First u have to factor the expression

2(9-(x+(x-5))x 8 - 2 x 28 - 2 x 28 - x)

next you have to remove the parenthesis and multiply

2(9 -(x + x - 5) x 8 - 2 x 28 - 2 x 28 - x) that's -2 x 28

2(9 -( x+ x - 5) x 8 - 56 - 2 x 28 - x)

 2(9 -( x + x -5) x 8 -56 -56 - x)

Check like terms

2(9 -(2x-5) x 8 -56 -56 - x)

multiply by 8

2(9 - (16x - 40) -56 -56 - x)

remove parenthesis

2(9 - 16x + 40 -56 -56 - x)

calculate  and collect like terms

2( -63 - 16x - x)

collect the like terms

2( -63 -17x)

your answer is: 2(-63 - 17x)

Does the point (1, –9) satisfy the equation y = 3x − 6?
Tju [1.3M]

Answer:

No.

Step-by-step explanation:

Well, is the points (1, -9) does satisfy the equation y = 3x - 6. Then, substituting the values of x, and, y, into the equation y = 3x - 6,  we should get a true equation.

y = 3x - 6

-9 = 3 * 1 - 6

-9 = 3 - 6

-9 = -3.

So, the points (1, -9) does not satisfy the equation y = 3x - 6.
