It depends, what does a mean? If you know just add what a means to 3 then subtract 4.
Answer:
Step-by-step explanation:
<h2>Equation of line in slope y-intercept form:</h2>
![\sf y - [-3] = \dfrac{1}{2}(x - 2)\\\\y + 3 = \dfrac{1}{2}x - 2*\dfrac{1}{2}\\\\y + 3 = \dfrac{1}{2}x-1\\\\](https://tex.z-dn.net/?f=%5Csf%20y%20-%20%5B-3%5D%20%3D%20%5Cdfrac%7B1%7D%7B2%7D%28x%20-%202%29%5C%5C%5C%5Cy%20%2B%203%20%3D%20%20%5Cdfrac%7B1%7D%7B2%7Dx%20-%202%2A%5Cdfrac%7B1%7D%7B2%7D%5C%5C%5C%5Cy%20%2B%203%20%3D%20%5Cdfrac%7B1%7D%7B2%7Dx-1%5C%5C%5C%5C)
Answer:
Ex1. X=-1
Ex2. 3rd choice
Step-by-step explanation:
Ex1. The only discontinuity in the domain is x=-1
Ex2. You just add values of x to those options and see which one applies
V=l*w*h
V= 15*8*3
V= 120*3
V= 360
The pool will hold 360 cubic meters.
