Answer:
y= --3/2x + 4
Step-by-step explanation:
If you would like to know the discriminant of the quadratic equation 0 = -x^2 + 4x - 2, you can do this using the following steps:
<span>0 = -x^2 + 4x - 2
</span>
<span>0 = ax^2 + bx + c
a = -1, b = 4, c = -2
D =
b^2 - 4 * a * c = 4^2 - 4 * (-1) * (-2) = 16 - 4 * 2 = 16 - 8 = 8
</span>
The correct result would be b. 8.
Answer:
Step-by-step explanation:
Slope intercept form: when is the slope of the line and is the y-intercept (the y-coordinate of the point the line crosses the y-axis)
<u>1) Find the slope (</u><u>)</u>
when the points are and
We can use any two points that the table gives us to plug into this equation. For example, we can use the points (14,0) and (0,7):
Simplify the fraction
So far, our equation looks like this:
<u>2) Find the y-intercept (</u><u>)</u>
The y-intercept is the y-coordinate of the point the line crosses the y-axis, or in other words, it's the value of y when x is equal to 0.
Looking at the table, we can see that y is equal to 7 when x is equal to 0, so, therefore, .
Now, this is our final equation after plugging in and :
I hope this helps!
Answer:
6.4 - x
Step-by-step explanation:
Positive difference is the bigger number- the smaller number
Negative difference is the smaller number- the bigger number
In this case, we do not know which is bigger so it is advisable to go for the known number- the unknown number. that is 6.4 - x
