Answer:
B) x^2 - 3/ 3x
Step-by-step explanation:
As, f(x) - g(x) = x/3 - 1/x
So, x^2/ 3x - 3/ 3x
= x^2 - 3/ 3x
Answer:
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Parallel lines have the same gradient. Hence the gradient of line r is 
.
Susbt. m=,
To find c, substitute a coordinate.
When x=3, y= -9,
-9= 1 +c
c= -9-1
c= -10
Thus the equation of line r is .
Answer:
They have the same y-intercept.
Step-by-step explanation:
The y-intercept occurs when x = 0 so for f(x):
y-intercept = f(0) = -6(0) - 3 = -3.
For h(x):
y-intercept = h(0) = 2 cos(0 + pi) - 1
= 2 cos pi - 1
= 2 *-1 - 1 = -3.
