Using the distance formula , find the distance from the center of your habitat to the point (x, y). Write this equation. Your an
alexdok [17]

Answer:

See explanation

Step-by-step explanation:

The distance formula is given by:

d =  \sqrt{ {(x_2-x_1)}^{2} +  {(y_2-y_1)}^{2}  }

We want to find the distance between (a,b) and (x,y).

The center of the habitat is missing in the question.

Assuming the center is (a,b) where a and b are real numbers, then we can use the distance formula to obtain:

d = \sqrt{(x - a)^{2} +  {(y - b)}^{2}  }

For instance if the center of your habitat us (2,-1), then

d = \sqrt{(x - 2)^{2} +  {(y  + 1)}^{2}  }

Solve the simultaneous equations 4x+8y=-4 2y-5x=23
ad-work [718]

Answer:

x = -4,  y = 3/2

Step-by-step explanation:

simplify the 1st equation by dividing each term by 4 to get:

x + 2y = -1

-5x + 2y = 23

Subtract to get: 6x = -24

x = -4

find 'y':    2y - 5(-4) = 23

               2y + 20 = 23

               2y = 3

                y = 3/2
