Transcript of Algebra 2 Mid-TermReview. Simplify: 2/5(10x -15) = 7.
Show the steps clearly and completely as you solve. Round your answer to three correct decimal places.
• 14.5 – 3.7x = 8.9x + 23.79
Which of the following is not a function.
• A) (9,0),(3,4),(-7,12)• B) (4,5), (4,5),(3,-2)• C) ( 7,9),(-8,4),(2,9)• D) (-6,4),(8,1),(-6,4)
Which of the following is not a function.
• A) (5,1),(13,8),(-7,8)• B) (14,0), (14,7),(-3,-9)• C) ( -1,9),(-8,9),(12,9)• D) (-6,4),(8,1),(9,12)
Show the steps carefully and completely as you find the inverse of the function. Graph the equation and the inverse.
