first you divide 48 by 4
48 ÷ 4 = 12
So each cake will need to be cut into 12 pieces
the answer 
and 12 pieces
Answer:
Polynomials of degree 8 have exactly 8 roots
Step-by-step explanation:
The Fundamental Theorem of Algebra states that every polynomial of degree n
with
has exactly n roots.
But the roots may be complex numbers.
In your case n=8, so polynomials of degree 8 have exactly 8 roots.
The roots need not be different.
For example, for the polynomial
x=2 is root twice.

I used mathway to answer this and it said it was -6y(to the second power)+8y
Answer:
A. (3, -3)
Step-by-step explanation:
Let's use the addition/elimination for this to avoid fractions. You could solve one of the equations for y or x and then sub that value into the other equation, but you would have to deal with fractions along the way, so let's just not. Using the addition/elimination (they're the same thing; math books sometimes use one or the other), we line up our equations:
5x + 2y = 9
2x - 3y = 15
It looks like if we want to eliminate the y terms, we can multiply the top equation by 3 and the bottom equation by 2 to get a whole new set of equations:
15x + 6y = 27
4x - 6y = 30
Now we can see that when we add down the columns, the y's cancel each other out. 6y's minus 6y's leaves us with no y's. What we are left with is
19x = 57 so
x = 3.
Now we will sub that 3 back in to either of the original equations to solve for y:
2(3) - 3y = 15 and
6 - 3y = 15 and
-3y = 9 so
y = -3
The solution set then is (3, -3)
