Find the center and radius of (x + 8)2 + (y + 4)2 = 49. (8, 4); 7 (–4, 8); 7 (–8, –4); 7

What is the solution of log2  (3x  -  7)  =  3? 4 5

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 number line represents the solution set for the inequality -1/2 greater than or equal to 4
