The point at 1/3 of XY
If the point is at 1/3 for X, then the other end (to Y) is 2/3
So, we have:

Multiply by 3

The point (P) is calculated using:

This gives:

Answer:
20 and 90
Step-by-step explanation:
F(x) = x² -3x +(3/2)² -10 -(3/2)²
= (x -3/2)² -10 -9/4
f(x) = (x -1.5)² -12.25
The answer is: "- 4 " .

Explanation:
________________________________________
Given: " f(x) = 1 – 5x " ; Find: " f(1) " ;
Substitute "1" for values of "x" ;
→ f(1) = 1 – 5(1) = 1 – 5 = - 4 .
The answer is: "- 4 " .
