Answer:
25
Step-by-step explanation:
Inverse variation means ...
y = k/x
For the given values, we can find k to be ...
k = xy = (5)(10) = 50
Then for x=2, we have ...
y = 50/x
y = 50/2
y = 25 . . . when x=2
Answer:
200 minutes
Step-by-step explanation:
In order to find the range, you have to subtract the greatest number to the lowest number. In this case, 400 is the smallest number, and 600 is the greatest number. 600-400 is 200 minutes.
Answer:
f(x)=3x^2+2x-10 if x=2
f(x)=3(2)^2+2(2)-10
f(x)=3(4)+2(2)-10
f(x)=12+4-10
f(x)=16-10
f(x)=6
g(x)=3x-3 if g(x)=2
g(x)=3(2)-3
g(x)=6-3 =3

Answer:
500 plants
Step-by-step explanation:
Total capacity of barrel = 150 L
1 liter = 1000 mL
Total capacity of barrel in mL = 150*1000 mL = 150,000 mL
amount of water given to each plant by Mattie = 300 mL
Let there be x plants
Then, total amount of water given to x plant by Mattie = 300*x mL
We know that full rain barrel has 150,000 mL
so total amount of water given to x plant by Mattie should be equal to full rain barrel capacity.
Substituting value of full rain barrel capacity and total amount of water given to x plant
Mathematically it can be written as
total amount of water given to x plant by Mattie = full rain barrel capacity
300*x mL = 150,000 mL
=> x = 150,000/300 = 500
Thus, 500 plants can she water with a full rain barrel.
Answer:
d. -4
Step-by-step explanation:
Let's plug in g
8 - |2(-3.5) - 5|
8 - |-7-5|
8 - |-12|
The absolute value is always positive of any number,
8 - 12
= -4
