Step-by-step explanation:
a) <em><u>Given</u></em><em><u>, </u></em>
Total marks in English = 90
Marks scored by James = 60
<em><u>Therefore</u></em><em><u>, </u></em>
Percentage of marks scored
= <em><u>66.67% (approx. )</u></em>
<em><u>Then</u></em><em><u>,</u></em>
Total marks in Science = 150
Marks scored by James = 78
<em><u>Therefore</u></em><em><u>, </u></em>
Percentage of marks scored
= <em><u>52%</u></em>
<em><u>At</u></em><em><u> </u></em><em><u>last</u></em><em><u>,</u></em>
Total marks in Maths = 120
Marks scored by James = 75
<em><u>Therefore</u></em><em><u>, </u></em>
Percentage of marks scored
= <em><u>62.50%</u></em>
b) In <em><u>English test </u></em> James scored highest percentage.
Answer:
A. Y = -6X + 9
Step-by-step explanation:
Solving for y, we can find the slope of the given line. It is the coefficient of x, 1/6.
-12y = -2x -1
y = 1/6x +1/12
The perpendicular line will have a slope that is the negative reciprocal of this:
m = -1/(1/6) = -6
The y-intercept will be the y-value corresponding to x=0. That value is b=9, given to us by the point the line is to go through. So, we have the slope-intercept form ...
y = mx + b
y = -6x + 9
