CAYB is a quadrilateral

Mathematics
1 answer:
Delvig [45]3 years ago
3 0

Answer:

see explanation

Step-by-step explanation:

CY = CB + BY

     = 6b + 5a - b

     = 5a + 5b

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

CX = CA + AX

     = CA + \frac{1}{3} AB , find AB

AB = AC + CB

     = - 3a + 6b

     = 6b - 3a

Thus

CX = CA  + \frac{1}{3} AB

      = 3a + \frac{1}{3}(6b - 3a)

      = 3a + 2b - a

      = 2a + 2b

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

and

\frac{2}{5} CY

= \frac{2}{5} (5a + 5b)

= 2a + 2b = CX

Hence CX = \frac{2}{5} CY ⇒ Proven

Below is the graph of linear equation F(x)-2x-4
AlexFokin [52]

Answer:

1. B. point B.

2. C. point C.

3. C. point C.

Step-by-step explanation:

1. In order to find the graph's y-intercept, we need to locate the point where the line crosses the y-axis. This will always happen at x=0, therefore, the y-intercept is located at point B (0,-4)

2. In order to find the x-intercept, we need to find the point where the line crosses the x-axis. This will generally happen when y=0, so that will be point C (2,0)

3. In order to find the graph's zero, we need to find the point where y=0. In other words, the graph's zero is the point where the function is equal to zero (the x-intercept) so this will br point C again (2,0)

Given ∆QRS≅∆TUV, QS=5v+3, and TV=6v−9, find the length of QS and TV.?
Kisachek [45]
If <span>∆QRS≅∆TUV, Their corresponding sides would be equal so, 
QS = TV
5v + 3 = 6v - 9
6v - 5v = 3 + 9
v = 12

Now, QS = TV = 5(12) + 3 = 60 + 3 = 63

In short, Your Answer would be Option B

Hope this helps!</span>
