Answer: First Option
The slope is −0.4. Starting at 3.8, the GPA will decrease by 0.4 for every text sent in class.
Step-by-step explanation:
The equation of a line has the following form
Where m is the slope of the line and b is the intercept with the axis of the y
In this case, the equation is:
Observe that
So if x represents the number of texts sent during classes, this means that
When x increases by one unit then y decreases -0.4. For example when then
Then the greatest value it can take the GPA is 3.8. Therefore we can say that the function starts at y = 3.8.
The answer is the first option
20/100 could be converted to 2/10 or 1/5
2/8 could be converted to 1/4
90/100 could be converted to 9/10
Answer:
The value of r is 0.451
The percentage decrease is about 45.1%
Step-by-step explanation:
The given exponential function is
Using the exponent rule,
Now the value of
Thus, we can rewrite the function as
Therefore, the function in form
The value of r is 0.451
The percentage decrease is about 0.451 ×100 = 45.1%
