Step-by-step explanation:
(a)
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when x = 3, y = 18 , then
18 = 3k ( divide both sides by 3 )
6 = k
y = 6x ← equation of proportion
(b)
(i)
when x = 12 , then
y = 6 × 12 = 72
(ii)
when y = 42
42 = 6x ( divide both sides by 6 )
7 = x
Answer:
13
Step-by-step explanation:
to find the length between two point you've got to use the formula
√(x2-x1)^2 +(y2-y1)^2
√(-2-3)^2 + (-4-8)^2
√(-5)^2 + (-12)^2
√ 25+144
√169
