We put cubic feet of water used on the x-axis and the cost on the y-axis.
The graph will start at (0 , 12.7) because this is the fees before using any water.
The slope of the graph from 0 < x < 300 will be $0.039/cubic ft, and this interval will start at (0 , 12.7) and end at (300 , 24.4).
The slope of the graph for x > 300 will be $0.052/cubic ft, and this interval will start at (300 , 24.4) and continue to x value infinity.
220 units lies within the interval 0 < x < 300 so we use the first slope.
y = 0.039(220) + 12.57
= $21.15
We break 675 cubic feet into two parts, 300 + 375 cubic feet as they will be charged differently.
The cost of the first 300 cubic feet = $24.40
The cost of the remaining 375 cubic feet = 0.052 x 375 = $19.50
Total cost of 675 cubic feet = $43.90
Answer:
-2
Step-by-step explanation:
This linear equation is in slope-intercept format, aka y=mx+b. This is where m=slope and b=y-intercept. In the following equation, -110 is the slope and -2 replaces b, meaning it is the y-intercept
Answer:
$41 250
Step-by-step explanation:
15% * $275 000 = $41 250
Answer:

Step-by-step explanation:
3rd side = x
Answer:A perpendicular bisector is a line that cuts a line segment connected by two points exactly in half by a 90 degree angle. To find the perpendicular bisector of two points, all you need to do is find their midpoint and negative reciprocal, and plug these answers into the equation for a line in slope-intercept form.
