If Y is directly proportional to x and y = 10 when x = 2, find I) an equation connecting x and y
ii) the value of y when x = 10
III) the value of x when y = 60

p. s please give me a answer quickly

I) Y=5x

II) Y=50

III)X=12

Step-by-step explanation :

I) Y=5x

II) Y=5(10)

Y=50 when x=10

III)Y=5x

60=5x

X=60/5

X=12 when y=60

Hope this helps..

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
