Answer:

59; 44 & 68; 22.5; 44

Step-by-step explanation:

10.

x + 57 = 116
x = 116 - 57
x = 59

11.

y = 180 - 112 = 68
x= 180 - 2*68 = 44

12.

4x + 10 = 180 - 2*40
4x + 10 = 100
4x = 90
x = 90/4
x = 22.5

13.

SG = HT/2
SG = 88/2 = 44

Answer:

See below ~

Step-by-step explanation:

Q1

y = (x + 3i)(x - 7)
y = x² + 3ix - 7x - 21
y = x² + (3i - 7)x - 21

Q2

y = (x - √5)(x - i)
y = x² - √5x - ix + √5i
y = x² - (√5 + i)x + √5i

What are the coordinates of the triangle after a dilation with a scale factor of 1/2? Center it at (-3, 0) .

algol13

On the graph, the distance from each point to the center of dilation is cut in half.

The vertices become ...
(-5,4) ⇒ (-4, 2)
(3, 8) ⇒ (0, 4)
