Answer: C) 6

Step-by-step explanation:

Given : The cost in dollars, C, of renting a carpet cleaner is given by the linear equation $C = 20 + 25x$ , where x is the number of days.

To find the number of days it can be used for $170, we put C= 175 in the equation, we get

$175 = 20 + 25x\\\\\Rightarrow\ 25x=170-20\\\\\Rightarrow\ 25x=150\\\\\Rightarrow\ x=\dfrac{150}{25}=6$

Hence, the required number of days = 6.

Find the limit. (If an answer does not exist, enter DNE.) lim ( (1/x)-(1/lxl)) x→0^+

jek_recluse [69]

Answer:

Step-by-step explanation:

The + on the zero means the limit as x approaches 0 from the right side

$\lim_{x \to 0^{+} } (\frac{1}{x} - \frac{1}{|x|})\\ \lim_{x \to 0^{+} } (\frac{1}{x} - \frac{1}{x})\\ \lim_{x \to 0^{+} } (0)\\0$

Is 7 - -4 positive or negative? positive negative

djverab [1.8K]

Answer:

Positive.

Step-by-step explanation:

When you see two negative signs directly next to each other (as shown in the given expression), it will become a positive sign:

7 - (-4) = 7 + 4 = 11

Positive is your answer.

* To be fair, even if there is only one negative sign, the answer will still be positive, however, I am assuming you are suggesting only the sign, and not the answer.

What are the zeros of the polynomial equation f(x)=x^2-12x+20?

bagirrra123 [75]

$f(x)=x^2-12x+20\\\\\text{The zeros:}\\\\f(x)=0\to x^2-12x+20=0\\\\x^2-10x-2x+20=0\\\\x(x-10)-2(x-10)=0\\\\(x-10)(x-2)=0\iff x-10=0\ \vee\ x-2=0\\\\\boxed{x=10\ \vee\ x=2}$
