Answer:
∠2 and ∠6
Step-by-step explanation:
Supplementary means that the angles added are a total of 180°.
∠5 and ∠8 are supplementary because they form a line, and a line is 180°.
∠1 and ∠2 are supplementary because they also form a line.
∠4 and ∠5 are supplementary because they are same side interior angles, and same side interior angles are always supplementary.
Only ∠2 and ∠6 are not supplementary because they are corresponding angles, and corresponding angles are congruent, not supplementary.
For a) you would start at positive 4 then go up 2 then right 2 and repeat that

Answer:
The maximum number of mosquitoes is 7
Step-by-step explanation:
Given
Required
Determine the maximum number of the function
First, we differentiate the given function w.r.t x
Then, we equate m'(x) to 0
Lastly, we solve for x
Make 2x the subject
Make x the subject
Let x be the cost of each book.
So, the cost of 4 books is 4x.
For the purchase of 4 books, he got a discount of $20.
So, the amount he paid for the first four books = 4x - 20.
Now, the cost of 5 books is 5x.
For the purchase of 5 books, he got another discount of $5.
So, the amount he paid for the five books = 5x - 5.
Total money spent = $87.
Therefore, (4x - 20) + (5x - 5) = 87
4x + 5x - 20 - 5 = 87
9x - 25 = 87
9x = 87 + 25
9x = 112
Divide both sides by 9.
x = 12.4
Hence, the cost of each book = $12.4.
