I'm not 100% sure on the first one but on the second I can help you out. How would you characterise the relationship? All it is, is that the more hours were spent studying, the higher the score will be.
Paul's function. Since the x values are hours of study all you must do is sub 3 for x in the equation giving you y = 8(3) + 40 = 24 + 40 = 64
What does the 40 mean? This in a straight line is the y-int so all its saying is that no matter how much study Paul does, he will at least get 40 marks.
Hope this helped :)

Answer:
the answer to your equation is 2
If you would like to find the values of a, b, and c in the quadratic equation, you can do this using the following steps:
ax^2 + bx + c = 0
-2x^2 + 4x - 3 = 0
a = -2
b = 4
c = -3
The correct result would be <span>a = –2, b = 4, c = – 3.</span>

Answer:
54 square meters
Step-by-step explanation:
Similar figures have corresponding lengths as equal ratios.
Smaller trapezoid's base is given 12 and larger trapezoids base is given 18, so the scale factor is 
<em>this means the lengths of larger is 1.5 times lengths of smaller.</em>
<em />
In terms of area, the scale factor is squared. Hence the scale factor for area is 
<em>this means the area of larger is 2.25 times the area of smaller.</em>
<em />
Now, Let area of smaller trapezoid be x so we can say: 
<em>to nearest square meter, </em><em>x = 54 meters squared</em>
