If the line is linear and passes through the point (0,0) then the function is proportional.
3y = -2x + 6 is linear but does not pass through the point (0,0).
3y = -2x + 6 is nonproportional.
Given expressions:
Area of a rectangle = L W
Area of a triangle = 
Problem;
Create problems using the formula;
Solution:
Problem 1; Find the area of a rectangle whose length is 10cm and the width is half the size of the length?
Given parameters:
Length of rectangle = 10cm
Width of rectangle =
x length =
x 10 = 5cm
So, the area of the rectangle = 10cm x 5cm = 50cm²
2. A triangle with a base length of 30cm and a height of 2cm will have an area of what?
Given parameters:
base length = 30cm
height = 2cm
Solution:
Area of a triangle =
x b x h
Area of a triangle =
x 30 x 2 = 30cm²
The area of the triangle will be 30cm²
Answer:
$6
Step-by-step explanation:
$25 divided by 50 = 50 cents a CD
50 cents = 0.5
Now do,
$12 x 0.5 = $6
$6
16 because two negatives numbers equal a possitive so 16
