Answer:
(2, 3 )
Step-by-step explanation:
Given the 2 equations
x - 2y = - 4 → (1)
2x + y = 7 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the y- term
4x + 2y = 14 → (3)
Add (1) and (3) term by term to eliminate y, that is
5x = 10 ( divide both sides by 5 )
x = 2
Substitute x = 2 into either of the 2 equations and evaluate for y
Substituting into (2)
2(2) + y = 7
4 + y = 7 ( subtract 4 from both sides )
y = 3
Solution is (2, 3 )
Answer:
<h2>3 + 4(n - 1)</h2>
Step-by-step explanation:
let r be the common differenc of the sequence
Term 12 - Term 7 = (12 - 7)r
then
47 - 27 = 5r
then
20 = 5r
then
r = 4
term 7 = term 1 + (7 - 1)r
then
27 = term 1 + 6r = term 1 + 24
then
Term1 = 27 - 24 = 3
<em><u>therefore </u></em>
the standard explicit formula of the sequence is :
term 1 + (n - 1)r = 3 + 4(n - 1)
Answer:
PN= $17,800
Step-by-step explanation:
<u>La formula general para calcular el activo de una empresa es la siguiente:</u>
<u></u>
A= PN + P
El activo es igual al patrimonio neto y el pasivo.
Debemos intercambiar los términos:
PN= A - P
Activo:
Caja= 10,000
Bancos= 13,500
Equipos de computación= 2,400
Documentos por cobrar= 5,100
Pasivo:
Cuentas por pagar= 8,000
Documentos por pagar= 4,000
Intereses por pagar= 1,200
PN= 31,000 - 13,200
PN= $17,800
