Let no of miles be y

  • A=0.7y+70
  • B=0.8y+20

\\ \sf\longmapsto A=B

\\ \sf\longmapsto 0.7y+70=0.8y+20

\\ \sf\longmapsto 0.8y-0.7y=70-20

\\ \sf\longmapsto 0.1y=50

\\ \sf\longmapsto y=\dfrac{50}{0.1}

\\ \sf\longmapsto y=500miles

Answer:

  • 500 miles

Step-by-step explanation:

Let the number of miles is x.

<u>Then for each company we have total charge of:</u>

  • A = 0.7x + 70
  • B = 0.8x + 20

<u>Since A = B, solve for x:</u>

  • 0.7x + 70 = 0.8x + 20
  • 0.8x - 0.7x = 70 - 20
  • 0.1x = 50
  • x = 50/0.1
  • x = 500 miles

HELP I'M SOOOOOO ANGRYYYYY PLEASE HELPPPP<br>determine the values of X for which g(x) is defined​
tiny-mole [99]

Answer: Any real number x as long as x \ne 0 and x \ne -\frac{2}{3}

In other words, anything but 0 or -2/3 is valid.

========================================================

Explanation:

Set the denominator equal to zero and solve for x

2(3x^2 + 2x) = 0

3x^2 + 2x = 0

x(3x + 2) = 0

x = 0 or 3x+2 = 0 .... zero product property

x = 0 or 3x = -2

x = 0 or x = -2/3

If either x = 0 or x = -2/3, then the denominator 2(3x^2 + 2x)  will be zero. But recall that we cannot have zero in the denominator. Dividing by zero is not allowed. The expression is undefined when we divide by zero.

Therefore, we must exclude x = 0 and x = -2/3 from the domain. Any other real number is valid as an x input.

What is the domain of the functions below: b y= 5x/|x−1| −1
sdas [7]

Answer:

<h2>DOMAIN: The set of all real numbers except 0</h2>

\large\boxed{x\in\mathbb{R}-\{0\}}

Step-by-step explanation:

We have a faction.

We know: the denominator must be different from 0. Therefore

y=\dfrac{5x}{|x-1|}-1\Rightarrow |x-1|\neq0\iff x-1\neq0\iff x\neq1
