The solution for the compound inequality is $x \in(2,6)$

Explanation:

The equations are $3.5x-10>-3$ and $8x-9$

To find the solution set for these compound inequalities, we need to solve the inequality.

First, we shall solve the inequality $3.5x-10>-3$

Adding both sides of the equation by 10, we have,

$3.5x>7$

Dividing both sides by 3.5, we get,

$x>2$

Now, we shall solve the inequality $8x-9$ ,

Adding both sides of the equation by 9, we have,

$8x$

Dividing both sides by 8, we get,

$x$

Thus, the solution set for the inequalities $3.5x-10>-3$ and $8x-9$ is $x \in(2,6)$

Answer:

No, to be a function a relation must fulfill two requirements: existence and unicity.

Step-by-step explanation:

Existence is a condition that establish that every element of te domain set must be related with some element in the range. Example: if the domain of the function is formed by the elements (1,2,3), and the range is formed by the elements (10,11), the condition is not respected if the element "3" for example, is not linked with 10 or 11 (the two elements of the range set).
Unicity is a condition that establish that each element of the domain of a relation must be related with <u>only one</u> element of the range. Following the previous example, if the element "1" of the domain can be linked to both the elements of the range (10,11), the relation is not a function.
