Answer:
1. 4 1/8 +2/8
33/8+2/8
=35/8 0r 4 3/8
2.8 4/16 +12/16
132/16+12/16
=144/16
=9
3. 2 65/100+91/100
265/100+91/100
=356/100
=89/25
4. 4 14/40+36/40
174/40+36/40
=210/40
=21/4
5.1 12/20+10/20
32/20+10/20
=42/20
=21/10
Step-by-step explanation:
Answer:
b; 1 real root and 2 imaginary roots
Step-by-step explanation:
From here, we have
x(x^2 + 121) = 0
x = 0 (1 real root)
or
x^2 + 121 = 0
x^2 = -121
x = √(-121) (2 imaginary roots)
so is would be two complex numbers from above
Answer:
A. (-4,0)
Step-by-step explanation:
Answer:
we make the denominator equal to zero then we get the domian
Answer:
y=-3x-3
Step-by-step explanation:
To get a perpendicular line you take the negative reciprocal of the slope, so in this case it would equal -3. Now use point-slope form to get your equation. Point slope form says that y-y1=m(x-x1) where m is your slope and x1 and y1 are the points that the graph passes through. So in this case x1=-3, y1=6, and m=-3. This gives you the equation y-6=-3(x+3). Distribute to y-6=-3x-9, and finally add 6 to both sides to get y=-3x-3
