Rodney is given twi equations:x-y=11 and 2x+y=19

lozanna [386]

Answer:

x= 10 and y= -1

Step-by-step explanation:

Rewrite your second equation Y= -2x+ 19 then plug it into the first equation.

x- (-2x + 19) = 11

x + 2x - 19 =11

3x - 19 = 11

3x = 30

x = 10

The plug that answer into the first equation and solve.

10 - y = 11

-y = 1

y = -1

What is the explicit equation for this series 25,21,17,13

Neko [114]

Answer:

The explicit rule is:

Step-by-step explanation:

The explicit rule is given by:

$a_n=a_1+d(n-1)$

The given sequence is 25,21,17,13

$a_1=25$

d=21-25

d=-4

We plug in the values into the formula to get;

$a_n=25+-4(n-1)$

$a_n=25-4n+4$

$a_n=29-4n$
