Seems to be right. sorry if i am wrong
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.
Since you're only interested in x, you can use the first equation to write an expression for y that can be substituted into the second equation.
.. y = k -x
.. 2x +3(k -x) = k +1
.. -x +3k = k +1 . . . . . collect terms
.. 2k -1 -x = 0 . . . . . . subtract k+1
.. 2k -1 = x . . . . . . . . .add x
The 3rd selection is appropriate.
Answer:
P(blue)= 0.25 or 1/4
Step-by-step explanation:
On this spinner, each spot is the same size; therefore, there is a 1 in 4 chance that the spinner lands on blue. This is because there are 4 options but only one of them is blue. Then, if you want a decimal just divide 1 by 4. This equals 0.25. Additionally. If you wanted the answer as a percentage multiply the decimal by 100, so the percentage would be 25%.
