In the diagram triangles ABE and ACD are similar.
jolli1 [7]

Answer:

p = 7.2

q = 6.4

Step-by-step explanation:

if the triangles are similar then the side lengths must be proportional :

AC/BA = CD/BE

9/5 = p/4 cross multiply expressions

5p = 36 divide both sides by 5

p = 7.2

same goes for q

9/5 = (q+8)/8 cross multiply expressions

72 = 5(q+8) divide both sides by 5

14.4 = q+8 subtract 8 from both sides

6.4 = q

What are the points for -3x+6y+5=-7
Novay_Z [31]
-3x + 6y + 5 = -7
<u>                -5    -5</u>
      -3x + 6y = -12
-3x + 3x + 6y = -12 + 3x
<u>6y</u> = <u>-12 + 3x</u>
 6           6
  y = -2 + 1/2x
-3x + 6(-2 + 1/2x) = -12
-3x - 12 + 3x = -12
-3x + 3x - 12 = -12
0x - 12 = -12
<u>     +12   +12</u>
       <u>0x</u> = <u>0</u>
        0     0
         x = 0
-3(0) + 6y = -12
0 + 6y = -12
<u>+0           +0</u>
      <u>6y</u> = <u>-12</u>
       6       6
        y = -2
  (x, y) = (0, -2)
