80÷12= 6 2/3
12×12×12×12×12×12=72
so 12 goes into 80 evenly 6 times, but there is a remainder so you have to include it
80-72=8
so that leaves you with 8/12 which is 2/3 when simplified
now you have 6 + 2/3 = 6 2/3

Please, use parentheses to enclose each fraction:
y=3/4X+5 should be written as <span>y=(3/4)X+5
Let's eliminate the fraction 3/4 by multiplying the above equation through by 4:
4[y] = 4[(3/4)x + 5]
Then 4y = 3x + 20
(no fraction here)
Let 's now solve the system
4y=3x + 20
4x-3y=-1
We are to solve this system using subtraction. To accomplish this, multiply the first equation by 3 and the second equation by 4. Here's what happens:
12y = 9x + 60 (first equation)
16x-12y = -4, or -12y = -4 - 16x (second equation)
Then we have
12y = 9x + 60
-12y =-16x - 4
If we add here, 12y-12y becomes zero and we then have 0 = -7x + 56.
Solving this for x: 7x = 56; x=8
We were given equations
</span><span>y=3/4X+5
4x-3y=-1
We can subst. x=8 into either of these eqn's to find y. Let's try the first one:
y = (3/4)(8)+5 = 6+5=11
Then x=8 and y=11.
You should check this result. Subst. x=8 and y=11 into the second given equation. Is this equation now true?</span>
The answer is D, because that is what you should get when you multiply it out.
4x^2 times x^2 = 4x^4 because...
1) multiply the 4 and the one in front of the x on the second term = 4 then
2) multiply x^2 times x^2 to get x^4, not x^3, so you can immediately eliminate A and B to save time.
Now let's deal with the second part..."may or may not be" part
A polynomial is an expression with more than two algebraic terms
terms are like...
2x + 3y ---there's two terms there, eventhough the 2 and x are multiplied, it doesn't count (same with the 3 and y)
since it only have two terms, not more than two terms, it is called a binomial, not polynomial. I think that's what they mean by that
one term with a variable (y,x,and so on) is called a monomial
one term with no var is called a constant
there's many more but hope this gave you some help
