Answer:
<h2>f^-1(x) = x/2 -1 </h2>
Step-by-step explanation:
Let y equal to the given equation ;
Solve for x ;
Change the y back to x
Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to determine that RQ² + PR² = PQ².
<h3>What is Pythagorean theorem?</h3>
Pythagorean theorem is a mathematical expression in Euclidean geometry that can be used to solve for any of the three (3) side lengths of a right triangle.
Mathematically, Pythagorean's theorem is given by this formula:
x² + y² = z²
Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to determine that RQ² + PR² = PQ². It is given that x² + y² = z² in triangle ABC, so z² = PQ² or AB = PQ.
The above information shows that the triangles are congruent because their three (3) sides are congruent. Therefore, to show that triangle PQR is a right triangle, we can use corresponding parts of the congruent triangles to show that PQ = AB, PR = AC and QR = BC.

Answer:
Step-by-step explanation:
slope of line perpendicular to y=mx+c is -1/m
so here reqd. slope=-1/4
Let S be the set of whole numbers between 3 and 15 then <span>S={3,4,5,6,7,8,9,10,11,12,13,14,15}</span> so How many elements are in the set ? just count them..
Order the numbers smallest to largest and go to the middle, the middle number is your answer :)
