Alonzo, Alice, and Juan all solved the following problem but got different answers:
r-ruslan [8.4K]

Answer:

Juan believes the answer is -2/15.

Step-by-step explanation:

The given problem is :

\dfrac{-1}{3}\times \dfrac{2}{5}

We need to solve the problem.

\dfrac{-1}{3}\times \dfrac{2}{5}=\dfrac{-1\times 2}{3\times 5}\\\\=\dfrac{-2}{15}

So, the answer to the problem is \dfrac{-2}{15}. Hence, Juan is correct.

Y=4x(8-x). Linear or nonlinear? explain.
NemiM [27]

Answer:

not linear

Step-by-step explanation:

this equation becomes y = -4x² + 32x which is a quadratic equation that, when graphed, forms an upside down u-shaped curve (upside down because the x² term is negative; if it's positive then the curve is u-shaped)

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!! :)
