Charles charges $4 an hour to baby-sit. He also adds an extra $10 onto the total for families with more than three children. Write an equation for what Charles charges to baby-sit a family of 4 children. y = 4x - 10

y = 4x + 10

y = 40x

y = 4x + 10x

Which is an accurate comparison of the two data sets? the commute to work is typically shorter and more consistent than the commute home. the commute to work is typically shorter but less consistent than the commute home. the commute to work is typically longer and less consistent than the commute home. the commute to work is typically longer but more consistent than the commute home.

What are the solutions of the equation x4 + 6x2 + 5 = 0? use u substitution to solve.

If the equation of a line containing the midsegment of a triangle is y = -1/4x -11, what is the slope of the triangle side that is opposite the midsegment (the one not touching it). explain how you know.
