Since you know that DA and DC are equal in length, you can say 2x-3=x+2, when you add 3 to both sides, it becomes 2x=x+5, subtract x from both sides, and you find that x=5
THE ANSWER IS: y = -x+9
y=mx+b
m=slope=(y2-y1)/(x2-x1)
use the points (0,9) and (9,0)
(0-9)/(9-0) = -9/9 = -1
so m=-1
b is the y-intercept which is where x=0
the line crosses the y axis at y=9
so b=9
plugging in m and b into y=mx+b,
you get y=-x+9
Answer:
x = z - m + y
Step-by-step explanation:
Given:

To solve for x-term, we have to isolate it. We can do by subtracting m-term both sides and add y-term both sides.

Therefore, the answer to this question is x = z - m + y

Step-by-step explanation:
first you go by counting by 2s and when your done it says one will ride alone so minus 1 that is 5 so the answer will be 5
