The formula of a slope:
We have the points A(-6, 6) and B(12, 3). Substitute:
Therefore we have .
Put the coordinates of the point B to the equation:
<em>add 2 to both sides</em>
Answer:
Answer:
15
Step-by-step explanation:
The equation is just a plug in and solve. you have your given variables and all you have to do it plug them into the matching spot and solve
R=8 P=7
8+7=15
Let x be a random variable representing the length of a text messaging conversation, then
P(x > 3) = 1 - P(x < 3) = 1 - P(z < (3 - 2)/0.5) = 1 - P(z < 2) = 1 - 0.97725 = 0.02275
The given quadratic describes a parabola that opens upward. Its one absolute extreme is a minimum that is found at x = -3/2. The value of the function there is
(-3/2 +3)(-3/2) -1 = -13/4
The one relative extreme is a minimum at
(-1.5, -3.25).
_____
For the parabola described by ax² +bx +c, the vertex (extreme) is found where
x = -b/(2a)
Here, that is x=-3/(2·1) = -3/2.
