Subtract 2 from both sides

Multiply both sides by 2

Take the square rot of both sides

Subtract 5 from both sides

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.

The price of an item yesterday was $130. Today, the price fell to $39. Find the percentage decrease.

valentinak56 [21]

Well, the decrease was 130 - 39, that is 91

so... if 130 is the 100%, what is 91 of that in percentage?
well $\bf \begin{array}{ccllll}
amount&\%\\
\textendash\textendash\textendash\textendash\textendash\textendash&\textendash\textendash\textendash\textendash\textendash\textendash\\
130&100\\
91&x
\end{array}\implies \cfrac{130}{91}=\cfrac{100}{x}$

solve for "x"
