S=2d
4s+3d=300000-80000
4s+3d=220000, now using s=2d in this equation you get:
4(2d)+3d=220000
8d+3d=220000
11d=220000
d=20000
So each daughter gets 20000 and each son gets 40000.
Answer:
The first picture without the diagram is true, and the other one is false.
Step-by-step explanation:
A relation can be a function if the domain has exactly one range. IT CANT HAVE TWO Y-VALUES.
Answer:
The resistance approaches infinity
Step-by-step explanation:
We are given
The resistance, R, to electricity of a cylindrical-shaped wire is given by the equation
where
p represents the resistivity of the wire’s material
L represents the length of the wire
d represents the diameter of the wire
now,
d approaches to 0
so, we can plug d=0 and find R
So,
The resistance approaches infinity
Solve the following system using elimination:
{x - 2 y = -23 | (equation 1)
{x - y = 7 | (equation 2)
Subtract equation 1 from equation 2:
{x - 2 y = -23 | (equation 1)
{0 x+y = 30 | (equation 2)
Add 2 × (equation 2) to equation 1:
{x+0 y = 37 | (equation 1)
{0 x+y = 30 | (equation 2)
Collect results:
Answer: {x = 37 , y = 30
