Answer:
Step-by-step explanation:
So the slope of the line is y = -9x + b
We have
y = -9x + b
Add 9x to both sides
y + 9x = -9x + 9x + b
y + 9x = b
switching sides,
b = y + 9x
Plug in the (x, y) values for point (4, 0)
b = 0 + 9(4)
b = 36
So the equation of the line is
Answer:
Step-by-step explanation:
In multiplication of fractions you can do this:
.
So that is exactly what we are going to do here:
We know that 12 divided by -6=12/-6 =-2.
We also know assuming x isn't 0 that x^a/x^a=1.
On the last fraction, the only thing you can do there to simplify is use the following law of exponents: .
So we have
Simplifying a bit and leaving out the ( ).
Answer:
Step-by-step explanation:
If you graph the equation, you'll see that the y-intercept is -3 and the slope is
Answer:
P(B | A) = 0.80
Step-by-step explanation:
For independent events A and B, P(B | A) = P(B)
Therefore, P(B | A) = 0.80
