Z + 3z + 1 + 204 + 54 = 360
4z + 259 = 360
4z = 360 - 259
4z = 101
z = 101/4
z = 25.25 °
Answer:
f = 4d -400
Step-by-step explanation:
First, let's make some variables.
f = size of Falls Lake
d = size of Lake Drummond
d = (1/4)*f + 100
We can now rearrange the equation to find the size of Falls Lake.
d - 100 = (1/4)*f
4d - 400 = f
f = 4d - 400
The graph represents a function.
You can tell if a graph is function or not by using the vertical line test.
If the line only passes one point of the y-axe, it is a function. But when the graph passes more than two points, it is not a function.
