Step-by-step explanation:

<u>Step 1: Define</u>

2x³y³ + 3xy - 3x³y³ + x²y - xy + 2x²y

x = -1

y = 2

<u>Step 2: Evaluate</u>

  1. Substitute:                                                                                                2(-1)³(2)³ + 3(-1)(2) - 3(-1)³(2)³ + (-1)²(2) - (-1)(2) + 2(-1)²(2)
  2. Exponents:                                                                                                         2(-1)(8) + 3(-1)(2) - 3(-1)(8) + 1(2) - (-1)(2) + 2(1)(2)
  3. Multiply:                                                                                                             -16 - 6 + 24 + 2 - (-2) + 4
  4. Simplify:                                                                                                                -16 - 6 + 24 + 2 + 2 + 4
  5. Subtract:                                                                                                             -22 + 24 + 2 + 2 + 4
  6. Add:                                                                                                                    2 + 2 + 2 + 4
  7. Add:                                                                                                                      4 + 2 + 4
  8. Add:                                                                                                                   6 + 4
  9. Add:                                                                                                                     10

What is the y-intercept of a line perpendicular to y=1/2x + 6 that passes through the point (4,-3)
SCORPION-xisa [38]

Answer:

(0,5)

Step-by-step explanation:

Perpendicular lines have slopes which are negative reciprocals of each other. The slope of the line y=1/2x + 6 is 1/2. The slope perpendicular to it is -2.

Using m=-2, substitute it and (4,-3) into the point slope form and simplify to find the y-intercept.

y-y_1 = m(x-x_1)\\y--3=-2(x-4)\\y+3=-2(x-4)\\y+3=-2x+8\\y=-2x+5

The equation is now in slope intercept form y=mx+b and b is the y-intercept. The y-intercept of y=-2x+5 is (0,5).
