The correct answer is the first option which is negative 2
no, it is constant for a while then changes at 90gallons
Hey!
In order to simplify this equation, we'll first have to multiply both sides of the equation by v. This will give us v on its own.
<em>Original Equation :</em>

<em>New Equation {Added Multiply Both Sides by V} :</em>

<em>Solution {New Equation Solved} :</em>

Now we'll switch sides to get v on the left side of the equation which is generally where we always want the variables to be located in these types of equations.
<em>Old Equation :</em>

<em>New Equation {Switched} :</em>

Now we'll divide both sides by v to get v on its own.
<em>Old Equation :</em>

<em>New Equation {Added Divide Both Sides by V} :</em>

<em>Solution {New Equation Solved} :</em>

<em>So, this means that in the equation

Step-by-step explanation:
Given
Slope (m) = -5
Point
(x1 , y1) = ( 6 , 3)
So the equation is
y - y1 = m ( x - x1)
y - 3 = -5 ( x - 6)
y - 3 = -5x +30
5x + y = 30 + 3
5x + y = 33
5x + y - 33= 0
Which is the required equation.
Hope it will help you :)
Answer:
C) 75 + 50x = 25 + 70x
Step-by-step explanation:
ABC Tech:
$50 an hour. So,for x hours= 50 * x = 50x
Service charge = 75 + 50x
Tech Squad:
$70 an hour. So,for x hours= 70 * x = 70x
Service charge = 25 + 70x
C) 75 + 50x = 25 + 70x
50x - 70x = 25 - 75
-20x = -50
x = -50/-20
x =5/2 = 2
