Answer:

-2<x<3

or x∈(-2,3)

Step-by-step explanation:

x²-5x<-6

add (-5/2)² i.e.,25/4

x²-5x+25/4<-6+25/4

(x-5/2)²<(-24+25)/4

(x-5/2)²<1/4

(x-5/2)²<(1/2)²

|x-5/2|<1/2

-1/2<x-5/2<1/2

Add 5/2

-1/2+5/2<x-5/2+5/2<1/2+5/2

-2<x<3

Last year the vending machine sold drinks for $1.25. This year the price is $1.50. What is the percent of markup?
Ann [662]

The percent of markup is 20%

Step-by-step explanation:

Selling price of the drink = $1.50

Cost of the drink last year = $1.25

Percent of markup = (selling price - cost) (100)/cost

Percent of markup = (1.50 - 1.25)(100) /1.25

= 0.25(100) /1.25

= 25/1.25

= 20%

The percent of markup is 20%

4. Can two lines be parallel and perpendicular? Explain.
lidiya [134]

Answer: No

Step-by-step explanation: First, we need to understand that parallel lines are coplanar lines that do not intersect. On the other hand, perpendicular lines are lines that intersect at a right angle.

However, lines can't be both parallel and perpendicular because they either intersect each other at a right angle or never intersect.

So no, two lines can't be both parallel and perpendicular.
