The parabola x = y² - 9 opens: <br> a.)up <br> b.)down<br> c.) right <br> d.)left
Zolol [24]

Answer:

Right side towards positive x axis

Step-by-step explanation:

Let us see the basic rule to find the orientation of parabolas.

1.  If power if x is 2 and y is 1 , the parabola opens up or down.

2. If the power of y is 2 and that of x is 1 , the parabola opens right or left.

3. If the coefficient of x^{2} in case 1 is negative it opens downward

4. If the coefficient of y^{2}  in case 2 is negative , it opens left towards negative x axis.

Hence our equation is

x=y^2-9

here is satisfies the case 2. hence it opens right or left . Also the coefficient of  

y^{2} is positive so it opens up to the right side , that is towards positive x axis.

The sum of three times a number b and 33 is at least 35
Harlamova29_29 [7]
I love these problems, because it's just about reading the question. All you need to do is break it down. What do we know the "sum of" something is? We know that it means addition. What are we adding? "three times a number b and 33". Well, how can we express "three times b"? 3b! Right! Well, we know we're adding that to 33, so you're almost done. Right now you should have 3b+33. And what <em>is</em> 3b+33? at least 33. How can we express "at least"? >=, greater than or equal to, right! Finally, we have our answer. 3b+33>=35.

Help me out please !!!!!!!!!!!
Bad White [126]

Answer: A=2, B=5, C=4

Step-by-step explanation:

\frac{6x^{2}+13x-5}{x^{2}-16} \cdot \frac{x+4}{3x-1}\\\frac{(3x-1)(2x+5)}{(x-4)(x+4)} \cdot \frac{x+4}{3x-1}\\\frac{2x+5}{x-4}

So A=2, B=5, and C=4.
