Answer: Y=-1
Explanation: 2y-3=y-4 (add three on both sides)
2y=y-1 (subtract y on both sides)
y=-1
Given that the insurance pays 80% of the cost of surgery and the surgery cost $9600, the amount of money Vivian will pay will be given as follows:
20/100×9600
=$1960
since she will cater for the deductibles that amount to $500 before the insurance takes over, then the total amount she will have to pay will be:
1960+500
=$2420
Answer:
Function: 
Not Function: 
and 
Step-by-step explanation:
Given

Determine if 
is a function of 
Solving x+y=9
Make y the subject of formula
<em>Hence; y is a function of x</em>
Solving
Subtract x² from both sides
Square root of both sides
This implies that
or 
<em>Because </em><em> can be any of those two expressions, it is not a function.</em>
Solving
Reorder
Take square roots
This implies that
or 
<em>Because </em><em> can be any of those two expressions, it is not a function.</em>
