Hello!
- Move all the x's to the left, using the opposite operation:
- 2x+6x-16≥32
- Now, move all the numbers to the right, using the opposite operation:
- 2x+6x≥32+16
- Combine Like Terms:
- 8x≥48
- Divide both sides by 8:
- x≥6
Final Answer:
x≥6
I hope it helps.
Good luck & enjoy your day!

The exponential function f(x) can represent growth or decay
The value of f(14) is 226.07
<h3>How to determine the value of f(14)?</h3>
The given parameters are:
f(-2) = 25 and f(7) = 85
An exponential function is represented as:
f(x) = ab^x
So, we have:
ab^-2 = 25
Also, we have:
ab^7 = 85
Divide both equations.
This gives
b^9 = 3.4
Take the 9th root of both sides
b = 1.15
Recall that:
ab^7 = 85
This gives
a* 1.15^7 = 85
Solve for a
a = 31.95
So, the exponential function is:
f(x) = 31.95 * 1.15^x
Substitute 14 for x
f(14) = 31.95 * 1.15^14
f(14) = 226.07
Hence, the value of f(14) is 226.07

Answer:
$179.20
Step-by-step explanation:
use the formula retail price = original price + markup
Step One: Convert 28% to a decimal
--> 0.28
Step two: Plug all the numbers into the equation
--> $140 + $140 x 0.28 = $179.20

Answer:
2.50
Step-by-step explanation:
30% of 25 is 7.50 take that away from 25 gives you 17.50 take that away from 20 gives you 2.50
