you cannot have a negative amount of rainfall, so the predicted value of -32.4cm doesn't make sense.
Wow dude u in college, i wish i could help but im in middle school 8th grade. I guess u could try to go on google and kad academy or whatever its called to get help if no one knows how to do this
The equation seems to be
1
-------- = 5 ^ (x + 4)
25
In that case, this is the solution, stept by step:
1) factor 25: 25 = 5^2
1
=> ----------- = 5^(x + 4)
5^2
2) invert 5^2
=> 5^(-2) = 5^(x+4)
3) Given that the bases are equal, the exponents also have to be equal:
=> - 2 = x + 4
3) transpose +4:
=> - 2 - 4 = x
=> x = - 6
Answer: - 6
9^2 × 9^6=9^10/9^2
When multiplying exponents, if the bases are the same you add the exponents.
9^2 × 9^6 = 9^(2+6)=9^8
When dividing exponents, I'd the bases are the same you subtract the bottom exponent from the top.
9^10/9^2=9^(10-2)=9^8
9^8=9^8
Solution: 9^10 over 9^2
Answer:
y - 3 = 2(x + 1)
y - 3 = 2x + 2
y = 2x + 5
