Zuleika was solving 2(x - 3) - 9 = 3x - 9. zuleika's first step resulted in 2(x - 3) = 3x
because she used the multiplication/addition property of equality. the second
step resulted in 2x - 16 = 3x because she collected like terms used the distributive
properly. in the next two steps, zuleika used the addition/multiplication property
twice to get -x = 6.she then found the solution, x = -6, by using the
addition/multiplication property of equality.

Tell me how you got the it use the figures to answer questions 1and 2. in each diagram, line k is parallel to line l, and line t intersects lines. 1. based on the diagrams, what is the value of x? 2. how would you verify your answer for x?

What properties allow transformation to be used as a problem solving tool

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.
