When you reflect something across the y axis, you take the opposite of all the x axis coordinates (the point 'on the other side of the number line,' and when they add together, they make 0). Now we can solve for each of the points.
Reflected across the y axis, we have to take the opposite of -2 and that's 2. That means that P becomes P'(2, -4).
Reflected across the y axis, we have to take the opposite of -3, and that's 3. That means that Q becomes Q'(3, -1).
Reflected across the y axis, we have to take the opposite of -4 and that's 4. That means that R becomes R'(4, -4)
Means per hundred hope its right
In this question, <span>q is the number of buggies the company can sell in a month if the price is $p per buggy. The revenue should be number of buggies sold(q) multiplied by the price(p). The equation would be:
revenue= p * q
revenue= p * (-4p + 616)= -4p^2 + 616p
The maximum revenue should be in the peak of the graph. The calculation would be:
</span>-4p^2 + 616p
-4*2 p^2-1 + 616*1 p^1-1=0
<span>-8p + 616=0
8p= 616
p=77
Put p=77 in the revenue equation would result
</span>revenue= -4p^2 + 616p
revenue= -4(77^2) + 616(77) = -23716 + 47432= $23716
Rearrange the equation
(3a^2–7a^2-3a^4)+(4a^2-a^4-4a)
(-3a^4 +3a^2 - 7a^2) + (-a^4 + 4a^2 - 4a)
-4a^4 - 4a
-4a ( a^3 + 1)
