<h3>Answer: x = 1</h3>
=====================================
Explanation:
- Step 1) Start at -1 on the y axis.
- Step 2) Draw a horizontal line from -1 until you reach the g(x) curve.
- Step 3) Mark the point of intersection. Let's call it point A.
- Step 4) From point A, draw a vertical line until you reach the x axis. You should get to x = 1.
All of this is shown in the diagram below.
Now follow the arrows in reverse. This shows that x = 1 leads to y = g(x) = -1.
Therefore, g(1) = -1 and x = 1 is the solution to g(x) = -1.
Side note: The equation is g(x) = 2x-3. We can replace g(x) with -1 and solve for x to get x = 1.
Using the percentage concept, it is found that 60% of the students voted to donate a telescope.
<h3>What is a percentage?</h3>The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
In this problem:
- The total amount is the number of students, which is of b = 500.
- 300 voted to donate, hence a = 300.
The <em>percentage </em>is given by:
60% of the students voted to donate a telescope.
