(1, 5) and (-3, 9)
Step-by-step explanation:
6 pairs of shoes and 40 hats
So basically you just want to isolate the variable. So you want n on a side all by itself. so first you multiply by -2 to both sides, that will leave you with the equation n+4=18, then you subtract 4 from both sides, this will give you the equation n=14. To make sure this solution is correct, you can plug it back into the equation filling 14 in for n, this equation is 14+4/-2=-9, and this solution works. Hope this helped :)
C. 1/2x-10 _>0
can be ued to find the domin of f(x)
Distribute
18-8+15=13
combine like terms
10+15=13
