Proportion problems
An example is:
y is directly proportional to x such that: y=4 when x = 2;
Derive the equation
For direct proportions, we have:
This gives:
Make k the subject
So:
So, the equation is:
Assume the above question is for inverse proportion
The variation will be:
This gives:
Make k the subject
So, the equation is:
Answer:
A) Neither
Step-by-step explanation:
If two lines have same slope then they are parallel lines
If slope of line1* slope of line 2 = -1
The the two lines are perpendicular
In this question slope of line = 2\7
Slope of line 2 = 7\2
Answer:
Step-by-step explanation:
Part a- it’s the first one 7b+6=96
part b- b= 1.28571428571
5 - 2x=-9
to start, you must isolate the variable. you would subtract 5 from both sides of the eqauation:
-2x = -14
next you must get rid of that -2 so you would divide each side by -2:
x= 7
