quotient is divide 7 ÷ -3/6
now flip the -3/6
7/1 x -6/3 = -42 / 3 or -14
I'm doing interval notations right now in pre-calculus, this how this notation should be written, (-∞,-2] or [4,∞), but this, (x ≤ -2] or [4 ≤ x), means the same thing. closed circle gets a bracket and an open circle gets a parenthesis, infinity always gets a parentheses because it is not a number. hope this helps
Each shirt is bought for eight dollars and sold for twelve, so there is four dollars profit per shirt. The twenty dollar constant, however, needs to be covered by the profit.
The inequality is
100>=4x-20
120>=4x
30>=x
The club needs to sell at least 30 shirts to make a profit of at least $100
