Answer:
Table 20.
Step-by-step explanation:
Find the LCM of 4 and 5,
4, 8, 12, 16, 20
5, 10, 15, 20, 25
20 is the LCM of 4 and 5.
Hence giving 20 as the answer.
Answer:
<h2>See the explanation and the image.</h2>
Step-by-step explanation:
The inequality
means
.
y = 0, satisfies the above inequality, so the arrows will be towards the x axis.
Now, we need to draw 5x < 8 + 4y.
First, lets draw the equation of 5x = 8 + 4y.
y = 1 gives x = 2.4 & y = 0 gives x = 1.6.
Hence, the above equation passes through (2.4, 1) and (1.6, 0).
The point (0, 0) satisfies the inequality 5x < 8 + 4y. Hence, the arrows will be towards the origin.
The solution will be the area of APQ except any point on PQ, as PQ is nothing but the line 5x = 8 + 4y.
Using linear functions, she pays the same for 10 classes, which is represented by the graph at the end of the question.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For this problem, we consider the flat fee as the intercept and the cost per group class as the slope, hence the functions are given by:
She pays the same when:
A(x) = B(x).
70 + 3x = 40 + 6x
3x = 30
x = 10.
Hence when there are 10 classes.
