Answer:
x = $3, or x = $11
Step-by-step explanation:
The equation given is
where
- P(x) is the profit, and
- x is the app price
<u>We want app prices (x's) when profit (P(x)) is 0, so plugging in into the equation:</u>
<em>It means (x-3) = 0 OR (x-11) = 0</em>
So, x = 3, or 11
<span>x=3y-8
3x-4y=-9
We are told that:
</span>x=3y-8
So replace x in 3x-4y=-9 with x=3y-8 like so:
3(3y-8)-4y=-9
Start by distributing the 3:
Now you have:
Combine like terms, now you have:
add 24 to both sides
Now you have:
Divide both sides by 5 to get:
y=3
Now that you know y=3 plug it into:
x=3y-8
x=3(3)-8
x=1
Final answer:
(1,3)
3x-4y=-9
We are told that:
</span>x=3y-8
So replace x in 3x-4y=-9 with x=3y-8 like so:
3(3y-8)-4y=-9
Start by distributing the 3:
Now you have:
Combine like terms, now you have:
add 24 to both sides
Now you have:
Divide both sides by 5 to get:
y=3
Now that you know y=3 plug it into:
x=3y-8
x=3(3)-8
x=1
Final answer:
(1,3)
