Step-by-step explanation:
option C and E are the two equations
Option C, equation is 3x+2y= -14
LHS= 3(-6)+2(2) = -18+4 = - 14 =RHS
Again, option E equation x+y= -4
LHS= -6+2 =-4 =RHS
Answer:
The correct answer is B
Step-by-step explanation:
I know this is the answer because I took the test and got it right.
Answer:
f(x) is even
Step-by-step explanation:
f(x) = 3
f(-x) = 3
f(x) = f(-x)
2y² + y - 3
(2y+3)(y-1)
2y(y-1) + 3(y-1)
2y² - 2y + 3y - 3
2y² + y - 3
2y + 3 = 0
2y = -3
y = -3/2
y = -1 1/2
y - 1 = 0
y = 1
2y² + y - 3 = 0
2(-3/2)² + (-3/2) - 3 = 0
2(9/4) - 3/2 - 3 = 0
18/4 - 3/2 - 3 = 0
18/4 - (3/2 * 2/2) - 3(4/4) = 0
18/4 - 6/4 - 12/4 = 0
(18 - 6 - 12)/4 = 0
(18 -18)/4 = 0
0/4 = 0
0 = 0
