Mathematics

Answer:

-39

Step-by-step explanation:

The expression in this problem is

3x^3 - 3y

We want to evaluate this expression when

x=-3

y=4

Substituting into the expression, we find:

(-3)^3 - 3(4) = \\-27 - 12 = \\-39

Because

(-3)^3 = (-3)(-3)(-3) = -27

and

3\cdot 4 = 12

And this expression is a polynomial, which is an expression consisting of more than one algebraic terms (in this case, two of them)

In an arithmetic sequence {an}, if a1 = 5 and d = 3, the first 4 terms in the sequence are
noname [10]
A1 represents the first term

d represents the common difference.....and since the common difference is 3, u have to add 3 to each term to find the next term....because with an arithmetic sequence u add to find the next term, whereas, in a geometric sequence u multiply to find the next term

5...first term
5 + 3 = 8...2nd term
8 + 3 = 11...3rd term
11 + 3 = 14...4th term

zhannawk [14.2K]

Answer:

Step-by-step explanation:

4.2x+4.7=18.6

Multiple each term by 10

42x + 47 = 186

Collecting like terms

42x = 186 - 47

42x = 139

x = 139/42

x = 3 13/42 or 3.3
