4/9m=slope
it has no y intercept so it passes through the origin
4/9m=same slope
4/9+1= a parallel line to this
You FOIL (First, Outer, Inner, Last)
If you FOIL, you should get 2y^2 - 4y + 4y^2 - 8y +12y -24
<u>Statement </u> <u>Reason</u>
1. AB = x + 16 1. Given
BC = 4x + 11
AC = 77
2. AB + BC = AC 2. Segment Addition Postulate
3. x + 16 + 4x + 11 = 77 3. Substitution Property
4. 5x + 27 = 77 4. Simplification <em>(added like terms)</em>
5. 5x = 50 5. Subtraction Property of Equality
6. x = 10 6. Division Property of Equality
7. AB = 10 + 16 7. Substitution Property
8. AB = 26 8. Simplification <em>(added like terms)</em>
Yes, it gets flipped if you’re dividing by a negative :)
4.068 is the answer to it
