Answer:
B. 2x – 1 = 13 and x = 7
Step-by-step explanation:
We are given 4 equations and a solution for each. We have to tell which of the given solution satisfies the given equation.
Option A.
2x -1 = 13 and x = 6
Using this value in the equation, we get:
2(6) -1 = 13
12 - 1 = 13
11 = 13, which is not true. Hence this option is not valid
Option B.
2x - 1 = 13 and x = 7
Using the value in the equation, we get:
2(7) - 1 =13
14 - 1 =13
13 = 13, which is true. Hence this option is valid.
Option C.
2x + 1 =13 and x = 7
Using the value in the equation, we get:
2(7) + 1 = 13
15 = 13, which is not true. So this option is not valid
Option D.
2x - 1 = 13 and x = 11
Using this value in the equation, we get:
2(11) - 1 = 13
21 = 13, which is not true. Hence this option is not valid.
Answer:
2. \overline{AX}\cong \overline{BX}AX≅BX
3. PX \perp ABPX⊥AB - definition of perpendicular
4. \angle PXA \cong \angle PXB∠PXA≅∠PXB - all right angles are congruent
6. \triangle AXP\cong \triangle BXP△AXP≅△BXP
7. \overline{PA} \cong \overline{PB}PA≅PB
Answer:
A
Step-by-step explanation:
If the image reflects across the x axis, the x stays the same but y flips:
(-7, 6) across x axis is (-7, -6) so it is A
could you just show me the picture more better then mayebi can help you
Explain what you need help on i dont really understand
