Hopefully this helped! I used the substitution method
Given:
The three equations for the three numbers are
To find:
The Pythagorean triple generated by using 4 for x and 1 for y.
Solution:
Substituting x=4 and and y=1 in the given equations, we get
In the same way find b and c.
The third number is
The required Pythagorean triple is 8, 15, and 17.
Therefore, the correct option is C.
Answer is (A) x < 14/5
(B) x < -21/4

-4x=-x2+12 should be written <span>-4x=-x^2+12, with " ^ " representing exponentiation.
You are to invent a table of x values and find the difference between -4x and -x^ 2+12. The smaller the difference, the closer you are to finding the correct root, x.
To get you started:
x -4x x^2+12 difference
--- ------------ ---------------- --------------
2 -8 16 24 (pretty bad!)
-4 16 28 12 (better)
-10 40 112 72 (much worse)
To answer this problem correctly, you must present such a table, even tho' it'd be faster to use the quadratic formula (or some other method) to find x.
