Find the midpoint between the points (7, -2) and (-4, 2). Write your answer in the proper form using parentheses
Elan Coil [88]

Answer:

( 1.5, 0)

Step-by-step explanation:

1. Find the coordinates ; in this case (7,-2) and (-4, 2)

2. Plug it into the formula (x1 + x2 ÷ 2 ) , (y1 + y2 ÷ 2)

3. ( 7 +  -4 ÷2) = 1.5    And    ( -2 + 2 ÷ 2) = 0

4. Therefore, the midpoint is ( 1.5, 0 )

Solve for d 6d -11/2 = 2d -13/2. Please answer quickly
Slav-nsk [51]

6d -11/2 = 2d -13/2

Subtract 2d from both sides

6d -11/2 - 2d = 2d -13/2 - 2d

Simplifying

4d -11/2 = -13/2

Add 11/2 to both sides

4d -11/2 + 11/2 = -13/2 + 11/2

Simplifying

4d = -2/2

4d = -1

Divide both sides by 4

4d/4 = -1/4

Simplifying

d = - 1/4

wolverine [178]

Answer:

53 Meters.

Step-by-step explanation:

34*34 + 41*41 = 2837.

1156 + 1681 = 2837.

The square root of 2837 would be your answer.

34*34 + 41*41 = 53.26349 * 53.26349

a*a + b*b = c*c.

a² + b² = c².
