Question

Slope of 4x – 6y + 9 = 0

Answer 1

Step-by-step explanation:

d = 360 km

t = 5 h

speed = d/t = 360/ 5 = 72 km/h

For converting speed from km/h to m/s multiply the number by 5/18

Thus,

72 x (5/18) = 20 m/s

Thus, the speed of car is 20 m/s

Answer 2

Answer:

x=3/2y+−9/4

Step-by-step explanation:

Let's solve for x.

4x−6y+9=0

Step 1: Add 6y to both sides.

4x−6y+9+6y=0+6y4x+9=6y

Step 2: Add -9 to both sides.

4x+9+−9=6y+−94x=6y−9

Step 3: Divide both sides by 4.

4x/4=6y−9/4

x=3/2y+−9/4

Answer:

x=3/2y+−9/4
