Answer:
See the attachment.
Step-by-step explanation:
The approach is to take advantage of the definition of a perpendicular bisector to show the base lengths and right angles are congruent, then use SAS with the second side being CD (congruent to itself). It's mainly a matter of deciding what the various reasons are called.
It seems the goal is to show that AC = BC as marked.
Solve the inequality for x:
5x - 3 ≤ 7x +7
Subtract 7x from each side:
-2x -3 ≤ 7
Add 3 to each side:
-2x ≤ 10
Divide both sides by -2, also when dividing both sides of an inequality you flip the direction of the inequality sign:
x ≥ -5
The dot will be on -5, because the inequality includes equal to, the dot is solid and is greater than, the arrow will point to the right.
The correct answer is D.
Answer:
87
Step-by-step explanation:
common difference = d = 2
an = a1 + (n-1)*d
a43 = 3 + 42*2 = 87

Well the answer would be 12.5. I hoped that this helped. :)
