Answer:

C

Step-by-step explanation:

A function passes the vertical line test. This graph passes it so it is a function.

A one to one function has a single output for each input. This has multiple outputs for some inputs. Therefore, it is not one to one.

Given that J is between H and K. If JK=3x-1, HJ=2x+4, and HK=12, find x and JK.

Answer:

X=7

Step-by-step explanation:

HJ + JK = HK

3(X + 2) +(3X - 4) = 44

3X + 6 + 3X - 4 = 44

6X + 2 = 44

6X = 42

X = 7

Write an equation in slope intercept form that goes through (-1,6) and (3,-2)

pochemuha

<h2>Answer:</h2>

First, we need to use <u><em>slope formula*</em></u> to find the slope.

$m = \frac{-2 - 6}{3 - (-1)} = \frac{-8}{4} = -2$

Second, we use the slope we found and <em>ONE</em> of the 2 points listed and plug it into <u><em>slope-intercept form**</em></u> to solve for <u><em>b</em></u>.

Here is what we have so far:

$m = -2$

I'm going to use this point:

$x = 3$

$y = -2$

Here is how to find <em>b</em>:

$-2 = -2(3) + b\\\\-2 = -6 + b\\\\4 = b$

Finally, we put all of it together and we have our equation.

$y = -2x + b$

*Slope formula: <em>m = y₂ - y₁/x₂ - x₁</em>

**Slope-intercept form: <em>y = mx + b</em>

<em></em>
