If the problem is X-71=0, Then X=71, but if you intentionally put the space between the 7 and 1, then I'm not certain what operation is happening between them.

8+-1= 7 x=-1

x = 1/2 [ 1 Â± i sqrt(7) ]

7r2+48r-7 = (7x-1)(x+7) when factored

-5

y = x - 7 or, y = 1*x - 7 so that the slope is 1.

x = 1/2 [ 1 Â± i sqrt(7) ]

It could be either, depending on what x equals. If x = 9, 8 will solve the first one. If x = 1, 8 will solve the second one.

2x + 7 = 1 Therefore, 2x = -6 x = -6/2 x = -3

y = x - 7 or, y = 1*x - 7 so that the slope is 1.

y=7+x =x=7-x

A quadratic equation. If you wish to solve for x, you can do so as follows: -x2 + 6x + 7 = 0 x2 - 6x - 7 = 0 (x - 7)(x + 1) = 0 x ∈ {-1, 7}

wel i cant explain how i did this but the answer is -1/7
