Answer:
EASY XD.... your basically look at like $360,000
18,000×20=$360,000
The range of the function is A
Answer:
x = 44 and y = 4
Step-by-step explanation:
Given:
x - y = 40
2x + 3y = 100
Isolate for x in the first equation:
x = 40 + y
Sub x = 40 + y into the second equation and solve for y:
2(40 + y) + 3y = 100
80 + 2y + 3y = 100
5y = 20
y = 4
Sub y = 4 into the equation for x:
x = 40 + 4
x = 44
Therefore, x = 44 and y = 4
Answer:
Yes
Step-by-step explanation:
If the next expands by a factor of 4, all the sides will be 4 times as big. This means that the area expands with 4x4 = 16, and the volume with 4x4x4=64.
