13 What is the equation of the line that has a slope of -3 and passes through the point (4,6)?

Mathematics

algol [13]3 years ago

Step-by-step explanation:

the general equation of a line is

y = ax + b

a is the slope of the line.

b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).

we get b by using the point coordinates in the equation and solve for b :

6 = -3×4 + b = -12 + b

18 = b

so, the full line equation is

y = -3x + 18

which is answer C : 3x + y = 18

What will be the value of median of a moderately asymmetrical distribution? If the mean and mode are 30 and 24 respectively.
sineoko [7]

The mean, the median and the mode are measures of central tendency, and they are related in some many ways, depending on the type of distribution.

The median of the moderately asymmetrical distribution is 26

The given parameters are:

Mean = 30

Mode = 24

For a moderately asymmetrical distribution, the mean, median and mode are related by the following equation:

Mode = 3 * Median - 2 * Mean

Substitute known values

30= 3 * Median - 2 * 24

30= 3 * Median - 48

Collect like terms

3 * Median =30+ 48

3 * Median =78

Divide both sides by 3

Median =26

Answer:

Combine like terms, although the provided answer is missing a "-" sign in front of the "13."  

Step-by-step explanation:

Combine like terms.  The -7 and -6 can be added to produce -13.

The correct result is <u>-</u>13 - 2x^2 = <u>-</u>2x^2 + 1  [Not _13- 2x² = _2x² + 1

Which expression represents 36x^2-100y^2 factored completely
Citrus2011 [14]
36 and 100 are both perfect squares
the factorization of x^2-y^2 is (x+y)(x-y)
substitute x^2 with 36x^2 and y^2 with 100y^2:
<span>36x^2-100y^2=
(6x+10y)(6x-10y) or 
4(3x+5y)(3x-5y)</span>
