Y varies directly with x" means y = constant * x or y = kx ----- (1)1. when x = -1/2, y = 2Put it in (1):2 = k * (-1/2)multiply by 2:4 = k * (-1)4 = -kk = -4y = -4x
"find the value of y when x= -0.3"y = -4x = (-4) * (-0.3) = 1.2
So for each problem, start with y = kxThey give you one x and one y value.Put it in y = kx and find k.Then put x = -0.3 and find y.
Step-by-step explanation:
total students=99
finished entering marks =9\11
let the entered number be x
now,
"x=9\11×99
x=9×9
x=81
again,
99-81=18
the remaining number of students is 18
The answer is C because AO and BO are equal. And with AO being three times the length of CO, BO should be the length of DO
