Step-by-step explanation:

(f - g)(x)

= f(x) - g(x)

= 3x² + 4x - 6 - (6x³ - 5x² - 2) ← distribute parenthesis by - 1

= 3x² + 4x - 6 - 6x³ + 5x² + 2 ← collect like terms

= - 6x³ + 8x² + 4x - 4

Peggy had three times as many quarters as nickels. She had $1.60 in all. How many nickels and how many quarters did she have? Wh

svlad2 [7]

Let q and n represent the number of quarters and nickels respectively.

q=3n and .05n+.25q=1.6 These are the conditions in mathematical terms.

To solve, use the value of q from the first equation in the second equation to get:

.05n+.25(3n)=1.6 carry out indicated multiplication on left side

.05n+.75n=1.6 combine like terms on left side

.8n=1.6 divide both sides by .8

n=2, since q=3n

q=6

So Peggy had 2 nickels and 6 quarters.

Answer:

Solution given:

f(x) = $\frac{1}{9}$ x-2

let f(x)=y

y = $\frac{1}{9}$ x-2

interchanging role of x and y

x= $\frac{1}{9}$ y-2

x+2= $\frac{1}{9}$ y

y=9(x+2)

y=9x+18

F-¹(x)=9x+18

and

F-¹(-1)=9*-1+18=-9+18=9
