<h2>The sine function won't be affected, but the consine function will.</h2>Step-by-step explanation:
First of all, remember that and
. As you can see, the sine function won't be affect by
, because its value is null.
However, the x-intercept of the cosine function depends on the value, because the function is equal to the unit.
On the other hand, the variable won't affect any function, because it would be always zero.
Therefore, the sine function won't be affected, but the consine function will.
Answer:
The inequality 7.50c - 350 ≥ 700 can be used.
Step-by-step explanation:
Given that:
Amount spent on materials = $350
Amount the council needs to earn = $700
Selling price per corsage = $7.50
Number of corsages sold = c
Selling price per corsage * Number of corsages sold - amount spent on materials ≥ amount needs to be earned
Hence,
The inequality 7.50c - 350 ≥ 700 can be used.
