If IM is reflected across the x-axis and then translated along the vector <4, 1>, in
taurus [48]

Answer:

Final image L"M" will lie in the fourth quadrant.

Step-by-step explanation:

Coordinates of the ends of segment LM,

L  → (-3, 4)

M → (-3, 2)

Rule to reflect a point across x-axis is,

(x, y) → (x, -y)

By this rule, coordinates of the image point of L and M will be,

L(-3, 4) → L'(-3, -4)

M(-3, 2) → M'(-3, -2)

Further these image points are translated along the vector <4, 1>

Rule for this translation will be,

(x, y) → (x + 4, y + 1)

Now the image points of the points L' and M' will be,

L'(-3, -4) → L"(-3 + 4, -4 + 1)

             → L"(1, -3)

M'(-3, -2) → M"(-3 + 4, -2 + 1)

              → M"(1, -1)

Therefore, final image L"M" will lie in the fourth quadrant.

How many solutions does 5x - 1 = 10x - 4 - 5x + 3 have?
inn [45]

Answer:

Step-by-step explanation:

Simplifying

5x + -1 = 10x + -4 + -5x + 3

Reorder the terms:

-1 + 5x = 10x + -4 + -5x + 3

Reorder the terms:

-1 + 5x = -4 + 3 + 10x + -5x

Combine like terms: -4 + 3 = -1

-1 + 5x = -1 + 10x + -5x

Combine like terms: 10x + -5x = 5x

-1 + 5x = -1 + 5x

Add '1' to each side of the equation.

-1 + 1 + 5x = -1 + 1 + 5x

Combine like terms: -1 + 1 = 0

0 + 5x = -1 + 1 + 5x

5x = -1 + 1 + 5x

Combine like terms: -1 + 1 = 0

5x = 0 + 5x

5x = 5x

Add '-5x' to each side of the equation.

5x + -5x = 5x + -5x

Combine like terms: 5x + -5x = 0

0 = 5x + -5x

Combine like terms: 5x + -5x = 0

0 = 0

Solving

0 = 0

Couldn't find a variable to solve for.

This equation is an identity, all real numbers are solutions.
