Answer:
m =3/4
Step-by-step explanation:
3x-4y = 12
We need to solve for y
Subtract 3x from each side
3x-3x-4y = -3x+12
-4y = -3x+12
Divide by -4
-4y/-4 = -3x/-4 + 12/-4
y = 3/4 x -3
This is in the form y = mx+b where m is the slope and b is the y intercept
The slope is 3/4
Answer:
25
Step-by-step explanation:
32% = 32/100 = 0.32
Let the unknown number be x.
0.32 x = 8
x = 25
Here's the rule for working with these things:
There are 3 signs associated with a fraction:
=> the sign of the numerator
=> the sign of the denominator
=> the sign of the whole fraction; (if the fraction were in
parentheses, this sign would be written outside).
-- You can change any 2 of them without changing the value of the fraction.
-- Changing any 1 of them changes the effective sign.
___________________________________
Now, you said the fraction is negative.
So, let's start with the positive fraction, and see the different ways
that we could make it a negative fraction:
=> mark only the numerator negative
=> mark only the denominator negative
=> put parentheses around the fraction, and mark it negative outside
If you do any one of these things to a normal positive fraction,
it turns into a negative fraction.
Look at the choices you listed in the question:
-- in the numerator only ? Yes. That makes it a negative fraction.
-- in the denominator only ? Yes. That makes it a negative fraction.
-- both ? No. That makes it the same as a positive fraction.
-- put parentheses around the fraction, and a negative sign outside ?
Yes. This makes it a negative fraction.
-- it doesn't matter ? No. I hope you can see that it does matter.
Have I confused you ?
Is this more than you wanted to know ?
Here is your answer
<u>EXPLANA</u><u>TION</u>
Here, we multiply <em><u>numerator</u></em> of one fraction to the <em><u>numerator</u></em> of the other fraction and similarly the <em><u>denominators</u></em> of both fractions are multiplied.

Linear dimensions will be in the ratio
12/18 = 2/3
areas (all of them) will have the ratio
4/9
volumes will have the ratio 8/27
