Answer:
The answer to your question is 1.- (-3, 4) 2.- (3, 1) None of the choices
Step-by-step explanation:
1.- The solution of a system of equation by the graph method is the point in which the lines cross. In this graph we observe that this point is approximately
(-3, 4).
2.-
Equation 1 x + y = 4
Equation 2 x - y = 2
Solve by the combination method
x + y = 4
x - y = 2
2x 0 = 6
2x = 6
Solve for x
x = 6/2
x = 3
Substitute x in equation 1 to find y
3 + y = 4
Solve for y
y = 4 - 3
y = 1
Solution (3, 1)
-4 < n < 6 . . . . . represents all numbers n between -4 and 6 (not inclusive).
Y=-5x+14............... mark as brainpower if right lol
Step-by-step explanation:
2/x + 3 = 1/x
2/x - 1/x = -3
1/x = -3
1 = -3x
x = 1/(-3) = -1/3
All i got is (3,8) (2,5) and (2,-6)
