Answer:
3^-x= 3^ 3x + 6
Step-by-step explanation:
match bases
remeber if a^b=a^c where a=a then b=c
remember
(x^m)^n=x^(mn)
1/(x^m)=x^-m
base of 3
(1/3)^x=(3^-1)^x=3^(-x)
27^(x+2)=(3^3)^(x+2)=3^(3x+6)
3^(-x)=3^(3x+6)
-x=3x+6
0=4x+6
-6=4x
-3/2=x
Answer:
B is your answer
Step-by-step explanation:
(50.40 + 309.60) divided by 144 = 2.50
First you'll need to get the same denominator. So instead of 3/5 and 3/8 you'll have 24/40 and 15/40. Now that we've changed the value of the denominator, the 40/40 will now represents the 1 hour that Jenny has before bedtime. So you add 24/40 and 15/40 and get 39/40. 39/40 stands for the time that Jenny has already spent brushing her teeth and texting her friend all together. Since the 1 hour is 40/40 subtract 39/40 from it to get 1/40. 1/40 is equal to the rest of the time Jenny spends reading or 1.5 minutes.
Center of the circle is (5; -5)
