Step-by-step explanation:
Answer:
D. 20
Step-by-step explanation:
First, we need to plug in -2 to all the spots where x are. The new equation we have then is f(-2)= 2(-2)^2 - 3(-2) + 6. Then, we plug in the exponent to get 2(4) - 3(-2) + 6. We can then multiply to get 8 + 6 (since the three was negative as well) + 6, which equals 20.
Answer:
Sin(F) = 12/13
Cos(F) = 5/13
Tan(F) = 12/5
Step-by-step explanation:
Sin = Opp./Hypo, Cos = Adj./Hypo. and Tan = Opp./Adj.
So
Sin(F) = Opp./Hypo = 12/13
Cos(F) = Adj./Hypo = 5/13
Tan(F) = Opp./Adj. = 12/5
A) He wanted to create zero pairs on the left side of the equation to get a positive coefficient of x on the right side
X+7.5=21.5
Subtract 7.5 from both sides
X=14 which is C
hope this helps good luck have a nice day
