Hapter 6 Test How many solutions does the following system have? Choose the explanation that best fits your answer.
y=- 1 +4
4x + 8y = 16
O
A One solution, there is only one point that is a solution to both equations.
0
В.
One solution: both lines cross the y-axis at the same point.
O
C. No solution; the lines are parallel.
O
D. Infinitely many solutions; the equations are equivalent.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
