Which factorization can be used to identify the real zeros of the function f(x)= -20x + 23x -6

Since f(x) is a first order equation, it has only one zero

f(x) = -20*x +23*x -6

This means that

f(x) = (-20 + 23)*x -6

f(x) = (3)*x -6

If we mame the previous equation equal to zero >

(3)*x -6 = 0

x  = 2

which means, the factorization is equal to

(x-2) = 0

f(x) = 3*(x-2)

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
