C₄H₉ refers to a hydrocarbon with four carbon (C) atoms and nine hydrogen (H) atoms, which is typically an alkyl group known as butyl. The molecular weight of 114.17 g/mol indicates the mass of one mole of this compound. This molecular formula can represent several isomeric forms, including butyl alcohol and butyl acetate, depending on the arrangement of the atoms.
-4 + c = -9 -4 + 4 + c = -9 +4 c = -9 + 4 c = -5

To solve the equation (4c = 36), divide both sides by 4 to isolate (c). This gives you (c = 36 / 4), which simplifies to (c = 9). Therefore, the solution is (c = 9).
C = 5/9 (f - 32)c = 5/9 (-36)c = -20
To find the number of 4-number combinations from the numbers 1 to 9, we use the combination formula ( C(n, r) = \frac{n!}{r!(n-r)!} ), where ( n ) is the total number of items to choose from and ( r ) is the number of items to choose. Here, ( n = 9 ) and ( r = 4 ). Thus, the number of combinations is ( C(9, 4) = \frac{9!}{4!(9-4)!} = \frac{9!}{4!5!} = 126 ). Therefore, there are 126 different 4-number combinations possible.
-4 + c = -9 -4 + 4 + c = -9 +4 c = -9 + 4 c = -5
2c + 4 - 3c = -9 + c + 5 -c + 4 = c - 4 -2c = -8 2c = 8 c = 4

The compound's empirical formula is CH3N, and its molecular formula is C4H12N. Therefore, the subscript on C in the chemical formula is 4.
c = 4, c squared = 16, 3c squared = 48, 48 + 9 = 57.

To solve the equation (4c = 36), divide both sides by 4 to isolate (c). This gives you (c = 36 / 4), which simplifies to (c = 9). Therefore, the solution is (c = 9).
C = 5/9 (f - 32)c = 5/9 (-36)c = -20
f(x) = 2 * 2 - x + 9 f(-4) = 2 * 2 -(-4) + 9 f(-4) = 4 + 4 + 9 = 17
