The coordinates for three points of a rectangle are (2, 6) (2, 9) and (8, 6). What is the coordinate for the fourth point in the
saw5 [17]

Answer:

(8,9)

Step-by-step explanation:

Given

A = (2,6)

B = (2,9)

C = (8,6)

Required

Determine the 4th point

The coordinate point of a horizontal or a vertical rectangle is given as:

(x1,y1), (x2,y2), (x3,y3), (x4,y4)

Where:

x_1 = x_2        x_3 = x_4         y_1 = y_3        y_2 = y_4

So, we have:

A = (2,6) --- (x_1.y_1)

B = (2,9) ---- (x_2.y_2)

C = (8,6) ---- (x_3,y_3)

Using the above equations:

x_3 = x_4=8        

y_2 = y_4 = 9

Hence, the coordinate of the 4th point is:

(x_4,y_4) = (8,9)

Jen Butler has been pricing​ Speed-Pass train fares for a group trip to New York. Three adults and four children must pay $ 99. 
8090 [49]

Answer:

An adult ticket is 17

A childs ticket costs 12 dollars

Step-by-step explanation:

Let a = adult price

c = child price

3a + 4c = 99

2a + 3c = 70

Multiply the first equation by 2

2(3a + 4c) = 99*2

6a + 8c = 198

Multiply the second equation by -3

-3 (2a + 3c) = 70*-3

-6a -9c = -210

Add these new equations together

6a + 8c = 198

-6a -9c = -210

----------------------

     -c = -12

Multiply by -1

        c = 12

A childs ticket costs 12 dollars

Now we need to find the price of an adult ticket

2a + 3c = 70

2a + 3(12) = 70

2a +36 = 70

Subtract 36 from each side

2a +36-36 =70-36

2a = 34

Divide by 2

2a/2 = 34/2

a = 17

An adult ticket is 17

Geometry math question please help
Nikolay [14]

AD is perpendicular to BC so slope Ad = -1/slope of BC

Slope of BC = (2 - (-1)) / (- 6- 3) = 3 / -9 = -1/3

So slope of AD = -1 / (-1/3) = -3/-1 = 3 Answer
