Step 1: Line up the equations so that the variables are lined up vertically.

Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same.

Step 3: Subtract the two equations.

Step 4: Solve the one variable system.

Step 5: Put that value back into either equation to find the other equation.

Step 6: Reread the question and plug your answers back in to check.

You have to begin by declaring what g(f(x)) means. It means that wherever you see an x in g(x) you put in f(x).

It will look like this to start with
g(f(x)) = (f(x) + 5) / (f(x)

Now substitute into this for g(-3)

g(x^2 + 5) = (x^2 + 5 + 5)/(x^2 + 5) It's time to use some numbers.
g(- 3) = ((-3)^2 + 10)/( (-3)^2 +5)
g(-3) = ( 9 + 10 ) / ( 9 + 5)
g(-3) = (19)/14 <<<<<< answer.
C <<<< answer.

Given that R = 4 x + 8 y Find y when x = 4 and R = 32

victus00 [196]

R = 4 x + 8y [ Given ]

when ,

x = 4 and R = 32

★ Substituting the values

=> 32 = 4 × 4 + 8y

=> 32 = 16 + 8y

=> 8y = 32 - 16

=> 8y = 16

=> y = 8/16

=> y = 2

13+x+195=13(x+15)...

LUCKY_DIMON [66]

First, let's expand the right side. Now our equation is

$13+x+195=13x+195$

Now, we gather all the terms with x in it on the left side, and the numbers without x on the right. We get:

$-12x=-13$

And then we can make this

$12x=13$

We divide both sides by 12 to get x on its own, so x = 13/12 or 1.08
