Answer:
Neither
Step-by-step explanation:
To verify, we substitute the values in the equations:
however, the value should be 4. Hence this equation does not satisfy the co-ordinate.
however, the value should be 4. Hence this equation does not satisfy the co-ordinate.
Given the System of Equations:
The exercise asks for solving it graphically. Then, in this case, you need to graph both lines in order to determine the solution of the system.
In order to graph it, you can find the x-intercepts and the y-intercepts:
1. It is important to remember the Slope-Intercept Form of the equation of a line:
Where "m" is the slope of the line and "b" is the intercept.
In this case, you can identify that the y-intercept of the first line is:
And the y-intercept of the second line is:
2. By definition, the value of "y" is zero when the line intersects the x-axis.
Then, you need to substitute the following value of "y" into each equation and then solve for "x", in order to find the x-intercept of each line:
- For the first line, you get:
- For the second line, you get:
3. Now you know that the first line passes through these two points:
And the second line passes through these two points:
4. Knowing those points, you can graph the lines:
Notice that the line intersect each other at
<u>Answer:</u>
Below!
<u>Step-by step explanation:</u>
<u>We know that:</u>
<u>Solution of Question A:</u>
<u>Percent of children: Total children/Total attendance</u>
<u>Hence, the percent of children is about 27%.</u>
<u>Solution of Question B:</u>
<u>Percent of women: Total women/Total attendance</u>
<u>Hence, the percent of women is 56.67%.</u>
<u>Solution of Question C:</u>
<u>Percent of men: Total men/Total attendance</u>
<u>Hence, the percent of men is about 17%</u>
Hoped this helped.
