Step-by-step explanation: the answer is x = 1/2
Step-by-step explanation:
You would start by using one of the equations to find y with x in the equation. You want to pick the easier one. I picked this one because it was evenly divisible.
5x+5y=50
5x=-5y+50
x=-y+10
Then you what to plug that in to the second equation and solve for y.
3(-y+10)+4y=32
-3y+30+4y=32
-3y+4y=2
y=2 (because you combined like terms)
Then you would plug back into the first equation and solve for x.
5x+5(2)=50
5x+10=50
5x=40
x=8
x=8, y=2
Answer:
c=31.42
Step-by-step explanation:
It would be greatly appreciated if you gave me brainlest.
30-5*4+2
30-20+2
10+2
12 is the answer
Answer:
Closed and Bounded.
Step-by-step explanation:
Hi there!
1) Let's start by finding the values in which the function is defined. Remember that this can be rewritten:
Since every quadratic root are defined for values 
0 then, this help us to understand that we need calculate what interval this Domain is:
![D=[-2,2]](https://tex.z-dn.net/?f=D%3D%5B-2%2C2%5D)
2) Graphically speaking, the domain is closed. For the values -2 and 2 are included, and bounded.
Bounded functions have all of their points contained by some circle origin centered. Check it out below.
