3y=x and x+y=180
So you need to put 3y in for x, that gives you (3y)+y=180 or 4y=180. Then you divide 180 by 4 to get y=45 aces. After that you plug 45 in for y, 3(45)=x. This gives you x=135 aces.
Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept)
Answer:
f(x) = -x -3
Step-by-step explanation:
Answer: 3.5a+5b=470 and a+b=115
Step-by-step explanation:
For this case we have to define "y" directly with "x" when there is a constant of proportionality "k", such that:
This is known as direct variation.
On the other hand, if y varies inversely with x we have to:
This is known as inverse variation.
Answer:
, direct variation
