The answer is A, because if you square 5, (so, 2x-7 >= 25), then add 7 to both sides, you get 2x >= 32. Now you need to find a number which will result in 2x always being 32 or greater

So do 32/2, which is 16 and your answer is x >= 16

is 48 right

The second one is correct, because linear equations are (correct me if I'm wrong) always consisting of direct variation
