Answer:
3.6
Step-by-step explanation:
Y=(1/3)x + (-4)
Rise over run
By the way the 1/3 is a fraction
Answer:
6
Step-by-step explanation:
2904 = 2 x 2 x 2 x 3 x 11 x 11 = (2 x 3) x (2 x 2) x (11 x 11)
=> Smallest number by which 2904 must be divided so that it becomes a perfect number MUST belong to
{(2 x 3), (2 x 3) x (2 x 2), (2 x 3) x (2 x 2) x (11 x 11)} = {6, 24, 2904}
It is easy to see that the solution is 6
(this is the smallest number in collection above)
2x² + 3x -8 = 0
a = 2 , b = 3 , c = -8
So..
D = b²-4ac = 9 + 64 = 73
for bigger solution , use x = -b + √D / 2a
For smaller solution, use x = -b - √D / 2a
So
= -3 + √73 / 2. 2
= 1/4 (√73 -3)
Hopefully helpfull.. ^_^
6 pencils = 2 rulers
1ruler= 2 eraser
12 pencil = 4 rulers
4rulers=8 eraser
so 8 erasers are equal to 12 pencils
