The length of the missing side can be calculated by the following steps;
Step-by-step explanation:
Answer:
y = -2·x^2 - 5·x - 18
y = -2·(x^2 + 10·x + 36)
y = -2·(x^2 + 10·x + 36)
y = -2·(x - (-5 - √11·i))·(x - (-5 + √11·i))
Maybe there is a typo in the original question, because there is no factorisation in the real numbers.
Because the question is " find the minimum value of y" the coefficient before x^2 must be a positive number. so it could be
y = 2·x^2 - 5·x - 18

Solution: Which statement about the scatter plot is true?
The correct answer is option A. As the number of weeks in class increases, the number of keyboarding mistakes decreases.
Explanation: From the scatter plot, we clearly see there exists a negative linear relationship between the number of weeks in class and the number of mistakes. And we know that if there exists a negative linear relationship between the two variables, then the values of two variables move in opposite direction. If the values of one variable goes up, the values of other variable go down. From the given scatter plot, we clearly see the number of mistakes goes down as the number of weeks in class increases. Therefore, the option A is correct
Answer:
1 hour 37 minutes
Step-by-step explanation:
From the image attached, we can see the start and end time represented by the clock. To calculate the length of time that Maria and her friends rode, we just have to subtract the start time from the end time.
From the end time clock, we can see that the end time is 2:24, while from the start time clock, we can see that the start time is 12:47. Hence, the length of time they rode is:
Length of time for bike ride = 2:24 - 12:47 = 1 hour 37 minutes
