Answer:

y=-1 and x=-1

Step-by-step explanation:

10x/-10y=-1 y=-1 same with x=-1

here is a different equation

12x(-1)=(144/12y)=x and y

x=-y

y=-x

-y=-1y because if there is no variable it is 1 or -1 depending if its a - Symbol

same with -x=-1x

If f ( 4 ) = − 2 , write an ordered pair that must be on the graph of y = f ( x + 4 ) + 1
AlekseyPX

We have been given that

y = f ( x + 4 ) + 1\\
\\
f(4)=-2

Now, we need to find an ordered pair that must be on the graph of

y = f ( x + 4 ) + 1

On substituting x=0 in the above equation, we get

y = f ( 0 + 4 ) + 1\\
\\
y=f(4)+1\\
\\
\text{On substituting the value of f(4)= -2, we get}\\
\\
y=-2+1\\
y=-1

Therefore, the required ordered pair is given by (0,-1)

A circle has a radius of 5.4 m. what is the exact length of an arc formed by a central angle measuring 60°? enter your answer in
velikii [3]

The length of the arc of the circle with a radius of 5.4 m and the central angle measuring 60° is 5.655 meters.

<h3>What is the Length of an Arc?</h3>

The length of an arc is given by the formula,

\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360}

where

θ is the angle, which arc creates at the centre of the circle in degree.

The length of the arc of the circle with a radius of 5.4 m and the central angle measuring 60° can be written as

\text{Length of the Arc} = 2\pi r \dfrac{\theta}{360}

                            = 2 \times \pi \times 5.4 \times \dfrac{60}{360}\\\\=5.655\rm\ m

Hence, the length of the arc of the circle with a radius of 5.4 m and the central angle measuring 60° is 5.655 meters.
