This system has one solution. Here are my steps to solving this problem:
y=x+1
2(x+1) - x = 2
2x +2 - x = 2
2x - x + 2 = 2
x + 2 = 2
- 2 - 2
----------------
x = 0
y = 0 + 1
y = 1
I hope this helps you!
Y=45x + 25; x is the classes Angie takes and 25 is the y-intercept(the enrollment fee).
Answer:
You can substitute the x value of coordinate (x,y) in the equation. If the outcome = the y value in the coordinate (x,y), then you have determined it to be on the system of linear equations.
Step-by-step explanation:
Point P has a coordinates: ( Px , Py ).
You can choose which value is easy to substitute. Eighter start with the Py or you could start with the Px. It could save you time if you pick the right one for the job.
If you want to verify if any point is valid in any (linear) equation(s), you can:
a) substitute the x value of coordinate (x,y) in the equation, and if the outcome has the same value as y in the coordinate (x,y), then that point is a valid solution of the (linear) equation.
b) substitute the y value of coordinate (x,y) in the equation, and if the outcome has the same value as x in the coordinate (x,y), then that point is a valid solution of the (linear) equation.
450 divides by 10 to receive a product of 45
Answer:
Minimum surface area =
Step-by-step explanation:
We are given that
Width of container=x cm
Length of container=2x cm
Volume of container=
We have to find the minimum surface areas that this container will have.
Volume of container=
Surface area of container=
Because the container does not have lid
Surface area of container=
Differentiate w.r.t x
Substitute 
Again differentiate w.r.t x
Substitute x=3.4
Hence, function is minimum at x=3.4
Substitute x=3.4
Then, we get
Minimum surface area =
