x=-5/2

First, to solve this I’m going to multiply (x+3)(x+4) and (x+1)(x+2).

You get x^2 + 7x + 12 = x^2 + 3x + 2

I want to get x on only one side so I subtract
x^2+3x+2

4x+10=0

I subtract 10 from both sides
4x=-10

Then divide each side by 4
x=-5/2

Two investments totallng $47,500 produce an annual income of $3000. One investment ylelds 9% per year, while the other yields 6%

enot [183]

Answer:

The correct answer is "$5000".

Step-by-step explanation:

The given values are:

Two investments totaling,

= $47,500

Annual income,

= $3000

One investment yields per year,

= 9%

Other yield,

= 6%

Let,

The amount invested in 9% will be "x".
The amount invested in 6% will be " $47,500-x$ ".

Now,

⇒ $0.09x+0.06(47,500-x)=3000$

⇒ $0.09x+2850-0.06x=3000$

⇒ $0.03x+2850=3000$

⇒ $0.03x=150$

⇒ $x=\frac{150}{0.03}$

⇒ $x=5000$
