Question 63871: A home-based company produces both hand-knitted scarves and sweaters. The scarves take 2 hours of labor to produce, and the sweaters take 14 hours. The labor available is limited to 40 hours per week, and the total production capacity is 5 items per week. Write a system of inequalities representing this situation, where x is the number of scarves and y is the number of sweaters. Then graph the system of inequalities.

Question 64038: How do you write an equation of a line when given two pionts and a slope, but the other line must be perpendicular.....Example from my homework:
Write an equation of a line that contains the given point and is perpendicular to the given line
#1. (5,1); y=5x-2
And how would you solve one of these equations when given a graph with a line with a slope on it??
Thank you!

Question 64321This question is from textbook college algebra
: I really need help, I am an adult struggling with algebra. I have a very hard time starting out the problem. This specific problem I need to find the x intercept of
y = x^3-2x^2-8x
I think this is how I would start the problem
(x^2-4) (x+2)
and then foil it but I really am stuck.... Please help me thank you.This question is from textbook college algebra
