What are the zeros for both functions

sammy [17]

Answer:

the zero of a function is the value of x which makes the final value zero

First Equation:

So let 25 - 2x equal to 0

<em>25 - 2x = 0</em>

x = 12.5

Second Equation:

Let 2x² - 11x - 6 equal to zero

<em>2x² - 11x - 6 = 0 </em>

<em>2x² - 12x + x - 6 = 0 </em><em>(Splitting the middle term)</em>

<em>2x(x - 6) + 1(x - 6) = 0</em>

<em>(2x + 1) (x - 6) = 0</em>

So we can transpose either one of the brackets below the zero

(2x + 1) = 0 or (x-6) = 0

x = -1/2 or x = 6

Graph each equation rewrite in slope-intercept form first if necessary.Y=-1/3x+4

kati45 [8]

To graph the linear equation, follow the steps below.

Step 01: Find one point of the line.

To do it, choose a x-value and find its corresponding y-value.

Let's choose x = 0.

Substituting x in the equation to find y:

$\begin{gathered} y=-\frac{1}{3}x+4 \\ y=-\frac{1}{3}*0+4 \\ y=0+4 \\ y=4 \end{gathered}$

First point: (0, 4).

Step 02: Find another point of the line.

Let's choose x = 3.

Substituting x in the equation to find y:

$\begin{gathered} y=-\frac{1}{3}*3+4 \\ y=-\frac{1}{3}*3+4 \\ y=-\frac{3}{3}+4 \\ y=-1+4 \\ y=3 \end{gathered}$

Second point: (3, 3).

Step 03: Plot the two points and connect them to draw the graph.

The graph is shown below:
