Answer:

x⁴ - x³ + 2x - 6

Step-by-step explanation:

Apparently i cannot write the equation needed so we will call it r(x) and the 2 given equations, a(x) and b(x) respectively

r(x) is the same as a(x) - b(x)

a(x) - b(x)

= x⁴ - 3x² + 5x - 7 -(x³ - 3x² + 3x -1)

= x⁴- x³ + (- 3x² + 3x²) + (5x - 3x) + (- 7 + 1)

= x⁴ - x³ + 2x - 6

A television costs $350 before sales tax is applied. The final cost of the television was $378.

lana [24]

To get the answer we can use proportion. We know that 350 its 100% and 378 its 100% + taxes.
350% ------------ 100
378% ------------ x
cross multiply now
350*x=378*100
350x=37800 /:350
x=108
Now we see that taxes its 8%, because final price its 100% + taxes = 108%
