Answer:

19

Step-by-step explanation:

if the triangles are similar then EG/BC = FG/BD

51/(x+4) = 57/(2x-7) cross multiply expressions

102x - 357 = 57x + 228

102x - 57x = 228 + 357

45x = 585 divide both sides by 45

x = 13

BD = 2x -7 and 13×2 - 7 = 19

Write the equation of a line passing through the points ​(2​, -4​) and ​(2​, -9​). Write the equation in​ slope-intercept form.
Norma-Jean [14]
1. find our slope: y2 - y1/ x2- x 1

-9 + 4= -5
2 - 2 = 0

m = 0

2. now we need to use our point-slope form to find our y intercept

point-slope form: y - y1 = m(x - x1)

y + 4 = 0(x - 2)

distribute:
y + 4 = 0x

3. get y by itself

y + 4 - 4 = y
0x - 4 = 0x - 4

4. write in slope-intercept form:

y = 0x - 4
OR
y = -4

Help on number six seven eight nine 10 11 12 13 14 15
shepuryov [24]
Easiest ways to solve them are to take the denominator and numerator and and divide the one you are asked to use to answer and divide and see if it works on both. 
  Example: first     105 / 15 = 7 )  Then: 105 / 7 = 15
                             119              )             119 / 7 = 17

Hope I helped. :D
