What are the solutions of |x+6| greater than or equal to 5? Write the solutions as either the union or the intersection of two s

sukhopar [10]

We have that
 |x+6| >= 5
step 1
resolve for (x+6)>=5------> x>=5-6-------> x>= -1
the solution is the interval (-1, ∞)

step 2
resolve for -(x+6) >=5------> -x-6 >=5----> -x >= 5+6---> -x>=11----> x<=-11
the solution is the interval (-∞, -11)

using a graph tool
see the attached figure

the solution is the interval (-∞, -11) ∩ (-1, ∞)

Each week carrie works 40 hours she spend 15% of her time at register

VLD [36.1K]

Please, share the goal of the problem. If Carrie works 40 hours per week and spends 15% of her time at the register, how much time does she NOT spend at the register?

Subtract 15% from 100%; the result is 85%. Now find 85% of 40 hours:

0.85(40 hours) = 34 hours.

Please note that I invented part of this problem. Next time, share all of the info so that someone can help you solve YOUR particular problem.
