Answer: 8/7
Step-by-step explanation:
To solve your X int you substitute 0 for y.
X int-
-5x+9(0)=-18
-5x=-18
X= 18/5 and the coordínate is (18/5,0)
Then to solve for y int you substitute 0 for x.
-5(0)+9y=-18
9y=-18
Y= -2 and the coordinate is (0,-2)
Wouldn't it just be 378-223? resulting with r=155?
Y=5x-2 so you have to solve for x
Make y = 0
Then
Y=5x-2
+2. +2
2=5x
Divide by five
X= 2/5
Then
Y=5x-2
Put x into the equation
Y=5(2/5)-2
Y=2-2
Y=0

3(k-x)= -3x-9
3k - 3x = -3x - 9 ← equation without parentheses
3k - 3x + 3x = - 9
3k = -9
k = -9/3
k = -3 ← simplest form
