Answer:
(-1, 3)
Step-by-step explanation:
The given equation is 2x + y = 5.
Test whether (-1, 3) is a solution. To do this, substitute -1 for x and 3 for y. Does 2(-1) + 3 = 5? No, it does not. So this could be the correct answer choice.
Test whether (6, -7) is a solution. Is 2(6) - 7 = 5 true? Yes, it is. So this is not a correct choice.
Test whether (3, -1) is a solution. Is 2(3) -1 = 5? Yes, it is. So this is not a correct choice.
Summary: The only answer choice that does NOT satisfy the given equation is the first one: (-1, 3).
Answer:
3.1% increase
Step-by-step explanation:
Diameter1=25cm
Radius1=12.5cm
Circumference1=2x22/7x12.5
Diameter2=25.8cm
Radius2=12.9cm
Circumference2=2x22/7x12.9
% increase =Circumference2-Circumference1/Circumference2 x 100%= 2x22/7x12.9-2x22/7x12.5 / 2x22/7x12.9 x100%
12.9-12.5/12.9 x 100%
0.4/12.9 x 100%
4/129 x 100%
3.1%
