Answer:
Step-by-step explanation:
Start with:
Distribute the 
into 
:
Combine like terms:
Add to both sides of the equation:
Subtract 
from both sides of the equation:
Divide both sides of the equation by the coefficient of 
, which is 
:
or
A) $27,000.00 - $5,000.00 =$22,000.00

Answer:
rate change: -8
Equation: y = 232 -8x
After 5 hours: 192
Step-by-step explanation:
8 are destroyed every hour, so there are 8 less every hour, so the rate of change is -8
It starts with 232 and loses 8 per hour, so the formula is
y = 232 - 8x
After 5 hours:
y = 232 - 8(5)
y = 232 - 40
y = 192
Answer:
6
Step-by-step explanation:
Her profit will increase be 6 dollars.
x = 1
y = 45(1)
y = 45
Answer:
x = 3
Step-by-step explanation:
The pair of angles given are alternate angles (they form a 'Z' shape). Alternate angles are always equal to each other. From this, we can get the equation:
14x - 13 = 8x + 5
Collect like terms,
6x - 13 = 5
6x = 18
x = 3
