Renting a surf board at Sally's Surf Shack costs $3 per hour plus a one time fee of $4. Renting a surf board at Selling Surf Stuff costs
$5 per hour with no additional fee. The hourly cost to rent a surf
board depends on the number of hours, h, it is rented for. Which
inequality represents the situation when the hourly cost at Sally's Surf
Shack is less than the hourly cost at Selling Surf Stuff?
a) 3h+4<5h
b) 3h+4>5h
c) 3+4h<5h
d) 3+4h>5h

hello,

elba writes the following proof for the theorem: if the diagonals of a quadrilateral bisect each other, the quadrilateral is a parallelogram:

elba's proof

1. for triangles aob and cod, angle 1 is equal to angle 2 as they are vertical angles.

2. ao = oc and bo = od because it is given that diagonals bisect each other.

3. therefore, the triangles aob and cod are congruent by sas postulate.

4. similarly, triangles aod and cob are congruent.

5. by cpctc, angle abd is equal to angle cdb and angle adb is equal to angle cbd.

6. as the are congruent, the opposite sides of quadrilateral abcd are parallel.

7. therefore, abcd is a parallelogram.

which is the missing phrase in elba's proof?

answer - opposite
