Answer:
(0, 3 ), (5, 0), (10, -3), (15, -6)
Step-by-step explanation:
3x − 5y = 15
-5y = 3x + 15
y =
Point 1: (0, 3 )
y = -3/5(0) + 3
y = 0 + 3
y = 3
Validate:
3 = -3/5(0) + 3
3 = 3
Point 2: (5, 0)
y = -3/5(5) + 3
y = -3 + 3
y = 0
Validate:
0 = -3/5(5) + 3
0 = 0
Point 3: (10, -3)
y = -3/5(10) + 3
y = -6 + 3
y = -3
Validate:
-3 = -3/5(10) + 3
-3 = -3
Point 4: (15, -6)
y = -3/5(15) + 3
y = -9 + 3
y = -6
Validate:
-6 = -3/5(15) + 3
-6 = -6
Answer:
The fraction is .
Step-by-step explanation:
Eduardo Is thinking of a non-unit fraction with a single-digit denominator.
Assuming the fraction to be .
When Eduardo multiplies his fraction by 5 he gets a mixed number and when he multiplies his fraction by 3 he can simplify the answer.
Therefore, the fraction chosen by Eduardo will be , where x is between 5 and 3.
So, the fraction is .
Again, when he multiplies his fraction by 4 he gets which is a whole number. (Answer)
