Which of the following is the solution to | x | +5< 1?
A. X<-4
B. X<-4 and X>-6
C. No solution
D. All values are the solution

C. No Solution

Explanation

The above equation has no solution as the value of x is always mod x which means the value is always positive. Hence to make the equation true, we need value of mod x less than -4 which is not possible. Hence this equation as no solution.

Since, |x| can never be < -4 because value of |x| is always greater than or equal to, Hence this equation has no solution.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
