There isn't enough information to know the exact number of b but
w=2a+3b
subtract 2a from both sides
2a-w=3b
divide both sides by 3
w=2a+3b
subtract 2a from both sides
2a-w=3b
divide both sides by 3
Answer:
.
Step-by-step explanation:
A line that goes through and
where
would have a slope of
.
The slope of the line that goes through and
would thus be:
.
Two lines in a cartesian plane are perpendicular to one another if and only if the product of their slopes is .
Thus, if and
denote the slope of the first and second lines in this question,
since the two lines are perpendicular to one another. Since
, the slope of the first line would be:
.
Given that the first line goes through the point , the point-slope equation of that line would be:
.
.
Substitute in to find the
-coordinate of the point in question:
.
Answer:
Step-by-step explanation:
Given: A town's population has been growing linearly. In 2003, the population was 35000, and the population has been growing by 1200 (constant rate of change) people each year.
The equation of a line is given by :-
, where m is the slope ( constant rate of change) and c is the initial value of the function.
From the given statement , we have the equation for the population x years after 2003 :-
