for sure it's a negative since the slop is going down.. other than that, that's all I can help you with since I'm barely learning about that too :)
Answer:
c
Step-by-step explanation:
Jessica planted a rosebush in her garden. The rosebush has a height of 30 cm. Each month the rosebush increases by 6 cm. Which equation can be used to determine the height of the plant in centimetres, y, after x months?
the rate of increase of the bush every month is 6 cm
Rate of increase of the bush in x months = 6x
because the bush increases every month, 6x would be added to 30cm
y = 6x + 30
If the bush decreased at a rate of 6cm every month, the equation would be y = 30 - 6x
2810321
2000000
800000
10000
300
20
+ 1
Which would be 2810321 in expanded form.
I hope this helps! :)

Answer:
84.82 inches squared
Step-by-step explanation:
Volume of a sphere formula
Volume=4/3(pi)r^2
r=4.5
therefore
4/3*pi*(4.5)^2=84.8230016469244 inches squared
round to whatever many decimal places
84.82 inches squared
Answer:
(a) 412 +A -B
(b) 412 +A -B + (A-20) -(B+14)
(c) 378 +2A -2B
Step-by-step explanation:
Water flowing in adds to the amount in the reservoir. Water flowing out subtracts from the amount in the reservoir.
__
(a) 412 + A - B . . . . at the end of January
__
(b) Flowing in was (A -20), flowing out was (B +14). In February, we start with the amount at the end of January.
(412 +A -B) +(A-20) -(B +14)
__
(c) Simplifying the above, we have ...
412 -20 -14 +2A -2B = 378 +2A -2B
