Step-by-step explanation:
Given an expression that represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute is as follows :
-320+15y
We need to find the depth of submarine after 15 minutes.
Put y = 15 in the above expression.
-320+15y = -320+15(15)
= -320 + 225
= -95
Hence, the submarine is below sea level at 95 feet.
Answer: (x−3)(x+7)
=(x+−3)(x+7)
=(x)(x)+(x)(7)+(−3)(x)+(−3)(7)
=x^2+7x−3x−21
=x^2+4x−21

Answer:
3/4 or 0.75 decimal
Step-by-step explanation:
Simplify the following:
(2/3)/(8/9)
Hint: | Write (2/3)/(8/9) as a single fraction.
Multiply the numerator by the reciprocal of the denominator, (2/3)/(8/9) = 2/3×9/8:
(2×9)/(3×8)
Hint: | In (2×9)/(3×8), divide 9 in the numerator by 3 in the denominator.
9/3 = (3×3)/3 = 3:
(2×3)/8
Hint: | In (2×3)/8, divide 8 in the denominator by 2 in the numerator.
2/8 = 2/(2×4) = 1/4:
Answer: 3/4
