Answer:
6
Step-by-step explanation:
Add all the numbers together and divide by the amount of numbers
6+9+3+8+9+3+4= 42
42/7 = 6
The slope equation is
y = mx + b
We already know m = 2/3, so now we just use the x and y coordinates in the point given to find b.
First, we plug in x = -3, y = 2, and m = 2/3. Then, we combine 2/3 and -3 to become -2. Then we add 2 to both sides, and we get b = 4.
The final slope equation is then:
Which is answer D.
Answer:
(1,-2)
Step-by-step explanation:
x+8y=-15
7x+8y=-9
put x in right and make it a -
8y=-15-x
7x+8y=-9
use 8y to substitute into an equation
7x-15-x=-9
subtract 7x to x
6x-15=-9
add 15 to -9
6x=6
divide both sides by 6
x=1
substitute 1 to an equation
7x+1+8y=-9
solve
y=-2

The number of times one needs to use the completely filled cone to completely fill the cylinder with water 24 times
<h3>How to find the volume of a cylinder and cone?</h3>
volume of a cylinder = πr²h
volume of a cylinder = 3.14 × 10² × 20
volume of a cylinder = 6280 cm³
volume of the cone = 1 / 3 πr²h
volume of the cone = 1 / 3 × 3.14 × 5² × 10
volume of the cone = 261.666666667
volume of the cone = 261.7 cm³
Therefore, the number of times one needs to use the completely filled cone to completely fill the cylinder with water is as follows:
number of time = 6280 / 261.7 = 23.9969430646
number of time = 24 times
