Answer there is no choice, but it is x+1/3+2 1/2.
Step-by-step explanation:
Answer:
what is half of 30 percent?
Step-by-step explanation:
and that might give you the half of 30 percent and all you will have to do is figure out how 30 percent is all toghter and then add the anthor numbers and also but lastly put in on a experession in simplifed form.
C = -840
Isolate C by subtracting 900 on both sides:
C = 60-900
Which then gives u C = -840
A) (-6,-3], (-3, 3), [3,7)
B) (-5,-5), (-3,-3), (-1,6)
C)6
D) X=5
E) f(2)= -3
F)4 & 6
Answer:
A. {x,y}={-2,-3}
// Solve equation [2] for the variable x
[2] x = 2y + 4
// Plug this in for variable x in equation [1]
[1] (2y+4) - y = 1
[1] y = -3
// Solve equation [1] for the variable y
[1] y = - 3
// By now we know this much :
x = 2y+4
y = -3
// Use the y value to solve for x
x = 2(-3)+4 = -2
B. [1] 3x=3y-6
[2] y=x+2
Equations Simplified or Rearranged :
[1] 3x - 3y = -6
[2] -x + y = 2
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = x + 2
// Plug this in for variable y in equation [1]
[1] 3x - 3•(x +2) = -6
[1] 0 = 0 => Infinitely many solutions

System of Linear Equations entered :
[1] 4x - y = 2
[2] 8x - 2y = 4
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 4x - 2
// Plug this in for variable y in equation [2]
[2] 8x - 2•(4x-2) = 4
[2] 0 = 0 => Infinitely many solutions
