Step-by-step explanation:
Answer:
y = -6/5x + 13 4/5
Step-by-step explanation:
Step 1: Perpendicular slope
We need to find the perpendicular slope, or the opposite reciprocal.
This means we change the sign (positive, negative)and flip the numbers
Perpendicular sope to 5/6x = -5/6x = -6/5x
Step 2: Plug in coordinates
Now we plug in the coordinates for y = -6/5x + b
3 = -6/5(9) + b
3 = -10.8 + b
b = 13.8 or 13 4/5

Answer: w=5
Step-by-step explanation:
58=l+l+w+w
l=4w+4
58=(4w+4)+(4x+4)+w+w
58=8w+8+w+w
58=10w+8
50=10w
5=w
w=5
l=4w+4
l=4(5)+4
l=20+4
l=24
check:
w=5, l=24,
5*24=120
our answer is correct
