Answer:

Step-by-step explanation:

A. -4

B. 4

C. no values

Step-by-step explanation:

When x increases by 2, m(x) increases by 1.  So m(x) is linear.  Pick two points to find the slope:

(3 − 2) / (10 − 8) = ½

Use point-slope form to write the equation:

m(x) − 2 = ½ (x − 8)

m(x) − 2 = ½ x − 4

m(x) = ½ x − 2

Part A

h(4) − m(16) = ½ (4 − 2)² − (½ (16) − 2)

h(4) − m(16) = 2 − 6

h(4) − m(16) = -4

Part B

h(0) − m(0) = ½ (0 − 2)² − (½ (0) − 2)

h(0) − m(0) = 2 − (-2)

h(0) − m(0) = 4

Part C

m(x) − h(x)

(½ x − 2) − ½ (x − 2)²

½ x − 2 − ½ (x² − 4x + 4)

½ x − 2 − ½ x² + 2x − 2

-½ x² + 2½ x − 4

Complete the square.

-½ (x² − 5x) − 4

-½ (x² − 5x + 25/4) − 4 + ½ (25/4)

-½ (x − 5/2)² − 7/8

This is always negative, so m(x) is always less than h(x).

Maggie graphed the image of a 90 counterclockwise rotation about vertex A of . Coordinates B and C of are (2, 6) and (4, 3) and
Lemur [1.5K]

Answer:

A(2,2)

Step-by-step explanation:

Let the vertex A has coordinates (x_A,y_A)

Vectors AB and AB' are perpendicular, then

\overrightarrow {AB}=(2-x_A,6-y_A)\\ \\\overrightarrow {AB'}=(-2-x_A,2-y_A)\\ \\\overrightarrow {AB}\perp\overrightarrow {AB'}\Rightarrow \overrightarrow {AB}\cdot \overrightarrow {AB'}=0\Rightarrow (2-x_A)(-2-x_A)+(6-y_A)(2-y_A)=0

Vectors AC and AC' are perpendicular, then

\overrightarrow {AC}=(4-x_A,3-y_A)\\ \\\overrightarrow {AC'}=(1-x_A,4-y_A)\\ \\\overrightarrow {AC}\perp\overrightarrow {AC'}\Rightarrow \overrightarrow {AC}\cdot \overrightarrow {AC'}=0\Rightarrow (4-x_A)(1-x_A)+(3-y_A)(4-y_A)=0

Now, solve the system of two equations:

\left\{\begin{array}{l}(2-x_A)(-2-x_A)+(6-y_A)(2-y_A)=0\\ \\(4-x_A)(1-x_A)+(3-y_A)(4-y_A)=0\end{array}\right.\\ \\\left\{\begin{array}{l}-4-2x_A+2x_A+x_A^2+12-6y_A-2y_A+y^2_A=0\\ \\4-4x_A-x_A+x_A^2+12-3y_A-4y_A+y_A^2=0\end{array}\right.\\ \\\left\{\begin{array}{l}x_A^2+y_A^2-8y_A+8=0\\ \\x_A^2+y_A^2-5x_A-7y_A+16=0\end{array}\right.

Subtract these two equations:

5x_A-y_A-8=0\Rightarrow y_A=5x_A-8

Substitute it into the first equation:

x_A^2+(5x_A-8)^2-8(5x_A-8)+8=0\\ \\x_A^2+25x_A^2-80x_A+64-40x_A+64+8=0\\ \\26x_A^2-120x_A+136=0\\ \\13x_A^2-60x_A+68=0\\ \\D=(-60)^2-4\cdot 13\cdot 68=3600-3536=64\\ \\x_{A_{1,2}}=\dfrac{60\pm8}{2\cdot 13}=\dfrac{34}{13},2

Then

y_{A_{1,2}}=5\cdot \dfrac{34}{13}-8 \text{ or } 5\cdot 2-8\\ \\=\dfrac{66}{13}\text{ or } 2

Rotation by 90° counterclockwise about A(2,2) gives image points B' and C' (see attached diagram)
