7x - 1 + 6x - 1 = 180
add the x’s, add the numbers
13x - 2 = 180
add 2 to 180
13x = 182
divide 182 by 13
x = 14
Answer:
C
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ), thus
A(3, 4 ) → A'(- 3, 4 )
Since the point A and it's reflection lie on a horizontal line then
distance between = | 3 + 3 | = | 6 | = 6
Answer:
uh take or add x plus the y then z =5
