Answer: The submarine was 245 feet below sea level after 9 minutes.
Step-by-step explanation: Since y represents minutes, replace it with 9...
-380 + 15(9)
-380 + 135
-245
Since it’s negative, the submarine is still below sea level.
Answer:
5 1/4
Step-by-step explanation:
Subtracting a negative is the same as adding a positive.
2 3/8 - (-2 7/8) =
= 2 3/8 + 2 7/8
= 4 10/8
= 4 + 8/8 + 2/8
= 4 + 1 + 1/4
= 5 1/4
Ok so from experience on this site
3x2=3x^2
people don't know how to put exponents
3x^2-y^3-y^3-z
simplify first
3x^2-2y^3-z
x=3
y=-2
z=-5
3(3^2)-2(-2)^3-(-5)
3(9)-2(-8)+5
27+16+5
48
