Answer:
178 - 3x.
Step-by-step explanation:
The three angles in a triangle add up to 180 degrees so an expression for the third angle is:
180 - (x + 9) - (2x - 7)
Distributing the negative over the parentheses, we have
180 - x - 9 - 2x + 7
= 180 - 9 + 7 - x - 2x
= 180 - 2 - 3x
= 178 - 3x (answer).
Answer:
x = how many fish they catch. The graph represents that how many fish the person catches and how much it is. x basis is money y basis is the fish caught.
Step-by-step explanation:

Assuming equation 2 is y = (2/3)x-6, then the answer is A) Parallel.
Solve 2x-3y = 6 for y and you'd get y = (2/3)x-2. The slope here is 2/3 as it is for equation 2 as well. The slopes are the same but y intercepts are different, so the lines are parallel.
Answer:
B. 2n + 1.
Step-by-step explanation:
This is an arithmetic series with first germ 3 and common difference 2.
The nth term (an) = a1 + d(n - 1)
= 3 + 2(n - 1)
= 2n + 3 - 2
= 2n + 1.
