Answer:
<u>Missing reason/statements:</u>
- R1, R2, R3 - Given
- S4. ∠1 ≅ ∠3
- R4. Transitive property
- R5. Definition of congruence
- S6. m∠1 = 120°
- R6. Substitution
Answer= Y=-5/3x+7
First substitute (3,2) into the equation y=-5/3x +b which gives you 2=-5/3x+b. Solve for b, then put the equation into slope-intercept form.
D=dog's weight
c=cat's weight
d=7c
d+c=72
sub 7c for d
7c+c=72
8c=72
divide both sides by 8
c=9
d=7c
d=7(9)
d=63
dog=63lb
