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.
Answer:
B
Step-by-step explanation:
Let, the two-digit number = xy
It is given that, xy = x + y²
Then, number which obey the rule is 89.
Check: 8 + 9² = 8 + 81 = 89 [ Itself ]
In short, Your Answer would be: 89
Hope this helps!
Answer:
Step-by-step explanation:
Area is + 111.6 square meters
Formula : A/ 3.14 / 2
111.6 / 3.14 = 35.54
35.54 is the radius so multiply by 2 to get diameter .
35.54 / 2 = 17.77
Hope that’s right:)
