What are the solution intervals for |x + 6| > 10? Options: A) x < –16 or x > 4 B) x < 16 or x > –4 C) x > –16 or x < 4 D) x > 16 or x < –4
so split it into two x+6=10 x+6=-10 and solve for x
x=4 x=-16
@ninab731 ???
yes :)
wats the answer then?
is it A or C??? @ninab731
plug into the equation both -15 and -17 what are your results?
wat?
if u plug into your original equation |-15+6|>10 what do u get and then also plug in -17
-9>10 -11>10
its positive because of absolute value so should be 9>10 or 11>10 so your answer based off of this is A
What I would suggest for you to do is to substitute the numbers for x. However, do the numbers that are eventually applicable to the way that they are put. For example, if we want to see if A is correct, then what we can do is find a number that is less than -16 and a number that is more than 4. Test it out to see if it goes with the interval equation.
But first what number gives you 10 when added to 6?
