Plug in a -20 wherever you see a b
(-20)^2 +4*-20-89/13
400 + -80-89/13
400 - 169/13
400-13
=387

Answer:
You would expect to get 50 heads
Step-by-step explanation:
Each time you flip a coin you will either get heads or tails. This means that you have a 1/2 probability of getting heads. If you use this then you need to multiply 1/2 and 100 to get the expected amount of heads. Multiplying by a half is just dividing by 2. Therefore, the answer is 100/2 = 50. The answer is 50 heads
Answer:
Step-by-step explanation:
6x - y = 1
6x - 1 = y.....rearrange
y = 6x - 1......slope is 6. A parallel line will have the same slope.
y = mx + b
slope(m) = 6
(-5,-5)...x = -5 and y = -5
now we sub and find b, the y int
-5 = 6(-5) + b
-5 = -30 + b
-5 + 30 = b
25 = b
so ur equation is : y = 6x + 25 <==
