Question

Graph the solution to the following linear inequality in the coordinate plane.

Answer 1

Answer:

$A. \ h(x)=6x+13$

Step-by-step explanation:

The total number of students selected from both universities can be found as:

$f(x)+g(x)$

Where:

• $f(x)$ represents the number of students selected from university A
• $g(x)$ represents the number of students selected from university B
• $x$ represents the number of days of the fair.

So:

$h(x)=f(x)+g(x) \\ \\ h(x)=(4x+5)+(2x+8)$ grouping terms:

$h(x)=(4x+2x)+(8+5) \\ \\ Solving: \\ \\ h(x)=6x+13$

The graph of the function is shown below and you can realize that the solution is a linear equation.
