Answer:
option ( c ) is correct !!
Step-by-step explanation:
Given equations :-
y = -6x + 9 ________ ( i )
y = -3x + 3 .....( ii )
Equating both i and ii
-6x + 9 = -3x + 3
-6x + 3x = 3-9
-3x = -6
x = -6/-3
x = 2
Also, y = -3x + 3
y = -3(2) + 3
y = -6 + 3
y = -3
So, ( x , y ) = ( 2 , -3 )
So what they are trying to say is that they both have the same y-intercept. Easy!
Make y the subject:
5x - 2y = 3
2y = 5x - 3
y = 2.5x - 1.5
The y-intercept is -1.5.
Make y the subject:
x + y = a
y = -x + a
Therefore, a must be -1.5 !
Answer:

Step-by-step explanation:
Answer:10.3% is the percentage of students who cancelled, but the question is asking for the students who are attending, so let's use 89.7% to make it easier. The proportion would be x over 58 is equal to 89.7% over 100%. ... 52 students actually attend the art class, making this your final answer.
