Y = -9x - 10
The dolphin is diving 9 feet per second so the rate of change is -9.
It's also 10 feet below sea level which makes the y-intercept -10
Hope this helped!
Answer:
x = 2, y = -3
Step-by-step explanation:
Add them together and get
9x + 8y - 9x - 9y = -6 + 9
-y = 3
so y = -3.
Sub it into the first equation and get
9x + 8(-3) = -6
9x - 24 = -6
9x = -6 + 24 = 18
x = 18/9 = 2

I have the same question and I'm looking for the answer
Answer:
A=x(32-x)
Step-by-step explanation:
for a 32ft divider, e need to determine the length of the sides of the rectangular space. but since the length and breadth gives 32ft, we can express the side as
breadth= b,
length=x
x+b=32
b=32-x,
hence the area can be expressed as
A=l*x
A=x(32-x) unit square
the area expressed as a function of x is giving below
A(x)=x|(32-x)
