12*(8*x-6)-(x+9)=0

Pull out like factors :

   8x - 6  =   2 • (4x - 3) 

Equation at the end of step2:

24 • (4x - 3) - (x + 9) = 0

Solving a Single Variable Equation:

 4.1      Solve  :    95x-81 = 0 

 Add  81  to both sides of the equation : 

                      95x = 81

Divide both sides of the equation by 95:

                     x = 81/95 = 0.853

 x = 81/95 = 0.853

Based on the graph, what is the initial value of the linear relationship?
alex41 [277]

Answer: two over three

Step-by-step explanation:

y=ax+b

line intercepts y at (0,-2)

Therefore, y=ax-2

Substitute x = 3 in y =ax-2

y=3a-2

To find the x-intercept, y = 0

3a-2=0\\3a=2\\a=\frac{2}{3}

The slope is 2/3

y-intercept is -2

So two over three

zlopas [31]

Answer:

The total cost will be the same for both companies after 20 miles.

Step-by-step explanation:

First, I wrote the equations:

Laguna's Truck Rentals: 2x + 20

Salvatori's truck rentals: 3x

To find when the total cost for both companies will be the same, I kept substituting numbers for the variable until it worked. So, the total cost for both companies will be the same after 20 miles. Hope this helped!
