Its the First Graph
Step-by-step explanation:
The slope is -1 and the y-intercept is 3
x and y coordiantes (1,2) and (2,1)
Answer:
haiii i can only solve for the vertex...
Step-by-step explanation:
so to find the vertex you have to make it to
y - h = a(x - k)^2
i think
(you could also just make it y = a(x - k)^2 + h but i like the second one better)
soo
y + 5 = 3(x + 7)^2
the vertex is
(-7, -5)
and ummm i think the axis for the axis of symmetry .ss
x = 2a/b but im not sure
Answer:
pee
Step-by-step explanation:
i think its a carrot
The speed upstream is the difference between the boat speed and the current speed. It is (12 mi)/(4 h) = 3 mph.
The speed downstream is the sum of the boat speed and the current speed. It is (32 mph)/(4 h) = 8 mph.
The speed of the boat is the average of these: (3 + 8)/2 = 5.5 mph.
The speed of the current is that less the difference: 5.5 - 3 = 2.5 mph.
_____
<u>Check</u>
Boat + Current = 5.5 + 2.5 = 8 mph
Boat - Current = 5.5 - 2.5 = 3 mph
