Answer:
x = 0
Step-by-step explanation:
Divide by -2
-2(x - 2)/-2 = 4/-2
x - 2 = - 2
Add 2 to both sides
x - 2 + 2 = - 2 + 2
x = 0
Answer:
Step-by-step explanation:
the original price would be $80.00
50.00*0.08 = 4 50.00-4 = 46.00
46.00 for 25 radios with 4 cash back
30.00*0.15= 4.5 30.00- 4.5 = 25.50
total is 71.50
Note that 125 = 5³. Make use of the factorization of the sum of cubes:
a³ +b³ = (a+b)(a² -ab +b²) . . . . . . a formula worth keeping handy
Then ...
_____
When x=-5, this evaluates to
... (-5)²-5(-5) +25 = 75
