Answer:
The answer is below
Step-by-step explanation:
A) i)
For Anna initially, she has $0 from making 0 envelopes. After making 400 envelopes she has $20. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (400, 20). Using the equation of a line:
The table is:
x: 200 400 600 800 1000
y: 10 20 30 40 50
ii)
For Jason initially, he has $0 from making 0 envelopes. For every 250 envelopes he has $10. Let x represent the number of envelopes and y the earnings. Hence this can be represented by the points (0, 0) and (250, 10). Using the equation of a line:
The table is:
x: 200 400 600 800 1000
y: 8 16 24 32 40
The graph is plotted using geogebra online graphing
Answer:
No solution
Explanation:
3x - 2y = 7
Y=1.5x+5
3x - 2y = 7
-1.5x + y = 5
3x - 2y = 7
2(-1.5x + y = 5)
3x - 2y = 7
-3x + 2y = 10
0 = 17
This is false, which means that there are no solutions.
Hope that helps!
