Isolate the q. Note the equal sign. What you do to one side, you do to the other.
Subtract 4 from both sides
8q + 4 (-4) = 20 (-4)
8q = 20 - 4
8q = 16
Next, divide 8 from both sides to isolate the q
8q/8 = 16/8
q = 16/8
q = 2
q = 2 is your answer
hope this helps
Use exponent rule: x^-y = 1/x^y
6^-3
= 1/6^3
= 1/216
Best of Luck!
Answer:

Step-by-step explanation:




Chun wants to <span>reduce the weight of garbage produced to 85% of the weight produced this month.
This means that, Chun's garbage weight next month should be equal to 85% of his garbage weight this month.
Translating this into an equation, we will find that:
garbage weight next month = 85% of garbage weight this month
garbage weight next month = 0.85 * garbage weight this month
garbage weight next month = 0.85*690
garbage weight next month = 586.5 pounds
Based on the above calculations, his target weight for the garbage next month is </span>586.5 pounds
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)
