Answer:

3 is a function.

1 and 2 are not.

Step-by-step explanation:

1 and 2 are not functions because we can draw a vertical line which passes through  more than one point on the graphs.

You cant do this on graph 3 so it is a function.

Identify the correct slope and y intercept of the equation 2x + 4y = 12.
sertanlavr [38]

The standard form of a line is an easy way to solve for the properties of a line, such as slope and the intercepts. Take a line with the equation in standard form,

Ax + By = C

The slope here is given by y = -A/B.
The x-intercept here is given by (C/A, 0).
The y-intercept here is given by (0, C/B).

For this problem, the equation is 2x + 4y = 12. Thus,
slope = -2/4 = -1/2
y-intercept = (0, 12/4) = (0, 3)

A group of students went on a hike and measured the change in elevation over the length of the trail. They plotted these data on
Lyrx [107]
The correct answer for this question is this one: "<span>y = -x + 2"</span>

<span> y - intercept = (0,2) slope = -1

y = mx + b
2 = -1 (0) + b
b = 2

so the equation of the line is
<u>y = -x + 2</u></span>
Hope this helps answer your question and have a nice day ahead.

What is the product 3x5(2x2+4x+1)
lesya692 [45]

Answer:

6x^7+12x^6+3x^5

Step-by-step explanation:

The given expression is:

3x^5(2x^2+4x+1)

We expand the parenthesis using the distributive property to obtain;

3x^5(2x^2)+3x^5(4x)+3x^5(1)

Recall that;

a^m\imes a^n=a^{m+n}

We apply this property and multiply out the constant terms to obtain;

6x^7+12x^6+3x^5
