Answer choices are 2x plus y = -5, 2x - y=5
x+ 2y=-10

y = -(1/2)x - 5 which comes from x + 2y = - 10

Step-by-step explanation:

The question was which equation is equivalent to y = (-1/2)x - 5 I think.

In that case, we need to solve these equations to get an answer.

2x + y = -5 gives

y = - 2x - 5 which is not the answer you want.

2x - y = 5 gives

y  = 5 - 2x    by subtracting 2x from both sides, and this is not the answer.

x + 2y = -10                 Subtract x from both sides.

2y + x - x = -x - 10       Combine on the left.

2y = - x - 10                Divide by 2

2y/2 = -x/2 - 10/2

y = -x/2 - 5                  Answer

80 the answer is 80

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
