Given:
a varies jointly as b and c.
a=6 when b=2 and a=3.
To find:
The variation constant and the equation of variation.
Solution:
a varies jointly as b and c.
...(i)
Where, k is the constant of proportionality.
a=6 when b=2 and a=3.
The value of k is 1.
Putting k=1 in (i), we get
Therefore, the variation constant is 1 and the equation of variation is .
The answer is D.
First solve for y.
You end up with:
y=-1/2x+3/2
Because they want a parallel line, the slope stays the same.
Our equation will look like
y=-1/2x+b
Now plug in the given coordinates
4=-1/2(6) + b
4=-3+b
b=7
Therefore, the equation of the line is
y = -1/2x + 7
Answer:
how do u want to transform that-
Step-by-step explanation:
We only need to know 2 points so let's take the first 2.
slope formula
y2 - y1 over x2 - x1
3000 - 2500 over 10000
The slope is .05. To find the y intercept go left 10,000 and down 10,000 x .05.
The answer is C
