Question

sendo F (x) = 2x + 6
H(x) = 7x+19
calcule f(x)=h(x)
f(3)
h(x)=32​

Answer 1

Resposta:

• x = -13/5 •• f(3) = 12 ••• h(x) = 32 = 13/7

Explicação passo-a-passo:

• f(x) = h(x)

2x+6 = 7x+19

7x - 2x = 6 - 19

5x = -13

x = -13/5

•• f(3) = 2•3 + 6 = 12

••• h(x) = 32

7x+19 = 32

7x = 13

x = 13/7
