Which linear function is represented by the graph?
f(x) = -2x + 1
f(x) = -4x+1
f(x) = { x +1
f(x) = 2x + 1

The table shows a pattern of exponents. what is the pattern as the exponents decrease?

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.
