Answer:
a) -20/11 b) -10/7
Step-by-step explanation:
a) m=(y2-y1)/(x2-x1)
m=(-4-16)/(4-(-7))
m=-20/(4+7)
m=-20/11
b) m=(y2-y1)/(x2-x1)
m=(-10-(-20))/(-12-(-5))
m=(-10+20)/(-12+5)
m=10/-7
m=-10/7
because they allow us to make direct comparisons
but tan 45° is 1;
B
k=0
Problem: 8-0.3k=8
1) Subtract 8 from both sides:
-0.3k=0
2) Divide both sides by -0.3
