Answer:
9
Step-by-step explanation:
The rate of change of a function f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ 3, 7 ]
f(b) = f(7) = 47 and f(a) = f(3) = 11, hence
rate of change = =
= 9

Answer:
The value of x for the expression is 2
Step-by-step explanation:
Given algebraic expression as :
(4 + 6 x ) =
x +
( x + 9 )
Now, solving the given expression
Or, × 4 +
× 6 x =
x +
x +
× 9
Or, +
× x =
x +
x +
or, 2 + 3 × x = +
+ 6
or, 2 + 3 × x = + 6
or, 2 + 3 × x = + 6
Or, 2 + 3 × x = x + 6
or, 3 x - x = 6 - 2
Or, 2 x = 4
∴ x =
I.e x = 2
Hence The value of x for the expression is 2 Answer
