Answer:
T=-80
Step-by-step explanation:
P=kr/T when p=4 T=20 r= 2 k=40 so when p=-5,r=10 then T=-80
Answer:
The answer is B
Step-by-step explanation:
1)
These are in Y = MX + B form
The first line has a positive slope, so the coefficient "M" is positive.
The second line has a negative slope, so the coefficient "M" is negative.
2)
The first line has a filled in dot at Y = 2.
Since it's to the left (less than X direction)...
X <= 0
The second has an empty circle at Y = 4.
Since the line goes to the right....
0 < X
3)
Also, the "+2" and the "+4" in the equation as the "+ B" indicates where each line will cross the Y axis.
From these things, we can infer that B is the correct answer.
Answer:
2
Step-by-step explanation:
2u+10=22+u
or,2u-u=22-10
or, u=2____1
Answer:
0.5 of the number 8 would be 0.04.
3 - 2x + 5 < -4(x + 2)
-2x + 8 < -4(x + 2)
-2x + 8 < -4x - 8
-2x + 8 + 4x < -8
2x + 8 < -8
2x < -8 - 8
2x < -16
x < -16/2
x < -8
Answer: A) x < -8
