Sasha can run at an average speed of 9 3/4 min/mi. she runs at this speed for 68 1/4 min.
how many miles does sasha run?
choice b is correct answer.
given equation is :
-3n(7n-5) = 0
zero-product property states:
if a.b = 0 then
a = 0 or b= 0 (or both)
applying zero-product property to given equation, we get
-3n = 0 or 7n-5 = 0
-3n = 0
multiplying by -1/3 to both sides of above equation ,we get
-1/3(-3n) = -1/3(0)
n = 0 which is answer.
secondly, we solve
7n-5 = 0
adding 5to both sides of above equation, we get
7n-5+5 = 0+5
7n = 5
multiplying by 1/7 to both sides of above equation , we get
1/7(7n) = 1/7(5)
n = 5/7 which is answer.
slope intercept form is y = mx + b
the be is your y intercept (0,8)
the m is your slope (2) by putting a one under it you can graph it more easily:
to get your next point follow the slope which is
what this means is we follow the fraction and go up 2 and right one (positive slope) or down 2 and left one (positive slope) to get our next points
for a negative slope it would be up and then left or down and then right
as you can see, the bigger triangles given sides are 4 times bigger than the little triangle's sides. when you divide 52 (the side being compared to x) you get 13.
