Evaluate t - u/v when t =3 u = -8 and v = -1/2 in a big test

that will be 3-8/1/2 or 3-8/-.5

simplify 8/0.5 and get- 16

3--16 you kcc (kepp change change)

and get 3+16 and u add them

then u should get 19 as your answer.

your welcome

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.
