Two vertices of a rectangle are (3,7) and (4,-7). If the rectangle has a perimeter of 30 units

What is the solution to the system of equations? (–2, –8) (–1, –5) (0, –2) (2, 4)

Use the graph of the sine function y=2sinθ shown below

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.
