Parallel lines are always straight so find the coordinates and then do y2-y1 over x2-x1 and it will be 0

Anyone know how to solve this?

I think the answer is 90 or 15? I don’t really understand this, so don’t trust me on this. I’m attempting this.

Simplify the expression

Darina [25.2K]

The answer is D because the radical is cubed which means you have to break down whatever is in the inside and group it into 3s and take is out. Ex. 81 can be split into 9 and 9 and further 3x3x3x3. from here you can take out 3 3s and put them on the outside and have one 3 left in the inside.

HELP ASAP ITS TIMED

Answer:

x + 10 = x² + 1

(third option listed)

Step-by-step explanation:

assuming that you meant: $\sqrt{x+10-1}=x$ , because otherwise there would be no equivalent relationships,

(goal: isolate x on one side of the equation whilst having x on the other side of the equation also, like the equation in the question)*

x + 10 = x² + 1

-1 -1

x + 10 - 1 = x²

$\sqrt{x+10-1} =\sqrt{x^2}$ [find √ of both sides to isolate x]

$\sqrt{x+10-1} =x$ (equation in problem)

{note: there's no reason to not simplify the equation to $\sqrt{x+ 9$ , but the question leaves the equation that way, so I didn't simplify it either}
