0=4(x²+8x+16)-12
0=4x²+32x+64-12
0=4x²+32x+52
0=x²+8x+13
D=b²-4ac
D=64-52=12
x=(-b-√D)/2a
x=(-b+√D)/2a
x=(-8-2√3)/2= (-2(4+√3))/2= -(4+√3)
AND
x=(-8+2√3)/2=-2(4-√3)/2= -(4-√3)
The answer is true since the amount of interest each year is inequality
Answer:
1. -20 is the y intercept
2. 2x+4y=16
2x/2+4y/2=16/2
x+2y=8
x-x+2y=8-x
2y=-x+8
2y/2=-x/2+8/2
y=-x/2+4
4 is the y intercept
3. 2y+3x=7
2y+3x-3x=7-3x
2y=-3x+7
2y/2=-3x/2+7/2
y=-3
x/2+3.5
3.5 is the Y intercept
4. -3 is the y intercept
Answer:
The answer is 0 or 1
Step-by-step explanation:
nobody give you a very long question to solve so I think it has a short solution. When you multiply all equation with together.. after a step it must equal to 0 or 1
Answer:
a) the scatter plot show a correlation
