So the problem is
4x-5=7+4y
solve for y
easy
minus 7 from both sides
4x-5-7=7-7+4y
4x-12=0+4y
4x-12=4y
divide both sides by 4
x-3=y
y=x-3
His salary before the cut would be $36,432
Answer:
a) We get
So, Is the result of A+B is a polynomial:Yes
b) We get
So, Is the result of A-B is a polynomial:Yes
c) We get
So, Is the result of A.B is a polynomial:Yes
Step-by-step explanation:
We are giving the polynomial equations:
We need to find
a) A+B
So, we get
So, Is the result of A+B is a polynomial:Yes
b) A-B
So, we get
So, Is the result of A-B is a polynomial:Yes
c) A . B
So, we get
So, Is the result of A.B is a polynomial:Yes
Answer:
Total = Principal * (1 + rate)^2
Total = 12,484 * (1.08)^2
Total = 14,561.34
