For each value of u, determine whether it is a solution to - 23 = 5x + 7

Be careful. A solution implies there (maybe) is only one solution.

We have

-23=5u+7 \\-30=5u \\u=-6

So yes u is a solution.

(pls also provide an explanation for how i do this)
Marizza181 [45]

Answer:

slope = \frac{3}{4}

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (5, 3 ) and (x₂, y₂ ) = (9, 6 )

m = \frac{6-3}{9-5} = \frac{3}{4}

The point (5,4) is rotated 180° clockwise
zmey [24]

Answer:  (-5,-4)

Step-by-step explanation:

I assume that you need the new coordinates of the point after the rotation centered at the origin.

For this exercise it is important to remember the definition of "Rotation".

A Rotation is defined as a transformation which a figure is rotated about a fixed point known as "Center of rotation".

The figure before the transformation is called Pre-Image and the figure obtained after the transformation is called "Image".

The 180 degree rotation about the origin Rule states that:

(x,y) → (-x, -y)

Therefore, knowing that the given point (5,4) is rotated 180 degrees clockwise about the origin, you can conclude that its Image is:

(-5,-4)
