Answer:
810
Step-by-step explanation:
The original price of the car = 100%.
Price is decreased by 10%- price now equal 90% of original.
Let original price = x
.9x=729
x=810
Check:
810 - .1(810) = 729
True!
Answer:
Step-by-step explanation:
i am not sure how to do this one but i am sure that if you look it up on google you'll fund the answer. Just saying.
The reflection over the x-axis is given by the transformation:
f₁(x) = - f(x)
Therefore, the first step is:
f₁(x) = - log(4x)
Stretching by a factor n along the y-axis is given by the transformation:
f₂(x) = n · f₁(x)
Therefore we get:
f₂(x) = -3 · log(4x)
Shifting a function down of a quantity n is given by:
f₃(x) = f₂(x) - n
Therefore:
f₃(x) = -3·log(4x) - 2
Hence, the correct answer is C) g(x) = <span>-3·log(4x) - 2</span>
