The 5's in 4,557 are 500 and 50.
Answer:
Step-by-step explanation:
1) Let a=1, b=2. Therefore we have two pair of points (1,0) and (0,2) since a must be on x-axis and b on y axis.
Equation of the line: 
2) Since 2 is the point on the y-axis, then b=2 we can say that
Answer:
Infinite solutions.
Step-by-step explanation:
-4x = y + 3......(1)
y = -4x - 3........(2)
Rearranging equation (1)
y = -4x - 3 ------(3)
Adding (2) and (3) we get
0 = 0.
The original equations are identical and their graph will be the same straight line.
Any point on the line is a solution of this system, so there are infinite solution.
You don't want 'x' in the polar form. The arguments
of the sin and cos should be angles.
You're doing great. You're already through the tough part.
You knew that x = r cos(α) and y = r sin(α) .
The correct equation for where you stopped is
x· y = r² · cos(α) · sin(α) = 1
You can simplify it a little if you remember the 'double-angle' equation:
sin(2α) = 2 · sin(α) · cos(α)
So cos(α) · sin(α) = (1/2) sin(2α)
and r² · cos(α) · sin(α) = 1
r² · sin(2α) = 2
Answer:
6
Step-by-step explanation:
Given: (5,-9) is on the graph of f(x)
To find: corresponding point for the function 
f(x)
Solution:
A graph refers to a pictorial representation that represents the relationship between two or more things in an organised manner. It consists of two axes x-axis and y-axis perpendicular to each other at the origin.
As (5,-9) is on the graph of f(x),
So,
