Please help I put 50 points

y = x+7

Step-by-step explanation:

Assuming all of these numbers are ordered pairs (coordinates)  when x is 1 y is 8, when x is 2 y is 9 and so on.  If you notice y is going up by 1 every time so it follows that the starting point (y intercept) must be 7.  Therefore, our equation will be y = x + 7.  

Test it out:

Let x =2

y = 2 + 7 = 9  This matches our coordinate (2,9) so it's correct.

Let x =4

y = 4 + 7 = 11  This matches our coordinate (4,11) so it's correct.

Feel free to try out the rest of the coordinates, but usually 2 is enough to confirm that your equation is correct.

output = input - equation

y = x - 7

so 7 is your correct equation!!

Step-by-step explanation:

as u can see

When input x is subtracted from output y, we are getting answer 7

like here

imma gonna tell u how 7 is came

1-8=7

2-9=7

3-10=7

4-11=7

so 7 is our equation

its just a explanation okay

so we get our solution

•°• Y = X - 7

hope it may help you!!

The correct answer is option A.

Step-by-step explanation:

For the given triangles to be similar the segment AD must be an altitude of ΔABC.

We can provide a theorem for the same:

If we draw an altitude from the right angle of any right triangle, then the two triangles formed are similar to the original triangle.

Also all the three triangles are similar to each other.

Like here, in the triangle ABC, we draw an altitude from A to the side BC, thus forming 2 triangles; ΔDBA and ΔDAC. These both will be similar to ΔABC.

So, by the theorem it is proven that  ΔABC is similar to ΔDBA.

Therefore, option A is correct.
