If y varies directly with x, write an equation for the direct variation. then find the value. if y=3 when x=2, find y when x=1 plz show work

since y varies directly with y then

y = kx ( k is the constant of variation )

to find k use y = 3 when x = 2

k = =

equation is : y = x

When x = 1 then y = × 1 =

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
