Answer:
C
Step-by-step explanation:
You just find the rate of change. So you would divide 30/1 which equals 30. So the equation is y=30x.
Answer:
Mother: 40 years old
Rakhi: 15 years old
Step-by-step explanation:
Solution :
Let present age of Rakhi = x years
Present age of Mother = 4x
5 years later
Age of Rakhi =x+5
Ag of Mother =4x+5
Given 4x+5=3(x+5)
4x−3x=15−5
⇒x=10
Mother's age =4x=40 years
Plug 10 in for x to find Rakhis age
Answer:
No, I don't think so.
Step-by-step explanation:
If his suitcase weighs 23 kg and 10 kg is 22 pounds. You could seperate it. 10, 10, and 3 meaning 22+22= 44. This would mean that 1 kg would equal about 2.2 a pound. So 44 + ( 2.2 x 3 ) = 50.6 kg.
It would be 0.6 k.g over. I think this is right unless I calculated this wrong.

Step-by-step explanation:
To find the inverse of a function, just “trade” x and y and solve for the “new” y. The graph of the inverse is the reflection of the original function over the line y=x.
Rewrite the function

as the equation, y=x+3
Trade x and y.
X=y+3
The symbol for the inverse if 

Answer: 21.3 km
Step-by-step explanation:
Given: On each of 3 days the distance traveled by Derrick to school = 6.45 km
The distance rode by Derrick to library = 150 meters
Since, 1 m=
Thus, the distance rode by Derrick to library = 
The distance rode by Derrick to home = 500 meters.
Thus, the distance rode by Derrick to home = 
Distance he rode in each day = 
Now, Distance he rode in 3 days =
