Answer:
someone please answer
Step-by-step explanation:
I need this too
1 is x=13.5
2 is x=-260
3 is x=38
4 is x=-37^38
i think this is correct
Answer:
x=-2
Step-by-step explanation:
(2/3)^x-1=27/8
Rewriting the right hand side
(2/3)^x-1=(3/2)^3
We know that a^-b = 1/a^b Hint: { 1/(3/2) = 2/3}
(2/3)^x-1=(2/3) ^-3
The bases are the same, so the exponents are the same
x-1 = -3
x -1+1 = -3+1
x = -2
m + 4 = 5m - 12
Subtract m from both sides.
4 = 4m - 12
Add 12 to both sides
16 = 4m
Divide both sides by 4
m = 4
