Answer:
The distance between Shawna's Home and Rochester is 228 mi and takes her 6 hr to make the drive.
Step-by-step explanation:
<u>Known Data</u>
Final distance is the same for both , but for Terrence , due he didn't arrive for 56 mi
Initial distance is the same for both
Shawna's Velocity , and time
Terrence's Velocity , and time, as he starts 2hr later
<u>Formula</u>
, for both cases
<u>Equation System</u>
Shawna: or (1)
Terrence: , , and finally (2)
By solving this equation system (1) and (2), using any method, we obtain and .
h(x) = x + 7/4
Replace h(x) with y
y = x + 7/4
Swap x and y
x = y + 7/4
Solve for y.
Subtract 7/4 from both sides.
y = x - 7/4
Replace y with h(x)^-1
<h3>h(x)^-1 = x - 7/4</h3>
The answer would be 3 & -3 because
-3 |-3| and 3 |3|
Pretty sure it’s going to be D.
