Can anyone help me with this and explain it too?
arlik [135]

Answer:

(6, 3)

Step-by-step explanation:

Midpoint (x_{m},y_{m})=(\frac{x_A + x_B}{2}, \frac{y_A + y_B}{2})\\\\=(\frac{3 + 9}{2}, \frac{6 + 0}{2})\\\\=(\frac{12}{2}, \frac{6}{2})\\\\Midpoint of a line segment (x_M, y_M) = (6, 3)

How to Calculate Midpoint?

The x-coordinate of the midpoint M of the segment \overline{AB} is the arithmetic mean of the x-coordinates of the endpoints of the segment  \overline{AB}. Similarly, the y-coordinate of the midpoint M of the segment  \overline{AB} is the arithmetic mean of the y-coordinates of the endpoints of the segment  \overline{AB}.

Find the length of the missing side.
ryzh [129]

Answer:

  85 ft

Step-by-step explanation:

The Pythagorean theorem tells you the length of the hypotenuse (c) is related to the lengths of the legs (a, b) of a right triangle by ...

  c^2 = a^2 +b^2

  c^2 = (40 ft)^2 +(75 ft)^2 = 7225 ft^2

  c = √(7225 ft^2) = 85 ft

The length of the missing side is 85 ft.

Find the slope and write it in slope intercept form
Afina-wow [57]

Answer:

y= 1/2x -7

Step-by-step explanation:

Find the y-intercept. It is where the line crosses "y" which is -7

Next find the rise and the run for "x"

Rise - 1

Run - 2

Then put them in slope intercept form

y=1/2x -7
