For Exercises 53–68, determine if the equations represent parallel lines, perpendicular lines, or neither. (See Examples 5–6.) l 1 : 2 x + 3 y = 6 l 2 : 3 x − 2 y = 12
For Exercises 53–68, determine if the equations represent parallel lines, perpendicular lines, or neither. (See Examples 5–6.) l 1 : 2 x + 3 y = 6 l 2 : 3 x − 2 y = 12
Solution Summary: The author explains that the pair of equations 2x+3y=6 and 3x-2y =12 are parallel, perpendicular, or neither of the two.
In Exercises 11–12, find the solution set for each equation.
11. |5x + 3| = 7
12. |6x + 1| = [4x + 15||
The bar graph shows the percentage of households with an interfaithmarriage in 1988 and 2012. Also shown is the percentage of households in which a person of faith is married to someone with no religion.The formula I =1/4x + 26 models the percentage of U.S. households with an interfaith marriage, I, x years after 1988.The formula N =1/4x + 6 models the percentage of U.S. households in which a person of faith is married to someone with no religion, N, x years after 1988.In which years will more than 33% of U.S. households have an interfaith marriage?
A traffic safety engineer was studying travel patterns along a highway. She set up a camera and recorded the speed and direction of cars and trucks that passed by the camera. Positions to the east of the camera are positive, and to the west are negative.
1.Here are some positions and times for the carposistion (feet): -180, -120, -60 0 60 120Time (seconds) : -3,-2,-1,0,1,2In what direction is the car traveling East or west?What is its velocity? (Answer should look like "# f/s direction")
