If f(x) = [x] - 5, what is (86)?

tatuchka [14]

Answer:

$81$

Step-by-step explanation:

I am assuming that you are asking what is [x] - 5 if f(86).

When you have this kind of question, what you do is to substitute the variable inside the parenthesis, so like what is says, f(x). If the question replaces the variable x with 86, that means you input the number into the equation.

So [x] - 5, if f(86).

Substitute:

86 - 5

Select the correct answer.<br> Rewrite the following equation as a function of x.

ivolga24 [154]

Option B:

$${f(x)}=9280-20x$

Solution:

$$\frac{1}{16} x+\frac{1}{320} y-29=0$

$$\frac{1}{16} x+\frac{1}{320} y-\frac{29}{1} =0$

Take LCM of the denominators and Make the denominators same.

LCM of 16, 320, 1 = 320

$$\frac{1\times20}{16\times20} x+\frac{1}{320} y-\frac{29\times 320}{1\times 320} =0$

$$\frac{20}{320} x+\frac{1}{320} y-\frac{9280}{320} =0$

All the denominators are same, so you can write in one fraction.

$$\frac{20x+y-9280}{320}=0$

Do cross multiplication.

$${20x+y-9280}=0\times 320$

$${20x+y-9280}=0$

Add 9280 on both sides of the equation.

$${20x+y}=9280$

Subtract 20x on both sides of the equation.

$${y}=9280-20x$

Let y = f(x).

$${f(x)}=9280-20x$

Hence Option B is the correct answer.
