Answer:
y = - 10
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 2 when x = - 4, that is
2 = - 4k ( divide both sides by - 4 )
= k, that is
k = -
y = - x ← equation of variation
When x = 20, then
y = - × 20 = - 10
Answer:
decreasing
Step-by-step explanation:
since its negative it will slope down
15.48 + 5.16 = p because you have to do the reverse. to find "p" you have to add the amount you subtracted.
