Lets x is the number of miles

Car Stars Auto Rental charges $35 a day plus $0.25 per mile = 0.25x + 35
Car Express Auto Rental charges $17 a day plus $0.40 per mile =0.40x + 17 


0.25x + 35    = 0.40x + 17
0.25x -0.40x = 17 - 35
      -0.15x    = -18
               x   = -18  /  -0.15
               x   = 120

answer: <span>D. 120 miles </span>

Answer:

d 120

Step-by-step explanation:

0.25x + 35    = 0.40x + 17

0.25x -0.40x = 17 - 35

     -0.15x    = -18

              x   = -18  /  -0.15

<h2>               x   = 120</h2>

Determine whether 81 − 49n4 is a difference of two squares. If so, factor it. If not, explain why.
Mumz [18]

We have

81-49n^4=9^2-(7n^2)^2

so this is indeed a difference of squares. Factorizing would give

81-49n^4=(9-7n^2)(9+7n^2)

making the answer D.

We can further factor the first term here and write

9-7n^2=3^2-(\sqrt 7\,n)^2=(3-\sqrt7\,n)(3+\sqrt7\,n)

but that's clearly out of the scope of this question.

Descried how to derive the quadratic formula from a quadratic equation in standard form
Aleks [24]

Answer:

The standard form of a quadratic equation is:

ax^2+bx+c=0, a\neq 0

Quadratic Formula Derivation:

ax^2+bx+c=0\\

$x^2+\frac{b}{a}x+\frac{c}{a} =0 $

$x^2+\frac{b}{a}x = -\frac{c}{a}$

Completing the Square:

$x^2+\frac{b}{a}x +\frac{b^2}{4a^2} = \frac{b^2}{4a^2}-\frac{c}{a}$

$  ( x+\frac{b}{2a} )^2 =  \frac{b^2-4ac}{4a^2}  $

Square Root property:

$x+\frac{b}{2a}  = \pm \sqrt{ \frac{b^2-4ac}{4a^2}}   $

$x  = -\frac{b}{2a} \pm  { \frac{\sqrt {b^2-4ac}}{2a}}   $

$x  =  \frac{-b\pm\sqrt{b^2-4ac}} {2a}  }   $

find an equation in slope intercept form of a line that passes through the point 2.2 and has a slope m is equal 0 also sketch th
Goshia [24]
Y = mx+b (slope intercept form). I imagine the point is (2,2) and m = 0. So the answer is y = 2. A sketch would be a horizontal line on the x-y plane going through (2,2).
