Answer:
Step-by-step explanation:
p(x) = |x|
in : R let : y = |x|
calculate : x
y² = |x| ²
y² = x²
y² - x²= ( y - x)( y +x) by identity
y = x or y = - x
the inverse : y = x or y = - x
conclusion : the inverse is : g(x) = |x|
Answer:
65 miles
Step-by-step explanation:
There are two simultaneous equations
. Remeber that v=d/t, 1hour = 60 minutes.
1. 40 = (d+15)/(t+0.5)
2. 50 = d/t
solving: d= 25 miles and t=0.5 hours.
The distance traveled is:
D=d+d+15
D=65 miles
There are 4 quarts in 1 gallon.
3 x 4 = 12
12 + 2 = 14 quarts
