Answer:

Step-by-step explanation:

Step 1: Write equation

x² - 8x = 3

Step 2: Solve for x

Complete the Square: x² - 8x + 16 = 3 + 16
Factor: (x - 4)² = 19
Square root both sides: x - 4 = ±√19
Add 4 to both sides: x = 4 ± √19

Given A(3, 4), B(4, 3) and C(2, 1), what are the coordinates of C', the image of C under a rotation of 90 degrees about the orig

Aleks [24]

Given:

The coordinates of the points A, B and C are (3,4), (4,3) and (2,1)

The points are rotated 90° about the origin.

We need to determine the coordinates of the point C'.

Coordinates of the point C':

The general rule to rotate the point 90° about the origin is given by

$(x, y) \Rightarrow(-y, x)$

Substituting the coordinates of the point C in the above formula, we get;

$(2, 1) \Rightarrow(-1, 2)$

Therefore, the coordinates of the point C' is (-1,2)

For all values of x and y, which expression is equivalent to 8x + 6y? A) 2(4x + 3y) B) 2x + 3y C) 3(4x + 2y) D) 4(2x + 3y)

Reika [66]

The answer would be 2(4x + 3y) cause the 2 gets multiplied by the numbers in the parentheses so 2x4x = 8x and 2x 3y = 6y
