True. When the points are plotted on a graph and connected, they pass the vertical line test. No x value is the same.
So a 3 foot cable is10.25
a 6foot cable is 15.50
so
x=cost per foot
y=cost of special connectors
3x+y=10.25
6x+y=15.50
make first equation negative and add to the first
3x=5.25
divide both sides by 3
1.75=x
so it costs 1.75 for a foot of cable
subtitue into first equation
3(1.75)+y=10.25
5.25+y=10.25
subtract 5.25 from both sides
y=5 dollars=cost of special so
4x+y=4(1.75)+5=7+5=$12
so the cost of a 4 foot cable is $12
X= -11.14
y= -18.14
Plug in and check for yourself but these answers worked for me.
<h3>Answer:</h3>
We know that,
Volume of cone = 1/3πr²h
- 1/3 × π × (7)² × 9
- 49 × 3π
- 147π inches³
So. <u>Correct choice</u> - [B] 147π inches³
Answer:
V = 3216.9 
Step-by-step explanation:
Volume of a cylinder = π 
h
We are given diameter, 16cm, and half of it is the radius
r = 8cm
h = 19cm
Substitute the values into the equation
V = π * 
* 19
V = 3216.9
