Step-by-step explanation:
a,a, and a
Since this is a piecewise function, we will want to find the right equation to use. We want to find f(2) so we will find the equation to use when x=2. This will be the third equation because it is -2<=x<=2. We then plug 2 into x^2 -2. This will give us (2^2)-2 = 4-2 = 2.
Answer:
251 miles on Tuesday
Step-by-step explanation:
327 miles + n miles = 578 miles (total).
Solving this for n, we subtract 327 miles from both sides, obtaining:
n = 251 mi = distance Danny traveled on Tuesday
Multiply the second row by -1 to cancel out the 7x.
9x+7y=10
-7x-7y=-14
2x=-4
x=-2
9(-2)+7y=10
-18+7y=10
7y=28
y=4
