Answer:
(a) Line 1
Step-by-step explanation:
The given point is only a solution to the equation for Line 1. This is shown in the attached graph.
__
You can put those values into each equation to see if it is satisfied.
1: -4 +2 = -2 . . . . this equation is satisfied.
2: 3(-4) -(2) = -14 ≠ 2 . . . . this equation is not satisfied
(-4, 2) is a solution to the Line 1 equation only.
<DOC = <AOB
= 91 degrees
<AOD = 180 - <AOB
= 180 - 91
= 89
Column A Column B
<AOD <DOC
89 91
Answer:
x=3/2
Step-by-step explanation:
12-7x+6-5x=0
12x=18
x=18/12=3/2
Verification:
12-7(3/2)+6-5(3/2)=0
Hope, this helps you.
45 new houses...
1/3 were sold......1/3(45) = 45/3 = 15 houses sold.....leaving 45 - 15 = 30 houses left. 1/5 of remaining houses sold....1/5(30) = 30/5 = 6...so 6 more houses were sold.....leaving 30 - 6 = 24 houses
24 houses are left <==
