When looking at a rational function f of x equals the quantity x plus three times the quantity x minus two times the quantity x

plus five all divided by the quantity x minus three times the quantity x plus two times the quantity x minus 5, Charles and Bobby have two different thoughts. Charles says that the function is defined at x = –2, x = 3, and x = 5. Bobby says that the function is undefined at those x values. Who is correct? Justify your reasoning.

f(x)=\frac{(x+3)(x-2)(x+5)}{(x-3)(x+2)(x-5)}

Bobby is right, because at x = -2, 3, and 5, the denominator of the function equals zero, which is by definition undefined.

At Luther's party she made three balloon poodles and two balloon giraffes Which used a total of 17 balloons for Jessica‘s party
olga55 [171]

Answer:

The redaction does not explain the situation.  If we assume that 15 balloons were used to make one ballon poodle and three giraffes, then the answer would be 7,5 balloons for 1 poodle, and 2,5 balloons for a giraffe

Step-by-step explanation:

With 15 balloons we make 1 poodle and 3 giraffes.  This means that 7,5 balloons were used to make 1 poodle, and other 7,5 balloons were used to make 3 giraffes.

If we divide   7,5 balloons between 3, we obtain 2,5.  This means that with 2,5 balloons we make 1 giraffe

Plz help me with this i do not understand math stuff
Zarrin [17]

Answer: Pink choice: y= -6x -2

Step-by-step explanation:

In order to be parallel, the slope must be the same. You find the slope as the number or fraction connected to x. <em>("co-efficient" of x in math talk)</em>

In the given equation, that is -6.  (So that knocks out the first two choices)

The other thing to look at is the y-value of the given coordinate,(-1,4)

<em>(The y-value is the second number in the coordinate (x.y) is the pattern)</em>

and compare it to the the last number in the equations in the choices and     Here the Yellow choice has y= -6x + 4 so this line can't pass through the coordinate given, because  +4 in this equation is where the line crosses the y-axis. ("y-intercept"  in math talk)  So yellow choice is out!

The attachment shows what the graphs of the choices look like.

The black line is the correct answer. The given coordinate (-1,4) is the labeled red spot. The blue line is the given equation. (You can see where it "intercepts the y-axis on the +3)   And the green line also has the -6 slope, but misses the point and intercepts the y-axis at 4.)    

I hope the diagram and explanation helps you understand better. It can be confusing.

Find the HCF and LCM of 126 and 234?
Leni [432]

Answer:

Below in bold.

Step-by-step explanation:

Find the prime factors:-

126 = 2 * 3 * 3 * 7

234 = 2 * 3 * 3 * 13

So the GCF =  2 * 3 * 3 = 18.

The LCM = 2 * 3 * 3  * 7 * 13

= 1638.
