Step-by-step explanation:
||x-5|+2|≤3
-3 ≤ (|x-5| +2) ≤ 3
-5 ≤ |x-5| ≤ 1
|x-5| ≥ -5 => not required
|x-5| ≤ 1
-1 ≤ x-5 ≤ 1
4 ≤ x ≤ 6
the Solutions:
{4≤ x ≤ 6}
This question is a little vague..Please rephrase your question :D
-8x+14≥60 or -4x+50<58
-8x≥46 or -4x<8
x≤ -23/4 or x>-2
A is correct.
the exponential function f(x) =
he invest $1000 for 5, 10, 15 years
5 years,
To find the amount of money he have , we plug in 5 for x and find out f(5)
f(x) =
f(5) =
= 1762.34
The amount of money he have after 5 years is 1762.34
10 years,
To find the amount of money he have , we plug in 10 for x and find out f(10)
f(10) =
= 3105.85
The amount of money he have after 10 years is 3105.85
15 years,
To find the amount of money he have , we plug in 15 for x and find out f(15)
f(15) =
= 5473.57
The amount of money he have after 15 years is 5473.57
f(5) = 1762.34
f(10) = 3105.85
f(15) = 5473.57
Every mile is 5,280 feet, so all you have to do is use this equation. 5,280 * 2.5
