Question

Help me with both questions
plz read carefully so you can help me

Answer 1

1. both are correct

2.f=5 g=-2 e=-3

Explanation:

for number two, because e is negative you can logically figure out that f is positive and g is negative because a negative times a negative is a positive and a negative times a positive is a negative. you are then left with

-e times f=

-e times -g=

f times -g=

then by the process of substitution and trial and error, you can logically conclude that f=5 g=-2 e=-3

Answer 2

2. Both

3. e = 3, f = -5, g = 2

Explanation:

2. Order doesn't affect product

3. You get e • f = -15, e • g = 6, f • g = -10 from the problem.

e = -15/f (solve for e)

(-15/f) • g = 6 (plug into second equation)

(-15g/f) = 6 (multiply)

-15g = 6f (multiply)

(-5g/2) = f (divide)

(-5g/2) • g = -10 (plug into last equation)

(-5g^2)/2 = -10 (multiply)

-5g^2 = -20 (mulitply)

g^2 = 4 (divide)

g = 2 (square root)

e • g = 6 (plug in for g, solve for e)

e • 2 = 6

e = 3

f • g = -10 (plug in for g, solve for f)

f • 2 = -10

f = -5

I don't know if your teacher made a typo because I tried this multiple times and got the same answer. I don't know how e is negative.
