47 is the first one
The first one is A
The second one is...
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
and can u see 49? bc im confussed on that one too.
I haven't done variation in forever, so I'm not sure. Might help to show the answers too
