Answer:
3x^5 - 4x^4 - 5x^3 + x^2 + 11x - 6
Answer:
x = 1/2
and
y = -1
Step-by-step explanation:
8x + 3y = 1
4x + 2y = 0
Multiply 4x + 2y = 0 by 2
8x + 3y = 1
8x + 4y = 0
8x + 4y = 0 minus 8x + 3y = 1
y = -1
For 8x + 3y = 1 plug in y = -1
8x + 3(-1) = 1
8x - 3 x 1 = 1
8x - 3 = 1
Add 3 to both sides
8x - 3 + 3 = 1 + 3
8x = 4
Divide both sides by 8
8x/8 (cancels out) = 4/8
x = 1/2

Answer: C) -48x^7y^3 </h3>
Explanation:
The coefficients are -8 and 6, which are to the left of the variable expressions. The coefficients multiply to -48. Based on this alone, the answer is between choice C or choice D.
For the variables, we add the exponents. The x terms multiply to x^5*x^2 = x^(5+2) = x^7
The y terms multiply to y^2*y = y^2*y^1 = y^(2+1) = y^3
Putting everything together, we end up with -48x^7y^3
