Write the word sentence as an inequality . a number b minus 4.2 is less than - 7.5 . what is the inequality

b-4.2<-7.5

Step-by-step explanation:

if you need an answer to the inequality then it is b<-3.3

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.
