The result of an absolute value operation is never negative. So the smallest that the expression |x+5| can be is 0.
Tacking on "-8" to |x+5| leads to |x+5|-8
The range of this is [-8, infinity) since the smallest |x+5|-8 can be is -8. All I did was subtract 8 from the smallest value of |x+5|
Final Answer: choice C)
Step-by-step explanation:
EZ = $0.15/min...eqn 1
Go = $40 + $0.05/min...eqn 2
let x be no of minutes then combine both eqns...
=> 0.15x = 40 + 0.05x...eqn 3
=> 0.1x = 40
x = 400
thus at 400mins both plans are equal
at 200mins go wit EZ...
total bill = $0.15 × 200 = $30.00

Answer:
Step-by-step explanation:
Given the functions f(x) and g(x), to find you need to substitute into the function g(x):
Now, to find you must substitute into , then you get:
Answer:
x=1
Step-by-step explanation:
9(4–5x)+2=7(6x–7)
Distribute
36 -45x +2 = 42x-49
Combine like terms
-45x +38 = 42x-49
Add 45x to each side
-45x +38 +45x = 42x+45x-49
38 = 87x-49
Add 49 to each side
38+49 = 87x-49+49
87 = 87x
Divide by 87
87/87 = 87x/87
1 =x
