just be sure our final answer would be A=-b/2x?

yeah your final answer would be a=-b/2x because it cant be simplified or solved further

Using Models Use the model given to answer the questions about the object or process being modeled. An ocean diver models the pressure $P$ ( in $\mathrm{lb} / \mathrm{in}^{2} )$ ) at depth $d$ (in ft) by $$P=14.7+0.45 d$$ (a) Make a table that gives the pressure for each 10 -ft change in depth, from a depth of 0 ft to 60 $\mathrm{ft}$ . (b) If the pressure is $30 \mathrm{lb} / \mathrm{in}^{2},$ what is the depth?

Using Models Use the model given to answer the questions about the object or process being modeled. The portion of a floating iceberg that is below the water sur- face is much larger than the portion above the surface. The total volume $V$ of an iceberg is modeled by $$V=9.5 S$$ where $S$ is the volume showing above the surface. (a) Find the total volume of an iceberg if the volume show- ing above the surface is 4 $\mathrm{km}^{3}$ . (b) Find the volume showing above the surface for an ice- berg with total volume 19 $\mathrm{km}^{3}$ .

we're gonna look at X equals negative B over two A. And we're gonna solve for a now because A is in the denominator I want to rewrite. The first step is I'm gonna rewrite this equation to where I no longer have a fraction. So I'm going to do that by multiplying both sides by the denominator. And I know the A is in the denominator, and that's okay. We just want to remove it as a fraction. So we're gonna multiply both sides by two A. So that means on the left side. Now I have to a X equals the denominator is going to cancel out on the right and leave me with just negative b. So now let's look at the left side. Now that I've done that, I can see on the left side what I really have is two times a times X equals negative bay. So that means that the two and the X are both being multiplied by the A. So in order to move on, we need to do the opposite of multiplication. And the opposite of multiplication is always going to be division. So we're going to divide both sides by two X So that's gonna cancel them out on the left side and leave me with just a equals negative B over to X.
