Question

Halla el valor numérico de la expresión 3 ⋅ x − 5 cuando x toma los valores.
a) x = 0
3 ⋅ 0 − 5 = 0 − 5 = −5
b) x = 2
c) x = 1
d) x = −2
e) x = –1
f) x = −3

Answer 1

b) x = 2
3 . 2 – 5= 6–5 = 1
c) x = 1
3 . 1 –5 = 3 – 5 = -2
d) x = -2
3 . -2 – 5 = -6 – 5 = -11
e) x = -1
3 . -1 – 5 = -3 – 5 = -8
f) x = -3
3 . -3 –5 = -9 – 5 = -14

Answer 2

Respuesta:

b) x = 2

3 . 2 – 5= 6–5 = 1

c) x = 1

3 . 1 –5 = 3 – 5 = -2

d) x = -2

3 . -2 – 5 = -6 – 5 = -11

e) x = -1

3 . -1 – 5 = -3 – 5 = -8

f) x = -3

3 . -3 –5 = -9 – 5 = -14
