Algebra II help please!?

Question

x= - 6 and 1/2y= -12, what is the value of y in terms of x?

Answer choices: x-6
2x-6
2x
1/2x
and 1/4x

My school started on August 10th.

Thank you for your help! :)

(BTW, this was on a school worksheet.)

Answer 1

uhh strange question.. but

you can take x = -6 and multiple both sides by 2 giving you

2x = -12

now plug 2x in for -12 in the second equation

1/2y = 2x.... multiply both sides by y

1/2 = 2xy.... divide both sides by 2x

1 / 4x = y

Answer 2

None of the above. 1/2y=-12 implies that y=-24, i.e. y=4x or 2x-12 or x-18, and each of those answers is obviously different. As such, I suspect that you misprinted the problem. Was your question:

1
-- y = -12
2

or

1
---- = -12
2y

Because if you mean the latter, you should have written 1/(2y). Despite PEMDAS, multiplication has the same priority as division, not greater priority (conceptually, this is because division is considered to be multiplication by the reciprocal - which makes things easier when moving terms around, since multiplication is commutative and associative, and division isn't) As such, if you want us to multiply 2y and then divide 1 by it instead of evalutaing the operations from left to right (which would mean dividing 1 by 2 and then multiplying the resulting 1/2 by y), you have to put the 2y in parentheses.. Anyway, assuming you meant 1/(2y), the answer would be y=1/(4x), because:

1/(2y)=-12
1=-24y
y=-1/24

And 1/(4x) = 1/(4*(-6)) = -1/24

Answer 3

Answer: 1/4x

solve for y:
Take the reciprocal of both sides: 2y = -1/12
Divide both sides by 2: y = -1/24
Plug in -6 for x in each answer choice:
x-6 = -12
2x-6 = -18
2x = -12
1/2x = -1/12
1/4x = -1/24 , which equals y, so this is the answer

Answer 4

first, set both equations equal to zero
x+6=0 and 1/2y+12=0

then set both equal to one another and solve for y

x+6=1/2y+12
subtract 12 from both sides to get y by itself
x-6=1/2y+0
clear fractions by multiplying both sides by 2
2(x-6)=y

but that isn't one of the selections...but double check to make sure you have the right choices listed.

Answer 5

y = -12 * 2 = -24. So, y = 4x

Answer 6

you need to take Algebra II/Trig. i'm presently in Algebra II, and that is somewhat hassle-free... My chum is giving me a pre-calc e book quickly so i'm able to end being bored. in case you like a project decide for the extra tricky direction. you need to sense fortunate that your college has that risk. i understand i'd have down it if I had the possibility.

Answer 7

x-6

Answer 8

x = -6
1/2y = -12, so y=-24
Now for each choice, fill in x and see if you get y.
According to me, none of the given choices is correct.

Answer 9

1/4x

Answer 10

I believe it is 4x, which is not one of your answers...sorry
