2. So for this question, you do the distributive property, which is multiplying the term outside of the parenthesis by the terms in the parenthesis. In this case, the outside term is 1/2. 8x * 1/2 = 4x and 1/2 * -16 is -8. That brings us to 4x - 8, which is our answer. Therefore, the correct answer choice is B.
3. Okay. In this problem, we are talking about the sum of 12 and a number. That's 12 + n, because sum means the answer to the addition problem D is out, because we don't do distributive property in this case. The sum of 12 + n is 4n. The expression is 12 + n = 4n. The answer is B.
Cross multiplying:-
18*x = 12*30
x = 360 / 18
x = 20 answer
I believe it’s A because if it is perpendicular you would have to flip 6X and change the sign so therefore it would be A. In slope intercept form it would be y=-6x+1.
22. The range of the arcsine function (sin⁻¹(x)) is [-π/2, π/2]. The function will return π/4 for arcsin(sin(3π/4)) = arcsin(1/√2).
The sine function does not pass the horizontal line test, so it has no inverse over its entire domain. The arcsine function is only the inverse of the sine function over a limited domain/range.
25. sin(cos(π/2)) = sin(0) = 0.
As with any nested function evaluation, you evaluate the inner function first.
... cos(π/2) = 0
Then you evaluate the outer function.
... sin(0) = 0
