X = -6y - 12
4x + 5y =-39
4x + 5y = -39
-4(-6y - 12) + 5y = -39
-4(-6y) + 4(12) + 5y = -39
24y + 48 + 5y = -39
29y + 48 = -39
29y = -87
y = -3
x = -6y - 12
x = -6(-3) - 12
x = 28 - 12
x = 6
(x, y) = (6, -3)
Answer:
8
Step-by-step explanation:
One foot = 12 inches.
32 feet = x inches
x/12=32/1
so
x=12*32/1 inches per second^2
Answer:
h'(1)=0
Step-by-step explanation:
We use the definition of the derivative of a quotient:
If
, then:

Since in our case we want the derivative of
at the point x = 1, which is indicated by: h'(1), we need to evaluate the previous expression at x = 1, that is:

which, by replacing with the given numerical values:

becomes:
