Answer:
Both the relations are functions, the correct answer is a.
Step-by-step explanation:
In order to solve this problem we will first find the inverse relation as shown below:
Functions are relations between two groups of numbers, for which the input must generate only one output. Using this definition we can classify both the relation and its inverse as a function, therefore the correct answer is a.
The account A has amount $600 and B has $1600.
<u>Step-by-step explanation:</u>
The given equations are:
a+b=2200 ⇒1
0.03a+0.05b=98 or +
⇒2
Change the first equation by isolating a,
a = 2200-b. ⇒3
Apply equation 3 in 2,
+
=98.
66- +
=98.
66+ = 98.
6600+2b=9800.
2b=9800-6600.
2b=3200.
b=1600.
Substitute b value in equation 3
a=2200-1600.
a=600.
