A solution means that it will make the statement true. Let substitute this in:

y = -2x
-4 = -2(1)
-4 = -2

-4 obviously isn't equal to -2, so it is not a solution to the equation.

Hope this helps!

No it is not, the solution would need to be (2,-4) in order to satisfy the equation y = -2x -- like so -4 = -2(2)

-4 = -4, otherwise the equation won't be satisfied.

What is the answer for<br> -4.8n=13
Shtirlitz [24]

[] Answer []

\boxed{N \ = \ -\frac{65}{24} }

[] Explanation []

-4.8n = 13

====================

Multiply Both Sides By 10:

-4.8n * 10 = 13 * 10

Refine:

-48n = 30

Divide Both Sides By -48:

\frac{-48n}{-48} = \frac{130}{-48}

Simplify:

N = -\frac{65}{24}

\boxed{[] \ Eclipsed \ []}

Exterior angle theorem <br> what is the value of u? I’m willing to give brainlist!!
KengaRu [80]
Answer: 45

Explanation: two angles that form a Line always equal 180 degrees, so we start with the equation 180-u+47, which is the measure of the missing interior angle measure. All of the angles inside of a triangle also equal 180 degrees, so we can set up this equation to find U:
u-18+u+(180-u+47)=180
We can start to simplify by first simplifying what’s inside the parenthesis:
u-18+u+153-u=180
Then you solve the equation to get
U=45 degrees
