Answer:
The test was worth 40 points
Step-by-step explanation:
34/40 = .85
85%
For perpendicular lines, m2 = -1/m1 = -1/(-2/3) = 3/2 [m1 = -2/3]
Required equation is y + 2 = 3/2(x + 2) => y + 2 = 3/2 x + 3 => y = 3/2 x + 1
Equation x y = -4y implies x=-4
Replacing the value of x in the following equation:
-4y = 2(-4)-1 implies y = 9/4 = 2.25
Answer:
A
Step-by-step explanation:
It is the only one that has both heads and tails equally on all options, instead of heads heads or tails tails. There aren't any fair coins that are like that
