Answer:
x=30 x=-20
Step-by-step explanation:
We can use the zero product property to set the factors equal to zero
x-30 = 0 and x+20 =0
x=30 x=-20
On each filip the probability of landing heads-up is 1/2. The probability of getting 6 heads in 6 flips is:
![(\frac{1}{2})^{6}=\frac{1}{64}](https://tex.z-dn.net/?f=%28%5Cfrac%7B1%7D%7B2%7D%29%5E%7B6%7D%3D%5Cfrac%7B1%7D%7B64%7D)
The answer is: 1/64 or 0.015625
Answer:
y = (9/5)x - 9.6 in slope intercept (not sure if this counts as reduced?) and y + 6 = 9/5 ( x - 2 ) point slope
Step-by-step explanation:
We need to find the point slope formula. This is y-y1 = m(x-x1). First, we need to find the slope, and we can start to begin to make our equation from there. Slope = rise/run, so 9/5 should be our slope.
y - y1 = 9/5(x - x1) is our new eqn.
Then, we can put one of the points from our line into our eqn, since both pass through our eqn, we can use either point for our calculations.
Sticking with just the first point and substitutuing in values, we get:
y + 6 = 9/5 ( x - 2 ) and now we have to simplify.
y = 9x/5 - 18/5 - 6
y = 9x/5 - (15/5 + 3/5) - 6
y = 9x/5 -3.6-6
y = 9x/5 -9.6
