Answer:
0.3
Step-by-step explanation:
Line is a perpendicular bisector of the angle
The density of the liquid is 1.55 g/mL.
Given the following data:
Mass of liquid = 22.8 grams
Volume of liquid = 14.7 mL
To find the density (unknown) of the liquid:
Density is mass all over the volume of a substance or an object. Thus, density is mass per unit volume of an object.
Mathematically, the density of a substance is given by the formula;
Substituting the values into the formula, we have;
Density = 1.55 g/mL
Therefore, the density of the liquid is 1.55 g/mL.

A) Because the 80 is by itself that would be the start up fee.
B) We are told x is the number of months. Since the X is being multiplied by 30, we know that would be the total monthly cost. This is being added to the 80, which does not have an exponent, so we know this is a single cost, which would be the start up fee.
C) Copying the same format as the given equation above, change the numbers:
f(x) = 20 + 35x
D) I used the same format as the first equation, which meant replacing the start up cost from the original one ( 80) with the start up of the new one (20). Then I changed the monthly cost from the original one (30) with the monthly cost of the new one (35).
E) Replace x in each equation with 8 and calculate the cost of each:
80 + 30(8) = 80 + 240 = $320
20 + 35(8) = 20 + 280 = $300
