2 + 3y = 33<br>3.x - 2y = 0​
Free_Kalibri [48]

Answer:

1. y = 31/3

2. y = 3/2x

Step-by-step explanation:

1.

2 + 3y = 33

3y = 33 - 2

3y = 31

y = 31/3

2.

3x - 2y = 0

-2y = -3x

2y = 3x

y = 3/2x

Hope this helps

The value of -1 is a lower bound for the zeros of the function show below.
dedylja [7]

To perform this check, you must use the following theorem: a is a lower bound for the zeroes of f(x) if, when divide f(x) by (x-a), the quotient and the remainter alternate signs.

Since the long division yields the result

\dfrac{x^4+x^3-11x^2-9x+18}{x+1}=x^3-11x+2+\dfrac{16}{x+1}

You can see that the signs don't alternate (the last two terms are positive). So, -1 is not a lower bound.

In fact, the actual roots of the polynomial are -3, -2, 1, 3, so as you can see there are roots smaller than -1.
