Answer:
Step-by-step explanation:
The gradient of a line is the coefficient of x when the equation of the line is written in the form of y=mx+c.
Thus, gradient of given line=.
The product of the gradients of perpendicular lines is -1.
(Gradient of line)(-3/2)= -1
Gradient of line
Substitute m= into y=mx+c:
To find the value of c, substitute a pair of coordinates.
When x= -6, y= 8,
Thus, the equation of the line is .
Answer:
h(7) = 29
h'(7) = 44
Step-by-step explanation:
If , to find h(7) we can substitute the values of f(7) and g(7) and we get:
To find the derivative, we know that the derivative of a sum of functions equals the sum of the derivatives of those functions.
This would mean that , we can substitute the values for f'(7) and g'(7)
