Solve the inequality 2x + 8 < 5x − 4. (5 points) x > 4 x > 1 x < 1 x < 4

x > 4

Step-by-step explanation:

2x + 8 < 5x - 4

2x - 5x < - 4 - 8

-3x < -12 / : (-3)

In a case where you have to divide by a negative number in an inequality, YOU MUST CHANGE THE SIGN REMEMBER THAT IT'S WILL SAVE YOU FROM DOING A SMALL BUT A STUPID MISTAKE

x > 4

1. minimum

2. 6400

3. eight

hope this !

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
