This expression represents the average cost per game, in dollars, at a bowling alley, where n represents the number of games: . What is the average cost per game if James bowls 4 games?

$4.75

Step-by-step explanation:

The expression given for then average cost is :

(3n + 7 / n)

If the number of games, n = 4

The average cost becomes :

(3n + 7) / n

Put n = 4 in the equation

(3(4) + 7) / 4

(12 + 7) / 4

19 / 4

= 4 3/4

= $4.75

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
