Answer:
so we substitute in K(x) into the equation K(x)=6x-12
which gets us: 18=6x-12
6x=30
x=5
Answer:
Gradient of the line with points (-4,1)&(3,-2) is
(-2-1)÷(3-(-4))=-3/7
Then the equation of that^ line is
Y-1=-3/7(x-(-4))--->y=-3/7x-5/7
Since this^ line is perpendicular to the line you are looking for.the gradient of the line you are looking for is -1÷(-3/7)=7/3
The equation of the line you are looking for is
Y-1=7/3(x-2)--->y=7/3x-11/3
[Cause the line you are looking for passes through the point (2,1) and you found the gradient of this line]
The point (0,5) with a slope of 1/2 is
y=1/2x+5
You would have to have 20 minutes of studying per hour of class time. This means that 60 times 2=120. 120-90=30. 30 minutes is half an hour. So you would do 20 divided by 2 since u are adding another half hour to studying. You would add 60 and 10 to get 70 as your answer I think. I hope this helps and is correct :)
