Answer:

\large\boxed{M_{XY}\left(-\dfrac{7}{2};\ \dfrac{3}{2}\right)\to M_{XY}(-3.5,\ 1.5)}

Step-by-step explanation:

The formula of a midpoint of AB

A(x_A,\ y_A),\ B(x_B,\ y_B)\\\\M_{AB}\left(\dfrac{x_A+x_B}{2};\ \dfrac{y_A+y_B}{2}\right)

We have the points X(2, -1) and Y(-9, 4).

Substitute:

M_{XY}\left(\dfrac{2+(-9)}{2};\ \dfrac{-1+4}{2}\right)\\\\M_{XY}\left(\dfrac{-7}{2};\ \dfrac{3}{2}\right)

The answer is x = 6
Explanation:
First, you must assume that 5x-10=20. Next, you add 10 to 20, which makes the equation 5x=30. Next, divide 30 by 5, which then makes the equation x=6. When you substitute 6 in the original equation, it works, because 5(6)-10 equals 20.

Find the 10th term of the following geometric sequence: 2, 8, 32, 128.        A. 164,357   B. 621,325   C. 524,288   D. 248,221
Galina-37 [17]
Common ratio = 8/2 = 32/8 = 4

10th term  = a1*r^(n - 1)   where a1 = 2 , r = 4 and n = 10
                = 2 * 4^9
                =  524,288

Where are white blue and red boat in the Marina three fourths of the boats in the Marina are white for seventh of the remaining
xeze [42]

Answer:

28

Step-by-step explanation:

Here is the complete question used in answering this question :

Three-fourths of the boats in the marina are white. 4/7 of the remaining boats are blue , and the rest are red . If there are 9red boats, how many boats are in the marina?

We first have to determine the fraction of the boats that are red

1 - (\frac{3}{4} + \frac{4}{7})

1 - \frac{21 + 16}{28}

1 - \frac{37}{28}

1 - 1\frac{9}{28}

= 9/28

so, 9/28 of the boats are red

let b represent the total number of boats

9/28 x b = 9

to find b, divide both sides of the equation by 28/9

b = 28
