I would say the best estimate would be 9 because the real answer is 8.71 and if you round that to the 1 place the answer would be 9.
Answer:
C. b²< 40
Step-by-step explanation:
2x²+ bx + 5=0 has no real solutions
=> D< 0
b² < 4ac
b²< 4(2)(5)
b²< 40

So first, you need to identify the parts of this equation.
3x is the slope of the line, which is
.
-5 is the y-intercept. or the part of the line that touches the y-axis.
The first thing you want to do is plot the y-intercept. SO, go to the y-axis and find -5. Plot your point there.
Now, use the slope
to find your next plot. Since slope is
, you go up three, and over to the right one.
Now, draw a line connecting the dots. Your slope should be positive and look like > /
