Y = mx + b....(5,6)
slope(m) = 5
now we sub
6 = 5(5) + b
6 = 25 + b
6 - 25 = b
- 19 = b
so ur equation is : y = 5x - 19...now we sub in 21 for x
y = 5(21) - 19
y = 105 - 19
y = 86
so when x = 21, y = 86
Answer:
The answer is OB 5 gallons
Step-by-step explanation:
Its because if u divide 20 ÷ 4 you get five and there are 4 quarts in a gallon
the derivitive is just the slope
minimum happens when the derivitive goes from negative to positive, imagine a slope of the function, the minimum is where the slope goes from neative to positive, and to get there, it has to pass through 0
max happens when the derivitive goes from positive to negative
increaseing is when the derivitive is positive
so, based on what you said, the slope of f(x) is 0 at x=-3, x=1 and x=2 since those are where the derivitive is 0 (derivitive is just the slope)
A and B are wrong because the derivitive isn't 0 at those points
C is correct because increasing means that the derivitive is positive, and so therefo since the only hoirontal place in between 1 and 2 is 1.5, it must remain positive throughout and not dip down, C is right
D is wrong then
answer is C
X < = -3
y > = 0
x < = 4.....but all the shading is not here....
I wanna say A is correct....but if A is correct, there would be more shading in ur graph...but it is the closest
