-5. The function of x is just a different way of saying y= blah blah. Since all points on a line are related by an equation, you need a function to find out where the point lie if the plane.
The first thing we are going to do is distribute:
=<span>4x+(6)(3x)+(6)(−2)
</span>=<span><span><span><span>4x</span>+<span>18x</span></span>+</span>−<span>12
</span></span>Second thing we are going to do is C<span>ombine Like Terms:
</span>=<span><span>4x+18x</span>+<span>−<span>12
=</span></span></span><span>(<span><span>4x</span>+<span>18x</span></span>)</span>+<span>(<span>−12</span><span>)
</span></span>And your final answer is:
<span>22x</span>+<span>−<span>12</span></span>
I hope this helps you! :)
Step-by-step explanation:
The equation of a parabola with focus at (h, k) and the directrix y = p is given by the following formula:
(y - k)^2 = 4 * f * (x - h)
In this case, the focus is at the origin (0, 0) and the directrix is the line y = -1.3, so the equation representing the cross section of the reflector is:
y^2 = 4 * f * x
= 4 * (-1.3) * x
= -5.2x
The depth of the reflector is the distance from the vertex to the directrix. In this case, the vertex is at the origin, so the depth is simply the distance from the origin to the line y = -1.3. Since the directrix is a horizontal line, this distance is simply the absolute value of the y-coordinate of the line, which is 1.3 inches. Therefore, the depth of the reflector is approximately 1.3 inches.

'-5'
Step-by-step explanation:
The table is a linear function. This means that all the points have a consistent slope. If two points had a different slope, it would be a nonlinear function.
Slope is rise over run. We are given the points (-3,0) and (-2,-5).
