Question

solve using a graph in a number line 8x-8<= -24,x€z
​

Answer 1

Answer:

This is kind of a very simple question as this is just inequality in one variable , what you'll be doing first of all is :-

Step-by-step explanation:

Find the solution for 8x-8 = - 24 , x€z (rational numbers) _____ eq(1)

you'll see the solution is X= -2;

Now by the equation(1) I know that for X= -2,

8x-8=24 is true , now it is self evident that for any X<-2 the

value of 8x-8 is lesser than -24 .

e.g. put X = -4 which is less than -2

you will get 8(-4) - 8 = -40 which is less than -24.

We have to find solution for 8x-8<=24 .

thus by EQ(1) we know that for any X<=-2our

inequality 8x-8 = -24 will be true .

thus solution for the given inequality is

X € (- infinity,-2] .
