The inequality x - y > 0 is satisfied by point (-1, 1).<br><br> 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.

Can someone please help me

svp [43]

Answer:

m < 2 = 137°

m < 4 = 137°

Step-by-step explanation:

Given that m < 7 = 43°, we can say that it has the same measure as < 3 because they are corresponding angles. Thus, we can establish that m < 3 = 43°.

We can use m < 3 = 43° to find m < 4, as they are supplementary angles that have a sum of 180°.

Therefore:

m < 3 + m < 4 = 180°

Rearrange the formula to isolate m < 4:

m < 4 = 180° - m < 3

Substitute the value of m < 3 into the rearranged formula:

m < 4 = 180° - m < 3

m < 4 = 180° - 43°

m < 4 = 137°

Therefore, m < 4 = 137°.

< 2 and < 4 also have the same measure because they are vertical angles. Two angles are vertical angles if they are opposite angles formed by the intersection of two lines.

Hence, m < 2 = 137°
