Answer:
14/15
Step-by-step explanation:
Find common denominators. Note that what you do to the denominator, you do to the numerator.
Use 15 as the common denominator:
(-2/5)(3/3) = (-6/15)
(4/3)(5/5) = (20/15)
Combine like terms:
-6/15 + 20/15 = (20 - 6)/15 = 14/15
14/15 is your answer.

Answer:
<h3>Right π over 2 Up 2.</h3>
Step-by-step explanation:
We are given a trigonometric function f(x) = −3 cos(2x − π) + 2.
We need to explain the transformations in the given function being applied.
We can see that 2 is being added to −3 cos(2x − π) in th given function.
<em>According to rules of transformations, y=f(x)+D, shifts D units up if D is a positive number.</em>
Therefore, for adding 2 in −3 cos(2x − π), it would shift 2 units up.
Let us see other transformation being applied there.
We can see that π is being subtracted in parenthesis from 2x.
<em>According to rules of transformations, y=f(x-C), shifts C units right if C is a positive value.</em>
Therefore, on subtracting π from 2x in −3 cos(2x) inside parenthesis, the function shifts π units right.
Therefore, correct option for transformations would be :
<h3>Right π over 2 Up 2.</h3>
Answer:
B. (13-6) n - 55
Step-by-step explanation:
The number of shirts to be sold is n
The cost to purchase one shirt is $13
The cost of making each shirt is $6
Let's assume the shirt is one
Profit for a Shirt = (13-6)
But then there are no number of shirts
Profit= (13-6)n
But then also, an advert was run for the total shirts combined
Profit= (13-6)n -55

Answer:
276/47
Step-by-step explanation:
The fractions can be given a common denominator by multiplying the top fraction by 6/6. Then the common denominators can be cancelled.
