When we reflect a point across y=x, the x and y coordinates switch out , that is (x,y) becomes (y,x) . SO for point (1,2), on reflection across y=x, (1,2) becomes (2,1) . And when we do reflection across y=-x, (x,y) becomes (-y,-x). Therefore point (2,1) on reflection across y=-x becomes(-1,-2) .
So the final answer is (-1,-2) .
Answer:
A. y = 3x - 8
Step-by-step explanation:
y = 3x - 4
This equation is in the form
y= mx+b where the slope is m
The slope is 3
We are looking for an equation with slope 3
A. y = 3x - 8 yes
B. y = -3x - 3 no -3
C. y = -3x - 9 no -3
D. y = -3x - 15 no -3

The correct answer is
Step-by-step explanation:
Snow cone holders are sold in sleeves of 50.
The cones have a slant height (l) of 5 inches and a radius (r) of 3 inches.
Surface area of each cone holder = π × r × l = π × 15 = 15π square inches.
Surface area of all 50 cones in the sleeve = 15π × 50 = 750π = 2357.143 square inches.
Thus 2357.143 square inches pf paper would be necessary for each sleeve each having 50 cone holders.
(x-2) + (x-1) + x + (x+1) + (x-2) + (x+3) = 447
6x + 3 = 447
6x = 447 - 3
6x = 444
x = 444/6
x = 74
