1) the vertex of a parable is given for two points, ( -b/2a, -b2-4ac/4a)
2) Now substitute the values in the equation
x = - (-8)/2(-2) = 8/ -4 = -2
y = -(8^2-4(-2)(1)/ 4(-2) = -(64-8) /-8 = 56/8 = 7
v(-2,7)
Answer:
246
Step-by-step explanation:
They could have travelled any distance. In total, they travelled 1.75 times the distance of the first day, but since we do not know the distance of the first day, we have no idea the actual distance. For all we know they could have gone to the moon in the first day.
Answer:
First choice
Step-by-step explanation:
He must ride 60 - 12 miles during the 6 days
Every day he rides x miles, 6 days, 6x miles
so 60 - 12 = 6x
First choice
Answer:
Step-by-step explanation:
yes, because you can rewrite the equation as y = 1/2 - 2x/3
Also, the equation is plotted as a linear line.
