Question

Solve the following system of equations. 2x-3y+z=2 13x-7z=-5 3x+y=2

Answer #1

2x - 3y + z = 2

13x - 7z = -5

3x + y = 2

**x = 17/30 , y = 3/10 , z = 53/30**

Solve the following system of equations.
{−x+4y−z=-4
3x−y+2z=6
2x−3y+3z=−2
Give your answer as an ordered triple
(x,y,z).

solve the system of equations
1: y=3x^2-2x-1
2x+3y=2
2: x^2+(y-2)^2=4
x^2-2y=0

1.Solve the system of equations. 2x + 3y = 6 and x – y = ½
2.Is x = y2 a function?
3.Which do we use to determine if a graph represents a
function?
4.Find the average rate of change from 2 to 5 for the function,
f(x) = -4x + 1.
5.What are the slope and y-intercept for the function, h(x) =
-3x + 4?

4. Solve the system of equations.
2x – y + z = –7
x – 3y + 4z = –19
–x + 4y – 3z = 18.
A. There is one solution (–1, –2, –3).
B. There is one solution (1, 2, 3).
C. There is one solution (–1, 2, –3).
D. There is one solution (1, –2, 3).

1-solve for x and y
3x+(y-2)i=(5-2x)+(3y-8)i
2-solve for z and write the answer with standard form
(3-2i)z+(4i+6)=8i
3-preform the indicated operation and write the answer with
standard form
(9+5i)-(6+2i)

1. solve the system of equations:
x+3y=9
3x+9y=27
please solve to get the x and y solution
2. solve the system of equations, please state the x and y
solution
9x-4y=23
15x+4y=41
3. solve the system of equations please state the x and y
solution
x - y - z = 1
5x + 6y + z = 1
30x + 25y = 0

For a real number "a", consider the system of equations:
x+y+z=2
2x+3y+3z=4
2x+3y+(a^2-1)z=a+2
Which of the following statements is true?
A. If a= 3 then the system is inconsistent.
B. If a= 1 then the system has infinitely many solutions.
C. If a=−1 then the system has at least two distinct
solutions.
D. If a= 2 then the system has a unique solution.
E. If a=−2 then the system is inconsistent.

1) Solve these equations: 3x-y=-11
x+2y=8
2) Solve these equations:
x+y+z=6
x-y-z=-4
2x+y-4z=-8

Solve the system of equations given below. 2x+5y+z= -1, 3x-5y-z=
6, 5x+y+3z= 10.

for 10-12 you will solve the following system of equations:
2x+y+z=-2 2x-y+3z=6 3x-5y+4z=7 10) what is the solution for x? a)2
b)-3 c)infinitely many solutions d)no solution 11) what is the
solution for y? a)2 b)0 c)inifinitely many solution d)no solution
12) what is the solution for z? a)4 b)-8 c)infinitely many
solutions d)no solutions
