Step-by-step explanation:
<u>Step 1: Define</u>
(x + 5) + (-4x - 2) + (2x - 1)
<u>Step 2: Simplify</u>
- Combine like terms (x): -x + 5 - 2 - 1
- Combine like terms (Z): -x + 2
I think it’s 222 because he runs 18.5 miles every week and 18.5 x 12 = 222
Answer:
1. y = -125000x + 700000
2. Negative
3. Positive
Step-by-step explanation:
1. The no. Of gallons before irrigation
= 700000
After irrigation = 200000
This means that there was a reduction of 500000 gallons in 4 hours which indicates that 125000 gallons were used (on an average) in 1 hour
So the equation is
y = 700000 - 125000x
Hope this helps

Answer:
-10
Step-by-step explanation:
9^-8 x 9^-2 = a^b
We know that x^y * x^z = x^(y+z)
9^-8 x 9^-2 = 9^(-8+-2) = 9^(-10)
a= 9
b = -10
