Explanation:
This is a self-answering question: you solve it by graphing the equations.
<em>The solution is where the lines intersect</em>. The point of intersection of the lines is the point that satisfies all the equations for the lines, hence is a solution to the system. If they do not intersect, there are no solutions. If the lines are coincident, there are an infinite number of solutions.
__
The equations can be graphed by any of a number of methods. (My favorite is to let a graphing calculator do it.) The method of choice depends on the coefficients and the form the equations are given in. Methods of graphing are a topic for a more lengthy discussion.
Answer:
2 rides per hour
Step-by-step explanation:
This is a division problem since we would need to divide in order to answer the question.
Divide the amount of rides she rode to the number of hours she was there.
Input the numbers below:
amount of rides she rode/number of hours there
14/7=2
At this rate, Ramona rode 2 rides per hour.
Answer:
The answer for number one is $5.21. NOT $6.25
Step-by-step explanation:
Answer:
The population of the students at the University after 5 years is <u>442</u>.
Step-by-step explanation:
Given:
Current population of students is, 
Growth rate is, 
Time after which population is needed is, 
Let 'P' be the population after 't' years.
Population growth is an exponential growth and the equation to determine the population after 't' years is given as:
Now, plug in 400 for 
, 0.02 for 'r', 5 for 't' and solve for 'P'. This gives,
Therefore, the population of the students at the University after 5 years is 442.
