3.√(27x^9) = (27x^9)^(1/3) = 3x^3
(-3, 1.5)....simply add the x coordinates together, divide them by two, and then do the same for the y coordinates.
Solution
Find the y-intercept for following equation:

Using the slope equation formular:

The value of y when x = 0

Hence the answer is - 1
Answer\
X is 84 ;)
Step-by-step explanation:
We have that
smaller figure
ha=8.7
ra=1.6
larger figure
hb=10.44
rb=1.92
ha/hb=8.7/10.44----> 0.83
ra/rb=1.6/1.92-------> 0.83
ratio smaller figure to the larger figure
1.6/1.92-------> divided by 1.6 both members[1.6/1.6]/[1.92/1.6]-------> 1/1.2
the ratio ha/hb is equal to the ratio ra/rb
so
the smaller figure and the larger figure are similar
and
the ratio smaller figure to the larger figure is equal to----> 1/1.2
the answer is
the option yes 1/1.2
