Answer:

  A)  5x+12 = -12x-12

  D)  5x+12 = -5x-12

Step-by-step explanation:

If you subtract the right side expression from both sides, you will get an equation with something equal to zero. If the 'something' has a variable in it, there is exactly one solution.

A: (5x+12) -(-12x-12) = 17x+24 = 0 . . . one solution

B: (5x+12) -(5x-5) = 17 = 0 . . . . no solutions

C: (5x+12)-(5x+12) = 0 = 0 . . . . infinite solutions

D: (5x+12) -(-5x-12) = 10x +24 = 0 . . . one solution

What is an explicit equation?
artcher [175]
An explicit equation is an equation used to find a term in a sequence without using the any previous terms. For example, if I have the set of numbers 1, 3, 5, 7, 9, my explicit equation is F(n)=2(n-1)+1. If I plug 1 in for n, I get F(1)= 2(0)+1, which is 1, my first term.

Hope this made sense.

The value of the expression 16 -3/4 is ______.
Korvikt [17]
16-3/4=15 1/4

You can convert to fractions first, and then convert back to a mixed number like:

16/1-3/4  and when you add/subtract fractions you need a common denominator

64/4-3/4

61/4

15 1/4

Or you can convert your fraction to a decimal to get:

16-0.75

15.25
