Suppose that fx 3x5 and gx 2x15 a Solve fx gx Suppose that

Suppose that f(x) =3x+5 and g(x) = -2x+15.

a. Solve f(x) = g(x).

Suppose that f(x) =3x+5 and g(x) = -2x+15. a. Solve f(x) = g(x). b. Solve f(x) g(x).

f(x) =3x+5 and g(x) = -2x+15

a) f(x) = g(x)

3x +5 = -2x +15

5x = 15-5

5x = 10 ---> x = 2

b) f(x) > = g(x)

3x +5 >= -2x + 15

5x +5 > = 15

5x > = 15-5

5x >= 10

x > =2
