Answer: b = -20
Step-by-step explanation: I have difficulty reading the table of values of (x,y). I picked just the first (10, -120) to calculate b.
y = -10x + b
-120 = -10(10) + b
b = -20
That should work for all the points:
(20, -220) : -220 = -10(20)-20 - Yes, etc.
But the values towards the end of the table don't makes sense/don't work. (0, -2)????
D) 1/m^18
Explanation:
(m^-2/m-1m5)^3
m^-6/m^-3m^15
1/m^6 / m^15/m^3
1/m^6 / m^12
1/m^6 (1/m^12)
1/m^18
let me know if you want clarification
2x^2-3+11+7x^2-3x-4= 9x^2-3x+4
9x^2-3x+4-14x^2=-5x^2-3x+4
ANSWER: -5x^2-3x+4
