Please help me with this homework

answer is |-1| < 7

{-1}<7 Hope it helped brainiest plz

Step-by-step explanation:

7 is greater than {-1} because it's a negative number and 7 is a positive.

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.

5x+2x=49

7x=49

x=7. 35 apples
