Answer: Choice C</h3>
{x | x < -12 or x > -6}
=========================================================
Explanation:
Let's solve the first inequality for x.
(-2/3)x > 8
-2x > 8*3
-2x > 24
x < 24/(-2)
x < -12
The inequality sign flips when we divide both sides by a negative value.
Let's do the same for the second inequality.
(-2/3)x < 4
-2x < 4*3
-2x < 12
x > 12/(-2)
x > -6
The conclusion of each section is that x < -12 or x > -6 which points us to <u>choice C</u> as the final answer.
Side note: The intervals x < -12 and x > -6 do not overlap in any way. There's a gap between the two pieces. We consider these intervals to be disjoint. The number line graph is below.
Answer:
a relationship ( model equation)
Step-by-step explanation:
the relationship specifies how the dependent variable relies on the independent variable.This helps in manipulating of the variable to see its effect/outcome.The relationship can be mathematical or logical ; it can also be a set of algorithm (program) which can be worked on using the independent variables as inputs. Usually the independent variables influence the dependent variables.
Answer: 5
Step-by-step explanation: When there is more than one term inside the absolute value, we first simplify inside the absolute value.
So here, our first step is to add -15 + 10 which is -5.
So we have ║-5║.
Now remember that absolute value means <em>distance from zero</em> on a number line. Since -5 is 5 units from zero, the absolute value of -5 is 5.
So the absolute value of -15 + 10 is 5.
