The inequality 5x - 2y 1 > 0 is satisfied by point (-2, -1). true false

Hello there!

the inequality is (i think):

5x - 2y + 1 > 0

and we wanna see if the point (-2, -1) satisfies this inequality.

If we want to see it, we just need to replace the values x= -2, y = -1 in the inequality and see if it is satisfied:

5x - 2y + 1 > 0

5*(-2) - 2*(-1) + 1 > 0

-10 + 3 > 0

-7 > 0

this is false; then the point (-2, -1) does not satisfy the inequality.

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get
