Question

1 point Sally is solving the linear equation 13+ 4x - 9 = 7x + 7-3x. Her final two steps are: 4 + 4x = 4x +7 Select the statement that correctly interprets Sally's solution O The solution is x = 0. O The solution is the ordered pair ( 4,7). O There is no solution since 4=7 is a false statement. There are infinitely many solutions since 4=7 is a false statement. 1 point Lines j and k are shown in the diagram below. Some of the angles created when the lines are 2 1 j

Answer 1

as the sides of two triangles are the same. so they are congruent

also one triangle is the reflection of the other triangle, and the reflection is about x axis ( Horizontal axis)

thus, the answer is option A
