Given: AB = 3x + 2; BC = 4x + 8; AC = 38 Prove: x = 4

Statements Reason
1. AB = 3x + 2; BC = 4x + 8;

AC = 38 1. Given
2. AB + BC = AC 2. Segment Addition Postulate
3. 3x + 2 + 4x + 8 = 38 3. Substitution Property of Equality
4. 7x + 10 = 38 4. Combining Like Terms
5. 7x = 28 5. Addition Property of Equality
6. x = 4 6. Division Property of Equality

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
