Answer:
WHAT
Step-by-step explanation:
Answer:
y= 126
Step-by-step explanation:
The given equation is: y= 3x-2x^2+5x^3
Substituting the value x=3 in the above equation,we get
y= 3(3)-2(3)^2+5(3)^3
⇒y= 9-2(9)+5(27)
⇒y= 9-18+135
⇒y= 126
Answer: n = -198
Step-by-step explanation: To find n we need to work backwards, so we need to multiply -11 x 18 to get -198. So n would be -198.
Answer:
System of Linear Equations entered :
[1] 6x-2y=8
[2] 3x-4=y
Equations Simplified or Rearranged :
[1] 6x - 2y = 8
[2] 3x - y = 4
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = 3x - 4
// Plug this in for variable y in equation [1]
[1] 6x - 2•(3x-4) = 8
[1] 0 = 0 => Infinitely many solutions
