How does an indirect proof differ from a regular proof?
a. an indirect proof switches the order of the left and right columns
of a regular proof.
o
b. an indirect proof begins by assuming that the opposite of what
you are trying to prove is true.
o
c. an indirect proof uses three columns
o
d. an indirect proof does not back up statements with a
corresponding reason.

 B.

Step-by-step explanation:

I'm basing my answer on the fact of definitions.

DIRECT PROOF:

A direct proof assumes that the hypothesis of a conjecture is true, then uses logical deductions to prove why its conclusion is true

INDIRECT PROOF:

An indirect proof relies on contradictions to prove a given conjecture, it assumes the conjecture is wrong until it runs into a contradiction that proves it as true.

Based on this

B. An indirect proof begins by assuming that the opposite of what you are trying to prove is true.

You can be the judge this is what I would pick

Good luck I hope you pass  

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
