Answer:
5/3
Step-by-step explanation:
2x+3=5x-2
Subtract 2x from both sides
3=3x-2
Add 2
5=3x
Divide by three
5/3=x
Answer:
<h2>a.) reflect across x-axis</h2>
Step-by-step explanation:
The transformation described is about multiplying the vertical value by -1:
That means all vertical coordinates will change to the opposite side, but all horizontal coordinates will maintain at the same coordinate.
As a result, we'll have a reflection across the x-axis, because the y coordinates were transformed.
Therefore, the right answer is A.
Answer:
Step-by-step explanation:
The owner of the store has determined that home delivery will be successful if the average time spent on the deliveries does not exceed 34 minutes. This is the null hypothesis. It is written as
H0 : µ ≤ 34
The alternative hypothesis would be
Ha : µ > 34
This is a right tailed test because of the greater then symbol in the alternative hypothesis. Since the p value for the test was found to be 0.0281281, if we use a significant level of 0.05, then the conclusion would be
Reject the null hypothesis. Therefore, At a 5% level of significance, the sample data showed significant evidence that the average time spent on the deliveries does exceed 34 minutes.
Answer:
Yes
Step-by-step explanation:
To be a function, the graph must pass the vertical line test.
The vertical line test is simple. Imagine you draw an infinite number of vertical lines. In all of these lines, it should never hit the function twice in the same x value.
For example, if it hits (4, 2) and (4, 7), the graph is not a function because there are two points with the same x value.
Basically that’s it but write it down by yourself
