<h2>question :</h2>
40. which of the following equation graphs as a vertical parallel to the y-axis?
41. if ΔABC = ΔFGH, then which of the following statements is not necessarily true?
<h2>my answer :</h2>40. the meaning of "vertical parallel to the y-axis" is a line that is perpendicular to the x-axis
then the equation that can be written parallel to the line y is x = a, a is the distance from point 0.
(*the second choice is correct)
41. if ΔABC = ΔFGH, it can be said that the second triangle of the shape is congruous (*in the picture)
(*the second choice is correct)

Answer:
Student can obtain 15 marks by attempting 8 questions.
Step-by-step explanation:
This question is incomplete; complete question is here.
A student taking a test consisting of 10 questions is told that each questions after the first is worth 2 marks more than the preceding question. If the third question of the test is worth 5 marks.What is the maximum score that the student can obtain by attempting 8 questions?
A students when attempts the questions the sequence formed by the scores he gets will be in the form of a, (a + 2), (a + 4), (a + 6)........
Which will be an arithmetic sequence with a common difference = 2
We know explicit formula of an arithmetic sequence is
Where = First term of the sequence
a = first term
n = number of term
d = common difference
It is given that 3rd term of this sequence is 5.
a = 5 - 4 = 1
Explicit formula for the sequence will be
Now if the student attempts 8 questions then from the explicit formula
Therefore, student can obtain 15 marks by attempting 8 questions.
