The equation
has it's solutions given by
. This is the quadratic formula.
Looking at your equation we see a=1; b=-3 and c=-6 so by the quadratic formula,
I'm sure you can work out what 9+24 is and so find the correct option :)
Simple...
when they ask for the rate of change they ask for
slope -->>
Using
to find the rate of change for (-3,0) and (-2,-5)
m=-5
Thus, your answer.
Answer:
see explanation
Step-by-step explanation:
In a rectangle
• All angles are right angles
• the diagonals are congruent
In Δ WXV the sum of the 3 angles = 180°
∠ WXZ = ∠ XWY = 
= 
= 58°
∠ YXZ = 90° - 58° = 32°
∠ WVZ = 180° - 64° = 116° ( adjacent angles are supplementary )
∠ XWZ = 90° ( by definition of rectangle )
∠ XZY = ∠ WXZ = 58° ( corresponding angles )
You have the right idea but the endpoint is at the wrong location. Instead, the green dot should go at -1. The shading is to the right. We use a closed filled in circle here (instead of an open hole) to tell the reader "include the endpoint". So -1 is part of the solution set.
In short, the graph consists of a closed filled in circle at -1 with shading to the right. This visually describes all values that are larger than -1, or equal to -1.
B is the correct answer
good luck
