[QUOTE="emilyt:1, post: 2267516, member: 702486"] I'm stuck....can someone please explain how to solve these problems? 1) f(x) = x2 - 1 g(x) = x - 1 Find (g o f) (x) a. x^2-2 b. x^2-2x c.x^2-2x-1 d.x^2-2x-2 2) Which of the following is the solution to the inequality -2(x-3) < -x+3? a. x> 3 b. x< 3 c. x>1 d. x>-3 3) Write the equation of the line that passes through the points (2,5) and (6,2). a. y=-3/4x+15/2 b. y=3/4x+7/2 c. y=-3/4x+23/4 d. y=-3/4x+13/2 4) Solve the literal equation Ax - By = C for x a. x=C/Ay+B b. x=C+By/A c. x=C-(A-B)/y d. x=C/A-By 5) What is the vertex of the parabola y = -3(x - 4)^2 - 5? a.(4,-5) b.(-3,-5) c.(-3,4) d.(3,-4) 6) Is 9x2 + 12xy + 9y2 a perfect square trinomial? a. yes b. no 7) In solving this system by the substitution method, what is the expression for x that you will substitute into the second equation? {x-4y=13 {2x+3y=-7 a. x = 13 - 4y b. x=-7+3/2x c. x = 4y + 13 d. none of the above 8) If a quadratic equation has 2 unique rational roots, how many times will its graph intersect the x-axis? a. Zero times b. One time c. Two times d. Three times 9) When x2 - 7x - 8 is factored completely, one of the factors is a. (x-1) b. (x-2) c. (x-8) d. (x+2) 10) The graph of the system {3x+2y=5 consists of two lines that: {6x+4y=10 a. Intersect at one point b. Intersect in an infinite number of points c. Are not in the same plane d. Do not intersect Thank-you!!! [/QUOTE]
