Question

São Dadas as Funções f(x)=3x+1 e g(x)= 4/5.x+a , sabendo que f(1) - g(1)= 2/3, calcule o valor de a ?

Answer 1

Resposta:

Explicação passo-a-passo:

Aplicação

f(1)=3*1+1=

f(1)=3+1

f(1)=4

--------

$g(1)=\frac{4*1}{5}+a\\g(1)=\frac{4}{5}+a[tex]</p><p>[tex]f(1)-g(1)=\frac{2}{3}\\4-(\frac{4}{5}+a)=\frac{2}{3}\\4-\frac{4}{5}-a=\frac{2}{3}\\\frac{16}{5}-a=\frac{2}{3}\\\frac{16}{5}-\frac{2}{3}=a\\\frac{48-10}{15}=a\\\\\frac{38}{15}=a$

Answer 2

Resposta:

3x+1=3.1+1

3+1=4

f(1)=4

g(1)=4/5.1+a

4- 4/5+a=2/3

a=2/3-4+4/5

a=-4+22/15

a=-60/15+22/15

a=-38/15
