b= --6

So you multiply both sides by 6
6*5/6(12-5b)=35*6

Which would turn out to be

5(12-5b)= 210

Then divide both sides by 5
and you would get
5(12-5b)/5= 210/5

And you would get 
12-5b=4

Then subtract 12 from both sides
12-5b-12= 42-12 which is
-5b=30

now divide both sides by 5 and you would get

-6

The bottom two questions that correspond to the word problem... I don't get it
lisov135 [29]
So basically, the first question after the word problem is asking you to write an equation to represent the value of Mama's car after a certain amount of years (t). Since the value of her car decreases by 3% each year, you could multiply 3% by the original value of her car, to find what 3% is, OR you could subtract 19,400 (the value of her car after 1 year) from 20,000 INSTEAD of multiplying 20,000 by 3%. 

Equation:  value=20,000 - 600t

To answer the next question, just plug it into the equation you created. 

500<20,000 - 600t

-19500< -600t

32.5>t
Final Answer: It would take at least 32 and 1/2 years for the value of Mama's car to be less than $500. 

Hope this helps!! :)

Elden [556K]

Answer:

Options A) and E)

Step-by-step explanation:

If you use Ruffini's method for polynomials, you can find the roots.

The given picture shows us the first root of the polynomial 5x^{2}-16x+12=0 wich is 2.

Thus, the original polynomial can be written as

(x-2)*(5x-6)=0

Here, you can notice that (x-2) is a factor
