Answer:
Step-by-step explanation:
5x −11+11<-11+11
5x<0
5x/5<0/5
x<0
4x+2 -2 >14 -2
4x>12
4x/4>12/4
x>3
there both open not closed
hope this helps
Answer:
x=-10
Step-by-step explanation:
15-2(x+5)=25
multiply the 2 by the x and 5 and you get
15-2x-10=25
since the 15 and the negative 10 are on the same side you add them together and get
5 -2x= 25
-5 -5
-2x =20
Then divide the -2/20= -10
Step-by-step explanation:
second terms:
ar=3/2
forth term
ar^3=3/8
combine two equation:
r^2=1/4
r= +1/2 or -1/2
a=3 or -3
The solution to the equations is x=20 and y=40
Step-by-step explanation:
Let,
Small tier = x
Medium tier = y
According to given statement;
1.The situation with a system of equations.
3x+y = 100 Eqn 1
3x+2y=140 Eqn 2
2. Solving the System of equations;
The solution to the equations is x=20 and y=40

Answer:
(-2, 0.25)
(-1, 0.5)
(0, 1)
(1, 2)
(2, 4)
Those are the points. I just plugged each x value into the equation to get the y value. Hope it helps!
