Answer:G
Explination:
Marianne is incorrect because like terms are terms that have the same variables, raised to the same powers. The terms –x and 2x fit the definition for like terms. The term –x has a coefficient of –1. Marianne is not correct
Answer:
The constant of proportionality is 15.
Step-by-step explanation:
The constant of proportionality is the number at wich the two variables relate. In this case for every second running the wolf will travel a distance of 15 m, this means that if two seconds have passed the wolf will have travelled a distance of 30m and so on. So we can assume that the constant for this question is 15.
Answer:
5/3
Step-by-step explanation:
Divide both sides by 0.75:
12x - 4 = 16
12x = 20
x = 20/12 = 5/3
Answer:
x=9
Step-by-step explanation:
Given:
The graph of a function.
To find:
The intervals where the function is increasing and decreasing.
Solution:
A function is increasing if the function increases as the value of x increases.
A function is decreasing if the function decreases as the value of x increases.
From the given graph it is clear that the graph is decreasing for , then the graph increasing for after that the function again start decreasing for .
Function Increasing over:
Function decreasing over: .
Therefore, the function is increasing over the interval and the function is decreasing over the interval .
