Answer:
5)
<2 = 79°
<1 = 101°
<3 = 101°
6)
x = 5
y = 3
Step-by-step explanation:
5)
<2 = 79°
<1 = <3 = 180 - 79 = 101°
6)
4y - 6 = 2y
2y = 6
y = 3
2x + 4 = x + 9
x = 5
Depreciation = (Cost - Residual)/Useful Life
Cost = $48,000
Residual = $9,000
Useful Life = 15 years
Depreciation = (48,000-9,000)/15
Depreciation = 39,000/15
Depreciation = $2,600
The refrigerator will depreciate at $2,600 a year.
12x - 5y = 2
12x - 12x - 5y = -12x + 2
-5y = -12x + 2
-5 -5
y = 2.4x - 0.4
y - 3 = 2.4(x - 3)
y - 3 = 2.4(x) - 2.4(3)
y - 3 = 2.4x - 7.2
+ 3 + 3
y = 2.4x - 4.2
Answer:
The second answer is in standard form of equation
