There are several important information's already given in the question. Based on those given information's the answer can be easily deduced.
Ratio of the radii of two spheres = 9 : 2
then
Ratio of the volume of the two spheres = 9^3 : 2^3
= 729 : 8
I hope that this is the answer that you were looking for and the answer has actually come to your desired help.
Rearrange the equation so the left side starts out as y =
5x + 3y = -4
3y = -5x - 4
y = (-5/3)x - (4/3)
the slope is in front of the x and the y-intercept iis the other number
slope is -5/3
y-interxept = -4/3
Answer:
<h3>
2x+11</h3>
Step-by-step explanation:

Add similar elements :6x-4x=2x
Add Subtract the numbers :12-1=11

m = 1.49
b = 5.50
equation y = 1.49x + 5.50
Non-proportional
Positive Slope
