Answers:
Additive Inverse = 1/2
Multiplicative Inverse = -2
========================================
Explanation:
The additive inverse of x is -x. The two add to 0.
So the additive inverse of -1/2 is 1/2 because -1/2+1/2 = 0.
--------------
The multiplicative inverse of x is 1/x
More thoroughly, the multiplicative inverse of a/b is b/a.
We apply the reciprocal operation here.
That means the multiplicative inverse of -1/2 is -2/1 which simplifies to -2.
We can see that (-1/2)*(-2) = 1
Any nonzero value multiplied with its multiplicative inverse will always result in 1.
Answer:
A. -1/8x + 3/16
Step-by-step explanation:
-1/2(1/4x - 3/8)
Distribute the -1/2 into both the terms in the equation.
-1/2 * 1/4x = -1/8x
-1/2 * -3/8 = 3/16
Now combine both the expressions.
This makes your answer A,

Answer: 11.2 inches</h3>
Work Shown:
(real height)/(scale height) = (real length)/(scale length)
(10 feet)/(8 inches) = (14 feet)/(x inches)
10/8 = 14/x
10x = 8*14
10x = 112
x = 112/10
x = 11.2 inches
Answer: B is the correct choice
Step-by-step explanation:
The values are essentially the same. You need to recognize how the symbols in the expressions match up with the symbols on the graph.
The open circle on the right end of the parabola means the function is less than (not including) 2 so <2 for that part.
The solid circle at the left of the line means f(x) includes all the values to the right are greater than or equal to 2 so ≥2 for that part.
