Answer:

G = (-1.5,1.5)

Step-by-step explanation:

Given

M = (-7,5)

A = (6,5)

T = (4,-2)

H = (-9,-2)

Required

Determine the coordinate of G

From the complete question, G is at the intersection of MT and AH.

So, G is calculated using midpoint formula

G = \frac{1}{2}(x_1 + x_2, y_1 + y_2)

For MT:

M = (-7,5)      T = (4,-2)

G = \frac{1}{2}(-7 + 4, 5 -2)

G = \frac{1}{2}(-3, 3)

Open bracket

G = (-1.5,1.5)

To show that G = (-1.5,1.5)

We have:

A = (6,5)       H = (-9,-2)

G = \frac{1}{2}(x_1 + x_2, y_1 + y_2)

G =\frac{1}{2}(6-9,5-2)

G = \frac{1}{2}(-3, 3)

Open bracket

G = (-1.5,1.5)

Hence, the coordinates of G is:

G = (-1.5,1.5)

Answer:

part 1= "72=(2w)+(w-15)"

part 2= "29"

I'm not sure if they want "w = abc"

I used that equation to solve part 2

PLEASE HELP WITH 1-3 ILL MARK U THE BRAINLIEST
sammy [17]

Answer:

1:A(-6,-1) B(-14,0) C(-11,4)

2:D(6,-3) E(2,-3) F(3, -4.5) G(5, -4.5)

3:H(-4,1) I(-4, 6) J(0,6) K(0,1)

Step-by-step explanation:

Before we begin, lets define the transformations:

(x, y)

T(a, b) = (x+a, y +b)

Rxaxis = (x, -y)

Ryaxis = (-x, y)

r(180, 0) = (-x, -y)

D.5(1/2x, 1/2y)

R(-90, O) = (-y, x)

1. T. A(6,-1) B(14,0) C(11,4)

   Rx. A(6, 1) B(14,0) C(11,-4)

   r180 A(-6,-1) B(-14,0) C(-11,4)

2. Rx D(-12,-6) E(-4,-6) F(-6, -9) G(-10, -9)

   Ry D(12,-6) E(4,-6) F(6, -9) G(10, -9)

   D.5 D(6,-3) E(2,-3) F(3, -4.5) G(5, -4.5)

3. Rx=1 H(-1,2) I(4, 2) J(4,-2) K(-1,-2)

   T H(1,4) I(6, 4) J(6,0) K(1,0)

   r-90 H(-4,1) I(-4, 6) J(0,6) K(0,1)

Solve for x and state the measure of the angles with an x in them
Arada [10]

Answer:

x = 83

Step-by-step explanation:

The sum of the angles of a quadrilateral is 360

75+x+97+105 = 360

Combine like terms

x+277=360

Subtract 277 from each side

x+277-277=360-277

x = 83
