Yes it is. Ax+By=C is standard form. :)
Answer:
The charges paid for the first four days are:
Step-by-step explanation:
To obtain the charges paid for the first 4 days, you must use the given explicit rule given:
Where:
- <em>n = Number of days the person rents the car.</em>
As we need to obtain the charges to 4 days, we replace this value in the explicit rule:
- f (n) = 28n + 32
- f (4) = 28(4) + 32
- f (4) = 112 + 32
- <u>f (4) = 144</u>
With these calculations, <u>you can identify the charges paid for the first 4 days are $144</u>, <em>where $112 is the money by each day of the four days and $32 is the base fee</em>.
For this case we have the following system of equations:

From the first equation we clear "x":

We substitute in the second equation:

We apply distributive property:

We add similar terms:

We add 65 to both sides:

We divide between 22 on both sides:

We look for the value of the variable "x":

Thus, the solution of the system is:

Answer:
(b) Symmetric property of congruence
Step-by-step explanation:
a) The transitive property says if a=b and b=c then a=c
b) The symmetric property says if a=b then b=a
c) The substitution property says if a=b and a=c then b=c
d) The reflexive property says a=a

The property of congruence of interest here is the <em>symmetric property</em>.
