Answer:
Step-by-step explanation:
Since it's a perfect square, we can simply use the formula:
Given the perfect square expression 
. Apply perfect square formula:
Knowing laws of exponent is mandatory when it comes to algebra. Recall that:
Apply laws of exponent to simplify the terms or expression:
Since there are no like-terms to do operation with (these terms have different degrees so they are not considered to be like-terms.) Therefore, the final answer is:
Given:
The point is (-2,4).
To find:
Whether the point (-2,4) satisfy 
or 
.
Solution:
We have a point (-2,4).
Substituting x=-2 in 3x+5 and check whether it is greater, equal or less than y value, i.e., 4.
-1 is less than 4.
In can be written as
Therefore, the given point (-2,4) satisfy .
Answer:
S
Step-by-step explanation:
Segment P shows as time is increasing, distance is also increasing. Which means the cyclist is moving forward at a speed.
Segment Q shows that distance is constant but time is increasing. This means that the cyclist is at rest.
Segment R shows as time in increasing, distance is also increasing. Which means the cyclist is moving forward.
Segment S shows that as time increases, distance decreases to the t-axis<em> [ the point where Segment P started, hence original position]</em>. This shows the cyclist returning to the starting point
Correct answers is Segment S.
Answer:
<h2>
not a function</h2>
Step-by-step explanation:
vertical line test: if it intersects at more than one point, it is not a function. If it intersects once, it is a function
New class average: 83
The original average: 82
And if there are 12 students, the total sum of all 12 tests should be
82 x 12 = 984
Then to find the average of the new tests
Add 12 points to the original sum
984+12 = 996
Then divide by 12 to find the new average
996/12 = 83
