Answer:
The x-coordinate of the solution is x=3
Step-by-step explanation:
we have
------> equation A
------> equation B
Solve the system of equations by substitution
Substitute equation B in equation A and solve for x




Find the value of y
------>
The solution of the system of equations is the point (3,2)
therefore
The x-coordinate of the solution is x=3
The volume of a cone varies jointly with the area of the base and the height of the cone.

where
V = volume
k = constant of proportionality
A = area of the base
h = height of the cone
The given info is for A = 27, and h = 6, then V = 54 (all using appropriate units for area, length, and volume, respectively.)
Now we can find k, the constant of proportionality.
V = kAh
54 = k * 27 * 6
k = 54/(27 * 6)
k = 1/3
The formula is

Now we use the second set of info, the height and the volume, and we find the area of the base.




Answer: the area of the base is 31 cm^2
Answer: 3z^2 + 3z +2
Hope this helps : )
Answer:
$49,893.6
Step-by-step explanation:
$555.26/mo(30yr)(12 mo/yr) - $150000 = $49,893.6
The Y-intercept is showing how many candy bars were sold in 2000 since x is every year after 2000 (hope that makes sense)
