if the graph is NOT a linear function, then the two variables are NOT directly proportional
Answer:
16.75%
Step-by-step explanation:
find the difference:
23000 - 19700 = 3300
no divide 3300 by 19700 to get the percent
3300 / 19700 = 0.1675
move decimal twice for percent
16.75%
The system. only really just possibly. have one solution
Answer: FALSE .
____________________________________________
For two (2) angles to be supplementary, they must add up to 180° ;
and the two angles given — 98° and 72° — add up to 170°.
{Note: 98 + 72 = 170 — NOT "180" ; and as such are NOT supplementary.}.

Answer:
84.85cm
Step-by-step explanation:
Let the sides of the square be x
The perimeter of the square = 4x
Get x using the pythagoras theorem
x^2 + x^2 = 30^2
2x^2 = 900
x^2 = 450
x = 21.21cm
Perimeter of the plate = 4(21.21)
Perimeter of the plate = 84.85cm
