9) -9x - 13 - y = 0<br> 7=-y-3x

Debora [2.8K]

Answer:

The value of x and y is ,

x = $\frac{-5}{3}$ and y = 2

Step-by-step explanation:

The given two linear equation can be written as ,

y + 9x = -13 ....1 and

y - 3x = 7 .....2

Put the value of y from eq 1 into eq 2

i.e (-13 -9x) - 3x = 7

or, -12x = 7 +13

Or, -12x = 20

i.e X = $\frac{-5}{3}$

Now put t his value of x in any above two linear equation

Let put this value on eq 2 to get value of y

so its can be writen as.

y = 3x + 7

or, y = 3( $\frac{-5}{3}$ ) + 7

or, y = -5 +7

i.e Y = 2

Hence the value of x and y is , x = $\frac{-5}{3}$ and y = 2 Answer

Given the functions f(n) = 500 and g(n) = (nine tenths)n − 1, combine them to create a geometric sequence, an, and solve for the

masya89 [10]

Answer:

$A(n) = 500 * (\frac{9}{10})^{n-1$

$A(11) = 174.34$

Step-by-step explanation:

Given

$f(n) = 500$

$g(n) = (\frac{9}{10})^{n-1$

Represent the combination of f(n) and g(n) with A(n)

So, we have:

$A(n) = f(n) * g(n)$

This gives:

$A(n) = 500 * (\frac{9}{10})^{n-1$

To calculate the 11th term, we make use of n = 11

$A(11) = 500 * (\frac{9}{10})^{11-1$

$A(11) = 500 * (\frac{9}{10})^{10$

This gives:

$A(11) = 500 * (0.9)^{10}$

$A(11) = 500 * 0.3486784401$

$A(11) = 174.33922005$

Approximate to 2 dp

$A(11) = 174.34$
