Answer:
4y = -x + 9
Step-by-step explanation:
2y = 8x - 6
Divide through by 2:-
y = 4x -3 so the slope of this line = 4
Slope of the line perpendicular to this = -1/4
So using the point/slope form of an equation of a line and the point (-3,3) we have:-
y - 3 = -1/4(x - -3)
y = -1/4x - 3/4 + 3
y = -1/4 x + 9/4 Multiply through by 4:-
4y = -x + 9
If 100 cats killed 100 mice in 100 days, you can say that each cat killed one mouse the day after the last cat. So, if four cats killed four mice, and we're going of off the same basis that each cat killed one mouse the day after the last cat, then the answer would be 4.
The fact that the first chosen student was a girl is already decided, so there is no need to find the probability of that happening. There are a total of 13+10, or 23 students. A girl was already selected, so that leaves 22 students. The chance that a boy is chosen is 10/22, or 5/11.
There are two solutions to this question, one is positive and the other is negative:
