Which of the following is the solution set of -21xl <-8? {x1-4>x>4]
{XIX<-4 or x 34)
{x1-4

x>4 or  x <-4

Step-by-step explanation:

-2|x| < -8

Divide each side by -2, remembering to flip the inequality

-2|x|/-2 > -8/-2

|x| >4

To get rid of the absolute values, we get 2 equations one positive and one negative

x>4 or  x <-4

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
