C if you look at the square you can see that b b =bb and not Bb
Answer:
100x − 200y = 600 and x + y = 12
Explanation:You can win the quiz show with 600 points. Remember that correct responses are worth 100 points and incorrect responses are worth -200 points. So, you need your total points from each correct response, x, minus your total points for each incorrect response, y, to equal 600:
100x − 200y = 600.
If you only respond to 12 questions, you need the total number of correct responses, x, plus the total number of incorrect responses, y, to equal 12:
x + y = 12.
Together, these two equations describe one way you can win.
Plants are autotrophs because they carry out photosynthesis and produce food for themselves.
<span>Fungi does not contain chlorophyll or carry out photosynthesis, which is why you can find a lot of fungi in dark places. Fungi takes its nutrients from dead organic matter, which is why you would find fungi on rotten fruits and dead animals.</span>
