The inequality x - y > 0 is satisfied by point (-1, 1). T/F

Mekhanik [1.2K]

-2 is not greater than zero, so, the point don't satisfy the inequality x - y > 0

Hence correct option is false.

Step-by-step explanation:

We need to identify the point (-1,1) satisfies the inequality x - y > 0

Solving:

The value of x = -1 and y =1

Putting values in the inequality:

$x-y>0\\-1-1>0\\-2>0\,\,false$

-2 is not greater than zero, so, the point don't satisfy the inequality x - y > 0

Hence correct option is false.

Please help me with this math question

Svetach [21]

If the two rectangles are similar, their sides must be proportional. We can figure this out by setting up a proportion. We need to make sure to match up the correct sides though. We know the two longer sides must match up, so 6 goes with 60, and 3 goes with 30:

3/6=30/60

If we reduce the fractions, we get:

1/2=1/2

Therefore, the rectangles are similar. One of them is just rotated.
