Answer:
Linear Proportional Relationship
General Formulas and Concepts:
<u>Algebra I</u>
- Linear - Any degree of 1 in the form of y = mx + b or Ax + By = C
- Nonlinear - Any degree higher than 1
Step-by-step explanation:
<u>Step 1: Define</u>
y = 2x + 3
<u>Step 2: Identify</u>
We see we have a linear equation in y = mx + b. We can also see that it is a degree of 1. Therefore, it is a Linear proportional relationship.
Answer:
11.00 pm
Step-by-step explanation:
Given that at 11:00 AM a bus left San Jose travelling to Los Angeles at 48 mph. Hence in 4 hours it would have travelled
48x4 = 192 miles
When the bus travelled 192 miles a motorcyclist started in the same direction with speed 72 mph
Difference in speed per hour = 72-48 = 24 mph
TO cover the distance of 72 miles, time taken for the motorcycist would be
192/24 = 8 hours
In 8 hours or at 11.00 p.m. motorcycle will catch upto the bus,
Work in rates per hour. These rates can then be added to form an equation
1/13 + 1/10 = 1/x where x is the time for both working together
multiply thru by 130x:-
10 x+ 13 x = 130
x = 130/23 = 5.65 hours or about 6 hours 39 minutes
Answer:
2,160
Step-by-step explanation:
432-324=108 earnings based on sales
sales x 5%=108
