Answer:

(x-2)^2+(y+3)^2=4

Step-by-step explanation:

  • A circle's equation consist on the following expression: (x-a)^2+(y-b)^2=r^2, where r is the magnitude of the radio, and (a,b) are the coordenates of the center of the circle.
  • In this case, a=2 and b= - 3, because the circle is centered in (x,y)=(2, - 3).
  • The radio, which is the distance between the center of the radio to any point in its border, equals r=2 (because of the scale of the graphic, in this case two squares of the grid equal 2 units, then r=2).
  • Finally, using the previous information to replace in the equation (x-2)^2+(y+3)^2=4, where the fact that r=2 and 2^2=4 was used.

d = 3/2

a₂₀ = a₁+19d

35/2 = a₁ + 19×3/2

a₁ = 35/2 - 19×3/2 = -11

a₁₅ = a₁+14d = -11 + 14×3/2 = 10

Alysha’s average speed when walking home from the market was 5 mph, and it takes her 21 minutes longer than when she drives to t
Delicious77 [7]

9514 1404 393

Answer:

  3 minutes

Step-by-step explanation:

Let x represent Alysha's time to drive home from the market.

Speed and time are inversely proportional to each other (for the same distance), so we have ...

  (walking speed)(walking time) = (driving speed)(driving time)

  5(x +21) = (8·5)(x)

  x +21 = 8x . . . . . . . . . divide by 5

  21 = 7x . . . . . . . . subtract x

  3 = x . . . . . . .divide by 7

It takes Alysha 3 minutes to drive home from the market.
