Calculate the slope of a line that is perpendicular to y = -4x - 12

the slope of a line perpendicular to y = -4x -12 would be 1/4.

Step-by-step explanation:

perpendicular lines have slopes that are the oposite resiprical of each other.

if the slope of the first line is -4 then the oposite is (+) 4 and the resiprecal 1/4.

m = 1/4

so the slope of the line perpendicular of y = -4x -12 is 1/4.

- 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

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
