- Consider f(x) = 7x3 - 15x2 - 19x +3. Find the solutions of each of the following equations!
(a) f(x) = 0
(b) f(x-1)= 0
(c) f(x + 2) = 0
(d) f(2x)= 0

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

the answer

b. they are parallel and will never intersect.
