Answer:
y=1; x=2
Step-by-step explanation:
Substitution:
x=2y
2x+5y=9
=> if x=2y, plug in the x value into other equation, so
----------------------------------------------------------------------------
2(2y)+5y=9
4y+5y=9
9y=9
y=1
You have the Y value, so now solve for X
-----------------------------------------------------------------------
plug in y value to x=2y
so x=2(1)
x=2

Answer:
B. 192.5 ft³
Step-by-step explanation:
To find the volume of a triangle prism, multiply the base, height, and length together, and then divide it by 2 (or multiply that by 0.5).
(5 * 7 * 11)/2
Multiply 5 by 7 to get 35.
(35 * 11)/2
Multiply 35 by 11 to get 385.
385/2
192.5 ft³ is the volume of this triangluar prism.
Answer:
P(0) = 7,917
Step-by-step explanation:
The population of the community is given by the following formula:
In which P(0) is the initial population and r is the growth rate.
The initial population P0 has doubled in 5 years.
This means that
Which lets us find r.
Applying the 5th root to both sides
So
Suppose it is known that the population is 12,000 after 3 years.
With this, we find P(0)
ANSWER
b>1
EXPLANATION
The given inequality is;
2 (b - 4) > -6
Expand the parenthesis to get,
2b-8>-6
2b>-6+8
Simplify the right hand side.
2b>2
Divide both sides by:
b>1
