Answer:
A
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
Under a rotation about the origin of 90°
a point (x, y ) → (- y, x )
Under a reflection in the y- axis
a point (x, y ) → (- x, y )
Under a rotation of 180°
a point (x, y ) → (- x. - y )
Here A(3, - 5 ) → A'(3, 5 ) → A
6/3 I think so try c and if it’s not I’m not sure
:)
-12 = 12 ....this is incorrect...meaning no solutions
**
if it ended in :
x = a number, or y = a number...means there is 1 solution
-12 = 12....incorrect answer, means there is no solutions
2 = 2 or -4 = -4....correct answer, but not variable...means infinite solutions
x = 1 and x = -1
Next time, please separate the equations with a comma or semicolon. Thanks.
We can substitute 4x for y in the quadratic equation x^2 + y^2=17:
x² + (4x)²=17.
Then x² + 16x² = 17, or
17x² = 17, or x² = 1. There are two solutions: x = 1 and x = -1.
