Answer:
3x - y = 7
Step-by-step explanation:
point slope form: y= mx + b
standard form: ax + by= c
y= 3x - 7
- subtract 3x from each side
-3x + y = -7
- because "a" in the standard for equation can not be a negative number, multiple each side by -1
3x - y = 7
Form of direct variation looks like y = kx, where k is any constant number (2, 3/4, 1/3, etc)
So here you have xy = 5.
Divide both sides by x, and you have y = 5/x.
So it is not direct variable, it is inverse variation.
Answer:
36
Step-by-step explanation:
plug in a=3 for a
I belive you meant 99- 7 * a^2
so 99- 7 * (3)^2 = 36
