the first term of an arithmetic sequence is equal to 200 and the common differencence is equal to -10. find the value of the 20t

olga_2 [115]

Answer:

The value for 20th term is 10.

Step-by-step explanation:

First, you have to find the formula for the sequence.

$an = a + d(n - 1)$

$let \: a = 200,d = - 10$

$an = 200 - 10(n - 1)$

$an = 200 - 10n + 10$

$an = - 10n + 210$

Given that the formula of this sequence is an = -10n + 210. Next, you have to find 20th term :

$let \:n = 20$

$20th \: term = - 10(20) + 210$

$20th \: term = - 200 + 210$

$20th \: term = 10$

Solve the system of equations using the substitution method.

ANTONII [103]

The solution of system of equations is: x = 1.6 and y = 1.2

Step-by-step explanation:

Given equations are:

$y = 2-\frac{1}{2}x\ \ \ \ Eqn\ 1\\x-3y = -2\ \ \ eqn\ 2$

Putting $y = 2-\frac{1}{2}x$ in equation 2

$x - 3(2-\frac{1}{2}x) = -2\\x - 6 + \frac{3}{2}x = -2\\x +\frac{3}{2}x = -2+6\\\frac{2x+3x}{2} = 4\\\frac{5x}{2} = 4\\5x = 4 * 2\\5x = 8\\x = \frac{8}{5}\\x = 1.6$

Putting x = 1.6 in equation 2

$1.6-3y = -2\\-3y = -2-1.6\\-3y =- 3.6$

Dividing both sides by -3

$\frac{-3y}{-3} = \frac{-3.6}{-3}\\y = 1.2$

Hence,

The solution of system of equations is: x = 1.6 and y = 1.2
