Write an equation for a line parallel and a line perpendicular to the given line that passes through the given point.
11. 2x + 3y = 6; (-2,-6)
12. -4y + x + 12 = 0; (5,3)
13. y=-4x + 6; (1, 1)
14. y= 1/3x- 5; (-4, 2)

Do 12/14 and 8/10 have the same value? explain your answer.

The manufacturer of a new product developed the following expression to predict the monthly profit, in thousands of dollars, from sales of the productwhen it is sold at a unit price of x dollars.-0.5x^2 + 22x - 224what is represented by the zero(s) of the expression? a. the profit when the unit price is equal to 0b. the unit price(s) when the profit is equal to 0c. the profit when the unit price is greatestd. the unit price(s) when profit is greatest

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
