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

Mathematics

-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.

25 POINTS PLEASE HELP ME!! Sam conjectures that for x ≤ - 2, it is true that x^5 + 7 &gt; x^3. Is Sam’s conjecture correct? Why
CaHeK987 [17]

The true statement about Sam’s conjecture is that the conjecture is not correct

<h3>How to determine if Sam’s conjecture is correct or not?</h3>

Sam’s conjecture is given as:

For x ≤ - 2

It is true that x^5 + 7 > x^3.

The inequality x ≤ - 2 means that the highest value of x is -2

Assume the value of x is -2, then we have:

(-2)^5 + 7 > (-2)^3

Evaluate the exponents

-32 + 7 > -8

Evaluate the sum

-25 > -8

The above inequality is false because -8 is greater than -25 i.e. -8 > -25 or -25 < -8

Hence, the true statement about Sam’s conjecture is that the conjecture is not correct
