You reverse the inequality symbol if you divide or multiply by a negative number in order to solve the inequality.
Answer:
The answer is C)5q⁶r⁸
Step-by-step explanation:
Hope this helps
x^2 - 3x -28 ≥ 0
factor
(x-7) (x+4) ≥ 0
x=7 x=-4
we have three regions where the answers can lie
x<-4 between -4 and 7 and x>7
pick a point and see if it works
x=-10
(-10-7) (-10+4) ≥ 0
negative * negative is greater than 0 so this is a solution x< -4
x=0
(0-7) (+4) ≥ 0
negative * positive is less than 0 so this is not a solution
x=10
(10-7) (10+4) ≥ 0
positive * positive is greater than 0 so this is a solution x>7
We have two regions that work
x<-4 and x>7
Answer:
Step-by-step explanation:
When two lines cross into any kind of x shape , four angles are made. if you look at one angle, there are two on either side. These are NOT vertical angles. The third angles though is vertical from the starting angle.
