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:
The value of x are all real number on x-axis the number that falls under x
example of the value of x are in this equation
y=2+5x
2x+6y=60
to find x
let make the first one equation 1 and the second equation 2
now, put equation 1 in equation 2
2x+6(2+5x)=92
open the by multiplying every thing in the bracket by 6
2x+12+30x=92
combine the like terms
2x+30x=69212
32x=80
now divide via by 32
32x/32=80/32
x=5/2
1/4+ (-3/4) = -0.5
-4 1/2 +2= -2.5
-8+ (-11/8)= -9.125
Answer: Listen u are right on 1 and 2 don’t know about 3 but Um the website is incorrect u had 1 and 2 correct so I don’t know
Step-by-step explanation:
hope it will help u......
