for the first one set 3y+y=180 and y+x=180
the second one set w+y=180, 42+x=180, y+20=180, and 87+v
Vertical asymptotes ares found where the function is undefined. f(x) is undefined when the denominator equals zero:
x^2-1=0
<em>*Add 1 to both sides*</em>
x^2=1
<em>*Take the square root of both sides*</em>
x=+/-1
There are vertical asymptotes at x=-1 and x=1.
Hope this helps!!
Answer:
4 days
Step-by-step explanation:
If he consumed 6 liters in two days, that would mean he would have consumed 3 liters per day. You would divide 12 by 3, since he drinks 3 liters per day, and after 4 days, he would have consumed 12 liters.
The answer is D because all you have to do is subtract the two numbers in the water tank.
