Are these proportional? There are two.

Distance formula:

where d - distance, t - time, s - speed

Let the distance be constant, d = k, then the speed is:

Since the distance is constant, the speed is inversely proportional with time

Let the speed be constant, s = k, then the distance is:

The distance is directly proportional with time

Distance formula:

-d=ts.

where d-distance, time-t, speed-s.

Let the distance be constant, d=k,then the speed is:

-s=k/t.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

1/2*qr*rs
