Hey there!
-7x + 21 > -14
SUBTRACT 21 to BOTH SIDES
-7x + 21 - 21 > -14 - 21
SIMPLIFY IT!
NEW EQUATION: -7x > -35
DIVIDE -7 to BOTH SIDES
-7x/-7 > -35/-7
SIMPLIFY IT!
x < 5
Therefore, your answer is: x < 5
Good luck on your assignment & enjoy your day!

The relationship between the percentage of frozen citrus crop, and the cost of box of oranges is an illustration of a linear function.
<em />
Given that:
<u>Input and Output quantity</u>
The input quantity is the <em>percentage of frozen citrus crop</em>, while the output quantity is the <em>cost of box of oranges</em>
<u>Linear Function</u>
The given parameters can be written as:
Calculate the slope (m)
So, we have:
The equation is then calculated using:
So, we have:
So, the function is:
<u>The domain and the range</u>
The domain is the <em>possible input value (i.e. possible values of P).</em>
Because P is a percentage, its possible values are 0% to 100%.
Hence, the domain of the function is:
The range is the <em>possible output value (i.e. possible values of c).</em>
When P = 0% and 100%
Hence, the range of the function is:
<u>The meaning of </u><u />
is an inverse equation, where 12 represents the <em>cost of box of oranges.</em>
So, represents the percentage of frozen citrus crop, when the cost is $12.
<u>The inverse formula</u>
We have:
Make P the subject
Divide by 22.9
So, the inverse function is:
<em>This is used to calculate the percentage of frozen citrus crop, when the cost is known.</em>
<em />
Substitute 12 for c
