Question

determinar o coeficiente a e b desta função do 1 grau F(x)=5x+4

Answer 1

a)

f(x) = 5x + 4
a = 5 e b = 4

f(x) = a.x + b

R.: a = 5 ; b = 4

**************************
b)
G(X) = - 43X
0 = - 43x 
- 43x = 0
a = - 43; b = 0

*************************
c)
y = 5 + 9x 
0 = 9x + 5
9x + 5 = 0
a = 9; b = 5

*************************
d)
f(x) = 8x - 14
0 = 8x - 14
8x - 14 = 0
a = 8; b = - 14
