The coordinates of a point on a coordinate grid are (−3, 7). The point is reflected across the x-axis to obtain a new point. The coordinates of the reflected point are I think it is B
A (−3, −7)
B (3, −7)
C (−3, 7)
D (3, 7)

If f(x)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

If a 36 inch yardstick casts a 21 foot shadow, how tall is a building whose shadow is 168 feet? what is the scale factor

Does the construction demonstrate how to copy an angle correctly using technology a) yes the distance between points a and f was used to create circle h b) yes the distance between points f and g was used to create circle h c) no the distance between points a and f was used to create circle h d) no the distance between points f and g was used to create circle h
