To solve this, simply switch the X and y variables within one equation, and upon doing so, see and check if it equals to the other equation.
f(X) = -X + 4/5
Y = -X + 4/5
X = (-Y+4)/5
5X = -Y + 4
-Y = 5X - 4
Y = -5x + 4
Yes, by looking at the second equation it is an inverse of the first one.

Answer:

Step-by-step explanation:
First find the <em>rate of change</em> [<em>slope</em>]:


Then plug these coordinates into the Slope-Intercept Formula instead of the <em>Point-Slope Formula</em> because you get it done much swiftly. It does not matter which ordered pair you choose:
−7 = −2[4] + b
−8

If you want it in <em>Standard Form</em>:
y = −2x + 1
+2x + 2x
_________

_______________________________________________
5 = [−2]² + b
4

y = −2x + 1
+2x + 2x
_________

** You see? I told you it did not matter which ordered pair you choose because you will always get the exact same result.

Step-by-step explanation:
Using cosine rule,
f² = g² + e² - 2(g)(e)(cosF) = 6.7² + 5.9² - 2(6.7)(5.9)(cos70°)
= 52.6598 in²
Hence f = 7.3 in.
