Given the equation y= -3x + 2.5 . When x is 0, what value of y makes the equation true?

2.5

Step-by-step explanation:

plug in 0 where x is in the equation to find y

y = -3x + 2.5

y = -3(0) + 2.5

y = 2.5

check it by subbing 2.5 into the y values

2.5 = -3x + 2.5

-2.5. -2.5

0 = -3x

+3x

3x = 0

x = 0

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
