Given ƒ(x) = 2/3 x - 1, complete parts a and b. part

a: using the table provided, create five points to demonstrate that for the function, ƒ(x) = 2/3 x - 1, there is exactly one output value for each corresponding input value. in your final answer, include all calculations and the completed table. x y

part b: on a separate sheet of paper, use the points created in part a to graph the function, ƒ(x) = 2/3 x - 1. label the values on the x- and y-axes, and all points on the graph.

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.

What is the value of x when x + 7 = 21?

Michelle and julie work at a catering company. they need to bake 264 cookies for a birthday party that starts in a little over an hour and a half. each tube of cookie dough claims to make 36 cookies, but michelle eats about 1/5 of every tube and julie makes cookies that are 1.5 times as large as the recommended cookie size. it takes about 8 minutes to bake a container of cookies, but since julie's cookies are larger, they take 12 minutes to bake. a. how many tubes should each girl plan to bake? how long does each girl use the oven? b. explain your solution process what did you make? c. what assumptions did you make?
