Answer:
b. <u>x + 4</u>
Solution:
Student's age = x
Teacher's age = 6 + 2x
Principal's age = 10 + 3x
Difference in the age of the teacher and principal
(10 + 3x) - (6 + 2x)
= 10 + 3x - 6 - 2x
= (10 - 6) + (3x - 2x)
= 4 + x
Answer:
2.4 hours
Step-by-step explanation:
The graph is a straight line graph. A straight line graph is used to represent a linear equation. A linear equation is represented by the equation: y = mx + c, where y is the dependent variable, x is the independent variable, m is the slope (rate of change) and c is the intercept.
A line passing through the point can be represented by the equation:
Let y represent the distance in miles and x represent the time in hours. From the graph, the line pass through (0.5, 100) and (3.5, 700). Hence using:
