalities must respect their domains.

Answer:
It's A.
Step-by-step explanation:
5x2 + 60x = 0
5x is the GCF so:
5x(x + 12 ) = 0
5x = 0, x + 12 = 0
x =0, x = -12.
The additional set of values which could be included in the table is; (10,2).
<h3>Which additional set of values can be included in the table?</h3>
As evident in the task content, it follows that for a 15 unit increase in x, depth, there is a 3 unit increase in y, pressure.
On this note, it follows that with each 5 unit increase in x corresponds to 1 unit increase in y.
And ultimately, at x = 10, y = 2 × 1 = 2.
