Answer:
5 x + 3 = 23
Step-by-step explanation:
Answer:
So the value is 18 dollars off which is $42
Step-by-step explanation:
Well we know 50% of 60 is 30 so we want to multiply 60 x 30 = 180 and the denominator would be 100 so 180/100 now we make 180, 18! which makes 18 dollars off so 60 - 18 = 42
using the FOIL method the equation gets pretty long
Multiply each term by each term and combine like terms the given equation simplifies to:
f(x) = -2x^5 - 9x^4 - 8x^3 + 15x^2 +28x + 12
The degree is equal to the highest exponent, which is the 5 on -2x^5
The degree is 5
The y intercept is the value of y when x is 0
Replace all the x's with 0 and solve the equation:
f(x) = -2(0)^5- 9(0)^4 - 8(0)^3 + 15(0)^2 +28(0) + 12
= 0 -0 -0 + 0 +0 +12 = 12
The y intercept is (0,12)
The answer is $108.60 because $25.67 x 3= 77.01+ $23.55= 100.56 x 8% = $8.0448 + $100.56= $108.60
