Answer:
A is correct.
Step-by-step explanation:
From the second sentence , we can deduce that the total number of problems is 29.
Now, x represents the number of problems that award 5 marks, while y represents the number of problems that award 2 marks.
Hence x + y = 29.
There are a total of 100 marks. This mean each x has a mark of 5, so total x marks equal 5x. Also, each y has a mark of 2. total y marks equal 2y. Since total marks equal 100. This mean 5x + 2y = 100 which gives our second equation.
This shows A is correct.

Answer:
x-0 y-.75
Step-by-step explanation:
Logarithms are only able to make an equation linear if it is an exponential function. For example,
can be made linear by taking the natural logarithm of each side, causing it to become
. After some simplifying, you are left with
. You are then able to plot ln(y) vs. x to get a linear fit.
