In the Expression(6 - 9t+8), 9t represents coefficient and variable.

<u>Explanation:</u>

An algebraic expression usually consists of constants, variables and, at least one arithmetic operators like addition, subtraction and coefficients.Variable can be any alphabetic letter from A to Z and it represents a certain unknown mathematical value.Coefficient can be any number being multiplied by a variable.  

In the given expression, 6-9t+8 , 9 is the coefficient being multiplied by variable ‘t ‘ . So 9t represents coefficient and variable.

The cost CC (in dollars) of making nn watches is represented by C=15n+85C=15n+85. How many watches are made when the cost is $38
dangina [55]
\bf \stackrel{cost}{C}=15\stackrel{watches}{n}+85\qquad \boxed{C=385}\qquad \stackrel{cost}{385}=15n+85&#10;\\\\\\&#10;380=15n\implies \cfrac{380}{15}=n\implies \cfrac{76}{3}=n\implies 25\frac{1}{3}=n

so, 25 whole watches and hmmmm just the wristband of another maybe.

To describe a specific arithmetic sequence, Elijah wrote the recursive formula:
11111nata11111 [884]

Answer:

t_{n}  = 30 + 7n, where, n = 0, 1, 2, 3, 4, .........

Step-by-step explanation:

Given the arithmetic sequence in recursive formula.

f(0) = 30 and f(n + 1) = f(n) + 7 ......... (1)

Therefore, putting n = 0 in equation (1) we get f(1) = f(0) + 7 = 30 + 7 = 37 {Since, f(0) is given to be 30}

Again, putting n = 1 in equation (1) we get f(2) = f(1) + 7 = 37 + 7 = 44

And, putting n = 2 in equation (1) we get f(3) = f(2) + 7 = 44 + 7 = 51

and so on.

Therefore, the arithmetic sequence is 30, 37, 44, 51, .......

Therefore, the linear equation of this sequence is given by t_{n}  = 30 + 7n, where, n = 0, 1, 2, 3, 4, .........
