Answer from: beccahaileyowzryu

Answers:
options a, b, c and e are correct
explanation:
to get the correct choice(s), we will simply compute the given equation for each of the given values and check whether the given order pair satisfies the equation or not.
option a:
for the order pair (-3,-2):
y < 0.5 x²
-2 < 0.5(-3)²
-2 < 4.5
the equation is > this option is correct
option b:
for the order pair (-2,1):
y < 0.5 x²
1 < 0.5(-2)²
1 < 2
the equation is satisfied > this option is correct
option c:
for the order pair (-1,-2):
y < 0.5 x²
-2 < 0.5(-1)²
-2 < 0.5
the equation is satisfied > this option is correct
option d:
for the order pair (-1,2):
y < 0.5 x²
2 < 0.5(-1)²
2 < 0.5
the equation is not satisfied > this option is incorrect
option e:
for the order pair (1,-2):
y < 0.5 x²
-2 < 0.5 (1)²
-2 < 0.5
the equation is satisfied > this option is correct
option f:
for the order pair (1,2):
y < 0.5 x²
2 < 0.5 (1)²
2 < 0.5
the equation is not satisfied > this option is incorrect
hope this : )

Answer from: smarcelle

a)

c)

e)

f)

step-by-step explanation:

we have

we know that

if a ordered pair is a solution of the inequality

then

the ordered pair must be satisfy the inequality

verify

point a)

substitute the value of x and value of y in the inequality an compare

> is true

the ordered pair is a solution of the inequality

point b)

substitute the value of x and value of y in the inequality an compare

> is not true

the ordered pair is not a solution of the inequality

point c)

substitute the value of x and value of y in the inequality an compare

> is true

the ordered pair is a solution of the inequality

point d)

substitute the value of x and value of y in the inequality an compare

> is not true

the ordered pair is not a solution of the inequality

point e)

substitute the value of x and value of y in the inequality an compare

> is true

the ordered pair is a solution of the inequality

point f)

substitute the value of x and value of y in the inequality an compare

> is true

the ordered pair is a solution of the inequality
