Y = -2x + b
Plug in point
1 = -2(-9) + b
1 = 18 + b, b = -17
Solution: y = -2x - 17

Answer:

k= -7

Step-by-step explanation:

multiple both sides of the equation by 56.

16k - 21 = -133

move the constant to the right hand side and change its sign.

16k = -133 + 21

Calculate the sum.

16k= -112

Divide both sides by 16.

k = -7

Solution is K = -7

Part two.

Take away 19.5 from 40 to get your answer.

your answer is then less than forty so it's the symbol <.

I am not entirely sure on this second part I would get someone to double check it as I'm not the best at inequalities and such. If any help is needed with what I done just ask.

Please help me! I will give Brainlylist

Answer:

I would say that they are different because if x - a has a value to the equation then that means a - x will not have the same value because it may be rearranged to a different equation but that doesn't mean that they will have the same value. that explain why x - a and a - x are not the same
