Answer:
the third one and the last one is correct
Step-by-step explanation:
we already know the second one is wrong because of it's set up.
just replace the points (-1,7) into each equation. if it doesn't work then move on to the next one. if it does work, then use that same equation except this time to the coordinates (2,4)
Answer:
z = -ln│5eᵗ + C│
Step-by-step explanation:
dz/dt + 5eᵗ⁺ᶻ = 0
dz/dt = -5eᵗ⁺ᶻ
dz/dt = -5eᵗeᶻ
-e⁻ᶻ dz = 5eᵗ dt
e⁻ᶻ = 5eᵗ + C
-z = ln│5eᵗ + C│
z = -ln│5eᵗ + C│
Answer:
I put all the steps down. I don't know which one you want. I hope you understand it now.
Step-by-step explanation:
b = baking time
p = preperation time
p = 1/3b
12 = 1/3b
b = 12*3
b = 36 minutes
Answer:
-16j²k
Step-by-step explanation:
Answer:
June has 7 green and 28 blue marbles
Step-by-step explanation:
b + g = 35
b = 4g
Use substitution method to solve them simultaneously
4g + g = 35
5g = 35
g = 7
b = 4g = 4(7) = 28
b = 28, g = 7
She has 7 green and 28 blue marbles
