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.

Given the formula, Sn=a 1-r^n/1-r, what is the sum of the first nine terms of the geometric series: 324, -108, 36, -12...

vlada-n [284]

Answer:

243.01.

Step-by-step explanation:

The first term (a) = 324.

The common ratio (r) = -108/324 = -1/3.

So sum of 9 terms is:

S(9) = 324 * (1 - (-1/3)^9) / ( 1 - (-1/3)

= 324 ( 1 - (-0.00005076)) / 4/3

= 324 * 1.00005076 / 1.33333

= 243.012.
