Solve the following inequality: x^2-8x + 7> 0

The solution lie in  

Step-by-step explanation:

Given : Inequality

To find : Solve the inequality?

Solution :

First we convert the inequality into equation,

Solving by middle term split,

Use each root to create test intervals,

For x<1, let x=0

True.

For 1<x<7, let x=3

False.

For x>7, let x=8

True.

Therefore, The inequality form is x<1 or x>7.

The interval notation is

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
