Suzi tiene $20 dólares en una cuenta de ahorros. El tipo de intereses es del 10% anual. Cuanto ganara en un año
Damm [24]

Responder:

$ 22

Explicación paso a paso:

Monto principal = $ 20

Tasa de interés = 10% = 10/100 = 0.1

$ 20 (1 + 0.1)

$ 20 (1,1)

$ 22

Ganará $ 22 después de un año.

The slope of a line that passes through points (5, 14) and (-4, y) is 4/9. What is the value of y?​
Monica [59]

Answer:

slope=m=4/9

(x',y')=(5,14)

(x",y")=(-4,y)

we have

m=(y"-y')/(x"-x')

4/9=(-4-5)/(y-14)

4y-56=-81

4y=-81+56

y=-25/4
