Y=.5(1.06)exponent x where x=10, 20, 30 and 50

#1.) x = -4

Step-by-step explanation:

for #1 do distributive property. if you have -3(x-5) distribute -3 to both of them. you should get -3x+15=27. subtract 15 from both sides canceling out on the -3x side and giving you -3x=12 on the other side. now divide -3 from both sides giving you -4 and leaving x by itself.
