In Algebra, a constant is a non-varying term- a number that is fixed and usually on its own.

In this case, it is 4.

Consider the line that passes through each pair of given points, and decide what type of slope the line has.

Answer:

The types of slope for each pair are:

(2, 4) and (5, 1) => Negative

(3,5) and (-1,2) => Positive

(-7, 8) and (-7,0) => Undefined

(6.-3) and (4, -3) => Zero

Step-by-step explanation:

We will find the slope of each line to check the type of slope.

Slope is given by the formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Here (x1,y1) are the coordinates of first point and (x2,y2) are coordinates of second point

Now,

(2, 4) and (5, 1)

$m = \frac{1-4}{5-2} = \frac{-3}{3} =-1$

The slope is negative.

(3,5) and (-1,2)

$m = \frac{2-5}{-1-3} = \frac{-3}{-4} = \frac{3}{4}$

The slope is positive

(-7, 8) and (-7,0)

$m = \frac{0-8}{-7+7} = \frac{-8}{0}$

division by zero makes the slope undefined.

(6.-3) and (4, -3)

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

The slope is zero

Hence,

The types of slope for each pair are:

(2, 4) and (5, 1) => Negative

(3,5) and (-1,2) => Positive

(-7, 8) and (-7,0) => Undefined

(6.-3) and (4, -3) => Zero

Answer:

m = 3

Step-by-step explanation:

Assuming these shapes are similar, you can set up a proportion:

$\frac{8}{12} =\frac{2}{m}$

→Cross multiply:

$\frac{8m}{24}$

→Divide 24 by 8:

m = 3

Answer:

The answer is: D. 6.9 x 10^5

Step-by-step explanation:

To find the answer, you simply need to convert the scientific notation into normal notation and then divide the largest value by the smallest value.

Scientific Notation Normal Notation

3.45 E 9 3,450,000,000

0.5 E 4 5000

Divide these values and you get:

Answer:

$-\dfrac{3}{5}$

Step-by-step explanation:

1. Find the numerator:

$\dfrac{1}{3}-\dfrac{5}{6}=\dfrac{1\cdot 2}{3\cdot 2}-\dfrac{5}{6}=\dfrac{2}{6}-\dfrac{5}{6}=\dfrac{2-5}{6}=-\dfrac{3}{6}=-\dfrac{1}{2}.$

2. Simplify the fraction:

$\dfrac{-\frac{1}{2}}{\frac{5}{6}}=-\dfrac{1}{2}\cdot \dfrac{6}{5}=-\dfrac{3}{5}.$
