Step-by-step explanation:
MULTIPLIED BY THE NUMBER TO THE LEFT LOL
The slope of a perpendicular line is the opposite reciprocal of the original slope. So the slope is 1/3.
Answer: y = x/3 - 2
Work in attached picture.
Answer:
1. x/2=1.75/3.5 x=1
2. 4/2=y/3.5 y=3.5
3. P (Figure Left)=3+5+2+1+4+8+3+2=28 cm
A (Figure Left)=8x2-2x1-3x2=8 cm2
4. P (Figure Left) / P (Figure Right) = 1/1.75 = 28/ P (Figure Right)
P (Figure Right)= 49 cm
A (Figure Left) / A (Figure Right) = 1/1.752 = 8/ A (Figure Right)
A(Figure Right)= 24.5 cm2
Step-by-step explanation:
1. x/2=1.75/3.5 x=1
2. 4/2=y/3.5 y=3.5
3. P (Figure Left)=3+5+2+1+4+8+3+2=28 cm
A (Figure Left)=8x2-2x1-3x2=8 cm2
4. P (Figure Left) / P (Figure Right) = 1/1.75 = 28/ P (Figure Right)
P (Figure Right)= 49 cm
A (Figure Left) / A (Figure Right) = 1/1.752 = 8/ A (Figure Right)
A(Figure Right)= 24.5 cm2
