Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y ), thus
A(1, 4 ) → A'(1, - 4 )
B(3, - 2 ) → B'(3, 2 )
C(4, 2 ) → C'(4, - 2 )
Answer:

Step-by-step explanation:
The absolute value is always positive. It can never be negative. It is considered to be the distance from 0 of a certain number.

Area by Heron's formula:
semiperimeter = (15 + 20 + 25)/2 = 60/2 = 30 cm

The formula of the area of a triangle: Area = 1/2 * base * height
1/2 * 25 * height = 150
12.5 * height = 150
height = 150/12.5
height = 12 cm
Answer:

Step-by-step explanation:
step 1: add -5y to both sides
4x = -5y + 17
step 2: divide both sides by 4
4x/4 = -5y + 17/4
x = -5/4y + 17/4
