because
Answer:
(a)y=-10x
(b)x=0.9
Step-by-step explanation:
If y varies directly with x, we write:
Therefore, a direct variation equation relating y to x is:
(a)y=-10x
(b)When y=-9
Substituting y=-9 into the equation obtained in (a) above
If x=0.62y (x=dollar, y=sterling), then you can multiply both sides by 350 to get 350x=0.62*350y=217 sterlings
