For which rational expression is -5 an excluded value of x?

spayn [35]3 years ago

Ration expressions cause excluded values wherever the denominator equals zero.

So, for any expression like

h(x)=\dfrac{f(x)}{g(x)}

-5 is an excluded value if g(-5)=0

For example, the simplest one would be

h(x) = \dfrac{1}{x+5}

In fact, if you try to evaluate this function at -5, you'd have

h(-5)=\dfrac{1}{5+5}=\dfrac{1}{0}

which is undefined, and thus you can't evaluate the function, and thus -5 is an excluded value.

sdas [7]

Answer:

340 children, 210 adults.

Step-by-step explanation:

Let \ a \ - adults, \ c - children;\\c + a = 450\\0.75c + 2a = 600|\cdot 4\\3c + 8a = 2400;\\\\c + a = 450|\cdot(-3)\\3c + 8a = 2400\\-3c -3a = -1350\\5a = 1050 => a = 210, c = 450 -210 = 340.

Compare the decimals 16.30 and 16.3
pshichka [43]
16.30 and 16.3 equal. If you ever have a problem like that then you just add on a zero.

Example:
19.4500 = 19.45 Just add two zeros on the end
19.45 + two zeros = 1.4500
