Answer:
1. 0.004, 4%, 4 x 10^-1, 1/4, 4/9
2. 6%, 16%, 1/6, 0.6, 6x 10¹
3. 7%, 7.5 x 10^-2, 3/4, 7/10, 7.5
4. 2%, 3/16, 1/5, 2/9, 2 x 10²
Step-by-step explanation:
Expression: Y = -10/3 X
Y = 10/3
If Y varies directly as X, then;
Y∝X
Y = kX
k is the constant of variation
If Y = 10 and X = -3
10 = -3k
k = -10/3
Substitute k = -10/3 into the expression Y = kX
Y = -10/3 X
This gives the required expression
To get the value of Y when X = -1
Recall that Y = kX
Y = -10/3 (-1)
Hence the value of Y is 10/3
line B I hope this help!! good luckkk
