Answer:
They are taking 12 2 credit courses
The are taking 4 1 credit courses
Step-by-step explanation:
x = 1 credit courses
y = 2 credit courses
The number of courses is 16
x+y = 16
The number of credits is 28 so multiply the course by the number of credits
1x+2y=28
Subtract the first equation from the second equation
x+2y =28
-x-y=-16
-----------------
y = 12
They are taking 12 2 credit courses
We still need to find the 1 credit courses
x+y = 16
x+12= 16
Subtract 12 from each side
x-12-12 = 16-12
x =4
The are taking 4 1 credit courses
Answer:
-1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(4-7)/(8-5)
m=-3/3
m=-1
So you label -20 on the number line. Then you split it into -5 and count much space is in between the <em>'split'.</em>
