Answer:
The answer to your question is: letter J is the right answer
Step-by-step explanation:
3x - 4y = 6
Solve for y
Add - 3x in both sides 3x - 3x - 4y = -3x + 6
Simplify -4y = -3x + 6
Divide by -4 -4/-4 y = -3/-4 x + 6/-4
Simplify y = 3/4x - 6/4
y = 3/4 x - 3/2
Write it as a power of 10
200 x 10
2 x 10^2
It
would be: Quadratic -x^2 + 2x - 3. Because if we do x = 3,

Answer:
The given expression
on multiplying is 
Step-by-step explanation:
Consider the given two expressions
and 
We have multiply both expressions,

To multiply two terms first multiply constant numbers that is 6 × 2 = 12
For x , y and z apply property of exponent,

Then power of x together will be,

Similarly for y powers,

Since first term do not have any expression for z so it will remain same.
Thus, the given expression on multiplying become,
is
