Evaluate -6-2x when x=-4

Mathematics
1 answer:
ad-work [718]3 years ago
8 0

Answer:

2

Step-by-step explanation:

Given -6-2x where x=-4, substitute x=-4 to find the value of the given equation.

Substituting x=-4:

-6-2(-4)

Multiply -2\cdot -4:

-6+8

Combine like terms:

-6+8=\boxed{2}

Therefore, the value of -6-2x when x=-4 is \boxed{2}.

The answer is 2,2

as 3*2 - 2 = 4
ans 2*2 +2 = 4 

So it satisfies both eqautions

Can I get some help, it is due in 15 minutes and I need help. Thanks, any help appreciated
koban [17]

Well, I'm way past the 15 min mark, but here's how to do the question.


With this, you will need to use the distance formula, \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}, on XY, YZ, and ZX.



XY: \sqrt{(3-1)^2+(1-6)^2}


Firstly, solve inside the parentheses: \sqrt{(2)^2+(-5)^2}


Next, solve the exponents: \sqrt{4+25}


Next, solve the addition, and XY's distance will be √29



(The process is the same with the other 2 sides, so I'll go through them real quickly)


YZ:

\sqrt{(6-3)^2+(3-1)^2}\\ \sqrt{(3)^2+(2)^2}\\ \sqrt{9+4}\\ \sqrt{13}



ZX:

\sqrt{(1-6)^2+(6-3)^2}\\ \sqrt{(-5)^2+(3)^2}\\ \sqrt{25+9}\\ \sqrt{34}



Now that we got the 3 sides, we can add them up: \sqrt{29}+\sqrt{13} +\sqrt{34} =14.8


In short, your answer is 14.8, or the second option.
