Answer:
$0.25 per ounce
Step-by-step explanation:
3.75 divided by 15 is 0.25
So here, I would first multiply 0.17777.... (Assume that that's x) by 10, then you get
10x = 1.777777...
And then subtract x from 10x and then you get 1.6.
So that means that
10x - x = 9x
and 1.7777... - 0.17777... = 1.6
So now to solve for x, divide both sides by 9
To get 1.6/9 = x
Or 16/90 = x
Or 8/45 = x
(That explanation made no sense)
At f(-3) the graph is equal to -9.
In order to find the point on the graph, move over to -3 on the x axis. Then move down to find the point where it hits the parabola. You'll see that the parabola hits at point (-3, -9).
Use the formula of a distance between two points:


Answer:
y = -1/13x + 1 3/13
Step-by-step explanation:
y = 13x + 2
Perpendicular
y = -1/13x + b
Finding b:
1 = -1/13 * 3 + b
1 = -3/13 + b
1 3/13 = b
y = -1/13x + 1 3/13
