Quotient means division.

(9x)/16 = 81

9x = 1296

x = 144

The unknown number is 144.

9 * x * 16 = 81
divide both sides by 9
x * 16 = 9
divide both sides by 16
x = 0.5625
double check the answer
9 * 0.5625 * 16 = 81?
yes

Let / f(x)= -5x + 3 and g(x) = 6x - 2. Find f*g and its domain.

lina2011 [118]

Answer:

The correct answer is: Option 3.

Step-by-step explanation:

To begin the problem asks to find $f$ · $g$ which can be defined as $[f*g](x)$ . Now we are given that:

$f(x)=-5x+3\\g(x)=6x-2$

So now we need to 'multiply' our two algebraic expressions as follow:

$fg(x)=(-5x+3)(6x-2)\\fg(x)=(-5x)(6x) +(-2)(-5x)+(3)(6x)+(3)(-2)\\fg(x)=-30x^2+10x+18x-6\\fg(x)=-30x^2+28x-6$ Eqn.(1)

The domain of Eqn. (1) is all real numbers of $x$ .

Which according to the given options , Option 3 is correct.
