y - 2 = -3 (x+1)
point slope form
y-y1 = m(x-x1)
looking at the above equation
the slope is -3
Answer:
y = 36x
Step-by-step explanation:
Given that y varies directly as x, then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 18 when x =
, thus
k =
=
= 36
y = 36x ← equation of variation
Tan x =opposite/ adjacent =9/5
x= arctan(9/5)≈61
Answer:
925 marks.
Step-by-step explanation:
AS Biraj had 20 less marks then the 40% pass mark must be 350+20 = 370.
370 is equivalent to 40%
So 100% = 100*370 / 40
= 925 marks.
