Line D.

That is because the line is going downwards so the slope is negative and it is going down one and right 2 so the slope is -1/2

Estimate the following sum by clustering.

Kryger [21]

The answer would be 60. By rounding, 14.2=14; 15.51=16; 14.99=15; 15.8=16.
14+15+16+16=61
Rounding: 61=60

The coordinates of AB are A(-5, -1) and B(-2, -6). If AC : CB = 3 : 7, what are the coordinates of point C?

navik [9.2K]

$\text{Let the coordinates of AB are }A(-5,-1), \text{ and }B(-2, -6)\\
\\
\text{let the coordinate of th point C be (x, y), such that}\\
\\
AC:CB=3:7\\
\\
\text{By the section formula, we know that if P(x,y) lies on a line segment AB}\\
\text{where, }A(x_1,y_1), \ B(x_2,y_2)\text{ and satisfy the ratio, }AP:PB=m:n, \text{ then}$

$P=\left ( \frac{mx_2+nx_1}{m+n}, \ \frac{my_2+ny_1}{m+n} \right ).\\
\\
\text{So using this formula, we get for the given problem}\\
\\
C=\left ( \frac{3(-2)+7(-5)}{3+7}, \ \frac{3(-6)+7(-1)}{3+7} \right )\\
\\
\Rightarrow C=\left ( \frac{-6-35}{10}, \ \frac{-18-7}{10} \right )\\
\\
\Rightarrow C=\left ( \frac{-41}{10}, \ \frac{-25}{10} \right )\\
\\
\Rightarrow C=\left ( -4.1, \ -2.5 \right )$

Coordinates of the point C is: (-4.1, -2.5)

Which of the following is a trinomial with a constant term.

Sunny_sXe [5.5K]

<h2>The "option d: $y^5$ + 13x + 12" is a trinomial with a constant term.</h2>

Step-by-step explanation:

To check options:

a: x + 4y

Here, the coefficient of x = 1 and the coefficient of y = 4

b: $x^3$

Here, the coefficient of $x^3$ = 1

c: $x^4$ + 3 $y^2$ + 2y

Here, the coefficient of $x^4$ = 1, the coefficient of $y^2$ = 4 and the coefficient of y = 2

d: $y^5$ + 13x + 12

Here, the coefficient of $y^5$ = 1, the coefficient of x = 13 and

constant term = 12

Thus, the "option d) $y^5$ + 13x + 12" is a trinomial with a constant term.

What does it mean to state the domain and range of a relation? Please answer, I am confused and it is due tomorrow. 30 points wi

Anastaziya [24]

The domain is all of the x values in a set and the range is all of the y-values in a set.
If you have a bunch of points such as (3,6), (7,2), (1,5) the domain would be stated as D={3, 7, 1} and the range would be stated as R={6,2,5} If you have a line, then the domain and range would be set up differently. For example, if you have a line with end points at (-3,2) and (5,8) then the domain would be D=(-3,5) and the range would be R=(2,8)
