7-4x=2-9x the answer is x=1
Answer:
11
Step-by-step explanation:
the image above explains it
No; a domain value has two range values.
x = -2 then y = 1 and 2
they would form a vertical line, which tells us that it's not a function
Given:
Volume of a cube = 27,000 in^3
(Note: A cube has equal sides)
The volume of a cube = a^3
So,
![\begin{gathered} 27000=a^3 \\ \sqrt[3]{27000}\text{ = a} \\ a\text{ = 30 in.} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%2027000%3Da%5E3%20%5C%5C%20%5Csqrt%5B3%5D%7B27000%7D%5Ctext%7B%20%3D%20a%7D%20%5C%5C%20a%5Ctext%7B%20%3D%2030%20in.%7D%20%5Cend%7Bgathered%7D)
Therefore, the lenght of one side is 30 inches.
B) 2 (5 + 7) = 2 × 5 + 2 × 7
Distributing the two multiples the five and seven and adds there them together.
