Answer:

$ 17172.28

Step-by-step explanation:

Each period is 1/4 year ...in ten years there are 40 periods

Interest in decimal is .036      .....   per period this is  .036/4 = .009

The FV = PV (1+i)^n        FV = Future value  PV = present value  

          FV = 12 000 ( 1 + .009)^40 =17172.28

-3(y-50)=24<br><br> Plz help -sob-
Leni [432]

<u><em>Answer: y=42</em></u>

Step-by-step explanation:

division property of equality is dividing both sides of an equation by the same non-zero number does not change the equation.

divide by -3 both sides of an equation.

-3(y-50)/-3=24/-3

simplify.

y-50=-8

add 50 both sides of an equation.

y-50+50=-8+50

simplify.

-8+50=42

50-8=42

42+8=50

y=42

Hope this helps!

Thanks!

Have a great day!

What are the zeros of the function represented by the quadratic expression 2x^2-5x-3
emmasim [6.3K]
 2x2-5x-3=0 

Two solutions were found :

 x = -1/2 = -0.500

 x = 3

Step by step solution :

Step  1  :

Equation at the end of step  1  :

(2x2 - 5x) - 3 = 0

Step  2  :

Trying to factor by splitting the middle term

 2.1     Factoring  2x2-5x-3 

The first term is,  2x2  its coefficient is  2 .
The middle term is,  -5x  its coefficient is  -5 .
The last term, "the constant", is  -3 

Step-1 : Multiply the coefficient of the first term by the constant   2 • -3 = -6 

Step-2 : Find two factors of  -6  whose sum equals the coefficient of the middle term, which is   -5 .
