 f(x) = 4x + 3
g(x) = -2x + 5

(f · g)(5) = (4(5) + 3)(-2(5) + 5)
(f · g)(5) = (20 + 3)(-10 + 5)
(f · g)(5) = (23)(-5)
(f · g)(5) = -115

Answer:

a) - 11x - 94y / 12    b)  x -4 / 5- 3x   c) 12x - 11 /10y

Step-by-step explanation:

a)  2x - 6y / 4    -  4y - x/ 12    -   4x - 20y /3

6x - 18y / 12 -     4y - x / 12              -  16x - 80y / 12

= 5x - 14y / 12     - 16x - 80y / 12

- 11x - 94y / 12

b) x /5 -    4/ 3x =  x -4 / 5- 3x

c) 2x -3/ 5y  -    5- 2x / 10y + x/y

4x - 6 /10y   -  5-2x/ 10y +  10x / 10y

2x - 11 / 10  + 10x / 10y

= 12x - 11 /10y

At the city museum, child admission is $5.20 and adult admission is $8.90 . on friday, 159 tickets were sold for a total sales o
Zinaida [17]
Total tickets sold = 159
Total sales = $1100.60
Child admission = $5.20
Adult admission = $8.90

Assumed all 159 tickets are Child admission tickets
Total sales = 159 x 5.2 = $826.80

Difference in amount = $1100.60 - $826.80 = $273.80
The difference must be contributed by the Adult Admission Tickets, which has a difference of $8.90 - $5.20 = $3.70

$273.80 ÷ $3.70 = 74 adult tickets

159 - 74 = 85 child tickets
