The answer is (-2, 10) because when reflecting over the x, change the sign of y. When reflecting over the y, change the sign of x.
Well combine:
2x + 3x + x + 60 = 180
combine like terms:
6x + 60 =180
then move the 60:
6x = -120
now divide both sides by 6:
x= -20
i hope this helped! :)
You have to divided 11 by 2 in order to get the radius
And you’ll get 5.5
r=5.5
h=12
Your formula is (1/3)(pi)(r^2)(h)
Simplifying the given expression, it is found that Curtis is correct.
<h3>How to simplify the expression?</h3>
The expression to be simplified is given by:
[4(10) - 3²] + 6(4)
The non-related operations can be solved first, hence:
[4(10) - 3²] + 6(4) = [40 - 9] + 24
For the square, we have to consider that:
- For -x², the negative is not part of the square, hence the result is negative, as - x*x = -x².
- For (-x)², the negative is part of the square, hence the result is positive, as (-x)*(-x) = x².
The first bullet point is the reason that -3² = 9. Then, the simplified expression is completed as follows:
[40 - 9] + 24 = 31 + 24 = 55.
Which means that Curtis is correct.
