Step-by-step explanation: The base of the power in the original equation becomes the base of the log. So we have 
.
Next, the exponent in the original equation goes on the other side of the equation and finally, the result in the
original equation goes inside the log.
So we have 
which is 7³ = 343 written in logarithmic form.
Answer:
to be honest i need the points so srry
Step-by-step explanation:
2x(x-3) - 3x (4x-1)
First I like to change subtraction to addition of the opposite.
2x(x+ -3) + -3x (4x + - 1)
Now distribute
2x^2 + -6x + -12^2 + 3x
Now combine everything
-10x^2 - 3x
3x+y=9.....i
3x-5y=15...ii
subtracting ii from i we get
6y=-6 so y=-1
x=10/3
