Answer:
- proportional: A, B, D, G, I
- non-proportional: C, E, F, H
Step-by-step explanation:
Any relation with a non-zero initial value or y-intercept is non-proportional. Any relation that has a constant ratio between output and input is proportional.
C has an initial value of 7
E has a y-intercept of -3
F has an initial value of 2.00
H has an initial value of 5
All of these are non-proportional. The remainder are proportional.
Yess, such fun so
q=number of quarter
n=number of nickles
q+n=63
9.15=915 cents
25 cents=1 q
5 cents=1 n so
915=25q+5n
915=5(5q+n)
divide by 5
183=5q+n
we also have q+n=63
subtract q from both sides
n=63-q
subsitute 63-q for n in second equation
183=5q+63-q
add like terms
183=4q+63
subtract 63 from both sides
120=4q
divdie by 4
30=q
there were 30 quarters
subsitute
63=30+n
subtract 30
33=n
30 quarters
33 nicles
Answer:
it is d because they dont have enuff info :)
Answer:
69
Step-by-step explanation:
first 135
second 135 - 20% = 135 - 27 = 108
third 108 - 20% = 108 - 21.6 = 86.4
fourth 86.4 -20% = 86.4 -17.28= 69.12
rounded 69

How to Calculate Midpoint?
The x-coordinate of the midpoint M of the segment 
is the arithmetic mean of the x-coordinates of the endpoints of the segment . Similarly, the y-coordinate of the midpoint M of the segment is the arithmetic mean of the y-coordinates of the endpoints of the segment .
