Solve the equation 6x + 3y = 15 for y. what does y equal if x = 2? if x = 5?

Can someone me with this? i’m not sure what to put for my equations.

Which equation can be solved to find one of the missing side lengths in the triangle? cos(60o) = cos(60o) = cos(60o) = cos(60o) = mark this and return

Fill in the missing exponents in each box and show how you found the answer. (4 points: 2 points for each correct answer with work shown) c. (9^4)^? =9^1 d.(5^? )^3=5^1 *question marks represent the boxes
