Remove the absolute value term. This creates a ±
3x = +9

3x + 9 (Divide by 3)

X=9

3x =-9 (Divide by 3)

X= -3

So; X=3,-3
The solution to the equation includes both the positive and negative portions of the solution.

Derive the equation of the parabola with a focus at (0, −4) and a directrix of y = 4.
Goshia [24]
\sqrt{(x_{0} - 0)^{2} + (y_{0} - (-4))^{2}} = |y_{0} - 4|
<span>\sqrt{(x_{0} - 0)^{2} + (y_{0} + 4)^{2}} = |y_{0} - 4|
</span>(x_{0} - 0)^{2} + (y_{0} + 4)^{2} = (y_{0} - 4)^{2}
(x_{0})^{2} + (y_{0} + 4)^{2} = (y_{0} - 4)^{2}
x_{0}^{2} + (y_{0}^{2} + 4y_{0} + 4y_{0} + 16) = y_{0}^{2} - 4y_{0} - 4y_{0} + 16
x_{0}^{2} + (y_{0}^{2} + 8y_{0} + 16) = y_{0}^{2} - 8y_{0} + 16
x_{0}^{2} + y_{0}^{2} + 8y_{0} + 16 = y_{0}^{2} - 8y_{0} + 16
x_{0}^{2} + 16y_{0} = 0
16y_{0} = -x_{0}^{2}
\frac{16y_{0}}{16} = \frac{-x_{0}^{2}}{16}
y_{0} = -\frac{1}{16}x_{0}^{2}
y = -\frac{1}{16}x^{2}

The answer is C.

mrs_skeptik [129]

Answer:

x=9

Step-by-step explanation:

17x - 12 = 114 + 3x

First  Subtract 3x from both sides

14x - 12 = 114

Add 12 to both sides

14x=126

Divide by GCF (14)

x=9

A line has a slope of a and has a y-intercept of (0,b). Which equation represents this line?
Papessa [141]

Step-by-step explanation:

General line equation: y = mx + c, where m is the slope of the line and c is the y-intercept.

We have y = ax + b.

=> y - b = ax

=> y - b = a(x - 0).

The answer is option A.
