Answer:
x=−0.35
Step-by-step explanation:
2.5x−10.5=64×0.5x
2.5x−10.5=32x
−10.5=32x−2.5x
−10.5=29.5x
− 29.5/10.5=x
−0.355932=x

Answer:
the bottle which cost four dollar and 5 ounces
Answer:
slope = 0
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 8, - 3) and (x₂, y₂ ) = (- 12, - 3)
m =
=
= 0
For this case we have the following equation:

Where, by definition, we have the following variables:
d (x): the daily expense per truck (in dollars)
x: the daily mileage
Therefore, the domain of the function is given by:

Equivalently:
[0, ∞)
Answer:
The input for the function includes all positive real numbers
option d.
