Answer:   4p + 18q - 5m - 6 + 7m²

<u>Step-by-step explanation:</u>

(4p + 2q) - (2m - 7q + 5) + (7m² - 3m + 9q - 1)

distribute the negative sign:

4p + 2q - 2m + 7q - 5 + 7m² - 3m + 9q - 1

group the like terms:

4p + (2q + 7q + 9q) + (-2m - 3m) + (-5 - 1) + 7m²

combine like terms:

4p + 18q - 5m - 6 + 7m²

a line is perpendicular to y=-2x+5 and intersects the point (-4,2). what is the equation of this perpendicular line?
german

Answer:

y = 1/2x + 4

Step-by-step explanation:

If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.

So solve for b: using y = mx + b

2 = 1/2(-4) + b

2 = -2 + b

4 = b

Put it all together

y = 1/2x + 4
