Answer:


Science class had a higher average
Step-by-step explanation:
Given

g(x) table
Solving (a): f(2)
We have:

So:



Solving (b): g(2)
From the given table.

Solving (c): f(4) or g(4); which is greater

So:



For g(4): Notice that in the table of g(x); g(x) increases by 2 when x increases by 1
This means that:

So




<em>Hence, g(4) i.e. Science class is greater</em>
Answer:
Y = 90
X = 52
Step-by-step explanation:
Y is on a straight line. The sum of the angles on a straight line is 180.
The only other angle (that is marked) on this straight line, is a 90 degree one. So, <y + 90 = 180.
<y = 90.
Now <x + 38 = 90
so, x = 52
