Answer:

<h2>The first graph doesn't represent a function.</h2>

Step-by-step explanation:

When we need to deduct from a graph if it's a function or relation, we use the vertical line proof.

The vertical line proof consists in drawing a vertical line on the function.

If the line intersect two points of the graph, then, the graph belongs to a relation.
If the line intersect only one point of the graph, then, the graph belongs to a function.

Therefore, the first graph is not a function, because if we draw a vertical line, it will intersect two points of the graph.

Answer:

The first graph.

Step-by-step explanation:

To determine whether or not a line is a function or not, you can use something called the vertical line test. If it fails the vertical line test, then it is not a function.

elena-s [515]

Answer:

Step-by-step explanation:

Let X be number of woodland bicyles and Y grande expedition

Our objective is to maximize profit

Z = 250x+350Y

Constraints are: 2x+3y<450 and

x+y<375

(given)

Solution gives negative y. Hence intersecting point is not within constraint.

So choices satisfying the constraints would be min of 225, 375 for x and min of 150,375 for x

i.e x=225 and y =150

To maximize revenue 225 Woodland and 150 Grande to be produced

Find the equation of this line. y= [?]x+[?]

DochEvi [55]

Answer:

$y=3x-4$

Step-by-step explanation:

Hi there!

Slope-intercept form: $y=mx+b$ where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x=0)

<u>1) Determine the slope (</u><u><em>m</em></u><u>)</u>

$m=\displaystyle\frac{y_2-y_1}{x_2-x_1}$ where two points that fall on the line are $(x_1,y_1)$ and $(x_2,y_2)$

On the graph, two points are highlighted for us: (0,-4) and (2,2). Plug these into the formula:

$m=\displaystyle\frac{2-(-4)}{2-0}\\\\m=\displaystyle\frac{2+4}{2}\\\\m=\displaystyle\frac{6}{2}\\\\m=3$

Therefore, the slope of the line is 3. Plug this into $y=mx+b$ :

$y=3x+b$

<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>

$y=3x+b$

Recall that the y-intercept occurs when x=0. Given the point (0,-4), the y-intercept is therefore -4. Plug this into $y=3x+b$ :

$y=3x+(-4)\\y=3x-4$

I hope this helps!
