cant help when you put question marks!
please do this better!
Answer:
Step-by-step explanation:
The first thing that we can do is look at the equation of the line and then worry about the inequality afterwards.
This line has a y-intercept of 4 and a slope of -1.
This means that the equation of this line would be 
Now that we have the equation of the line, we just need to determine which inequality sign to use.
As the shaded region is BELOW the line, we will use a less than (<) sign.
As the line is fully shaded, I can only assume that it is meant to include the line, which would mean that would be the equation for this inequality.
Recall that the y-intercept is when the function passes the y-axis. This happens when x=0. Therefore, we can find our y-intercept by plugging x=0 into our function and solving for y.
6x + 9y = 18
6(0) + 9y = 18
0 + 9y = 18
9y = 18
y =2
Thus, our y-intercept is when x = 0 and y = 2, or (0,2).
The number of cubes that Devin will need to make will be given by:
(volume of each pyramid wax)/volume of cube
volume of cube=length*width*height
=4×4×4
=64 cm³
volume of the candle=1/3π*(base area)*h
=1/3×(9×9)×10
=270 cm³
number of cubes needed
270/64
=4.21875~4.23 cubes
No its not a proportional relationship because there is too much of the equation on one side if it was y=4x then it would be proportional. Hope that helped.
