Answer: The answer is (A)
and (C)
Step-by-step explanation: We are given a graph with a point A having co-ordinates (3, 4) and origin O(0, 0). We are to find the slope and equation of line OA.
Since O(0, 0) and A(3, 4) are two points on the line OA, so its slope will be

And the equation of the line will be

Thus, the correct options are (A) and (C).
2x^2 + 3x + 8 = 0
Answer: B) -3 + I √55 over 4.
Answer:
There are 40 total questions on his text.
Step-by-step explanation:
To find this, divide the number of questions he got right by the percentage of the total they represent.
32/80% = 40
4 [5(12+3)-2]-7
4 [5 (15)-2]-7
4 [75-2]-7
4 [73] -7
292-7
