Answer:
-19
Step-by-step explanation:
Take the second term and subtract the first term to find what we are adding (or subtacting ) each time
-7 -(-3) =
-7+3
-4
We are subtracting 4 each time
Subtract 4 from the next term
-15 -4 = -19
The next term is -19
The regular rolls are 15x - 2y = 4
The vegetarian rolls 20x - 3y = 1
So the values are:
x = 2 and y = 13
The result is, 2 chefs and 13 customers.

Answer:
3/5
Step-by-step explanation:
We need to use the trig identity that cos(2A) = cos²A - sin²A, where A is an angle. In this case, A is ∠ABC. Essentially, we want to find cos∠ABC and sin∠ABC to solve this problem.
Cosine is adjacent ÷ hypotenuse. Here, the adjacent side of ∠ABC is side BC, which is 4 units. The hypotenuse is 2√5. So, cos∠ABC = 4/2√5 = 2/√5.
Sine is opposite ÷ hypotenuse. Here, the opposite side of ∠ABC is side AC, which is 2 units. The hypotenuse is still 2√5. So sin∠ABC = 2/2√5 = 1/√5.
Now, cos²∠ABC = (cos∠ABC)² = (2/√5)² = 4/5.
sin²∠ABC = (sin∠ABC)² = (1/√5)² = 1/5
Then cos(2∠ABC) = 4/5 - 1/5 = 3/5.
Answer:
EH
Step-by-step explanation:
Since this is a parallelogram the side of the bottom quadrilateral must be parallel so EH must be parallel to FG
