Answer:
y = 5
Step-by-step explanation:
AB = | 8 - (- 4) | = | 12 |= 12
Divide 12 by the sum of the parts of the ratio, 1 + 3 = 4
12 ÷ 4 = 3
Thus
y = 8 - 3 = 5
Answer:

Step-by-step explanation:
I'm going to write 105 as a sum of numbers on the unit circle.
If I do that, I must use the sum identity for sine.


Plug in the values for sin(60),cos(45), sin(45),cos(60)



If sandys friends ate 0, 2, 3, 4, 6, 6, and 7 pretzels, the mean of the data would be 4. So yes sandy is correct.
It depends on the question, but if the questions is sort of like "Person A and Person B shared 40 sweets in the ratio 3:5, how many sweets did Person A get" then you add 3 and 5 to get 8, and then you do 40 ÷ 8 to get 5 which is 1 in terms of the ratio. Then, you would multiply 5 by 3 to get 15 sweets. If it's a different type of question then let me know so I can help out :)

Step-by-step explanation:
You have not provided the options to help us give you a specific answer.
If a quadratic function is written in the form

Then (h,k) is the vertex, and 'a' is a constant.
For instance

has vertex at (2,3).
Also, an absolute function in the form

has vertex at (h,k).
This means

also has vertex at (1,3).
I hope this explanation is helpful.
