Divide 20 by 4=5
then 5 by 7=5/7
k=5/7
Answer:
8:10
Step-by-step explanation:
8 parts for brown sugar and 10 parts flour.
In simplest, 4:5 (divide 8 and 10 by 2)
√10 · √6 = √(10 · 6) =
= √60 = √(4 · 15) = √(2² · 15) = 2√15
<span>perpendicular slope :
m1 * m2 = -1
1/2 * m2 = -1
m2 = -2
y = -2x + b
2 = -4 +b
b = 6
y = -2x + 6
