Answer:
D.
Step-by-step explanation:
Step 1: Write slope-intercept form
y = mx + b
Step 2: Solve for <em>m</em>
- Subtract b on both sides: y - b = mx
- Divide both sides by x: (y - b)/x = m
- Rewrite: m = (y - b)/x
Answer:
71 %
Step-by-step explanation:
Paper 1 :
65% of 120 = 0.65 X 120 = 78
Paper 2 :
80% of 80 = 0.8 X 80 = 64
Total Percentage:
Add the two scores 78 + 64 = 142
Add the what it was out of 120 + 80 = 200
Use (Score / Total marks available) X 100
(142 / 200) X 100 = 71
19,999 because 5 and up round it up, lower than 5 round it down.
It looks like it might be C
The reason that I said might is because if it is C the second equation should contain -x not x.
