Answer:
v = Δs/Δt
Step-by-step explanation:
This: Δs is the change in speed or can also be the rate
This: Δt is the change in time
4 is the x value and -3/4 is the y value. (x,y)
To plot this point, move over to the right to 4, then go down 3/4. So the point will be in the bottom right quadrant.
Answer:
The best estimate of the area of the larger figure is 
Step-by-step explanation:
step 1
<em>Find the scale factor</em>
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor
Let
z----> the scale factor
x-----> the corresponding side of the larger figure
y-----> the corresponding side of the smaller figure
so

we have


substitute
-----> the scale factor
step 2
<em>Find the area of the larger figure</em>
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z----> the scale factor
x-----> the area of the larger figure
y-----> the area of the smaller figure
so

we have


substitute and solve for x

27:6, 36:8, 45:10 are the ratios to the right handed students to the left handed students
Given inequality:
-5z+2>5
Solving for z.
Subtract 2 from both sides
-5z>3
Multiply both sides by -1 and reverse the inequality.
(-1 x -5z) < (-1 x 3)
5z<-3
Divide both sides by 5.
z<-3/5
Answer: z < -3/5
