Answer:
6, - 36 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - 
f(x) = x² + 12x ← is in standard form
with a = 1, b = 12, c = 0 , then
x = -
= - 6
Substitute x = 6 into f(x) for corresponding value of y
f(6) = 6² + 12(- 6) = 36 - 72 = - 36
vertex = (6, - 36 )
Answer:
105
Step-by-step explanation:
The line equation in slope-intercept form is given by

where b is the y-intercept and m is the slope.
Then, we need to convert the given equation into the slope-intercept form. Then, by subtracting 10x to both sides, we have

and by dividing both sides by 2, we get

By comparing this result with the first equation, we can see that the slope is m= -5. So, the answer is: -5
Answer:
.1km
Step-by-step explanation:
The tractor can move .01 km in a second so 10 times .01 is .1
so the tractor can move .1km every 10 seconds
The factors are 3 and (4r+y)
Hope this helps :)
