Line CD passes through points (0, 2) and (4, 6). Which equation represents line CD?
Vikentia [17]
(0,2)(4,6)
slope = (6 - 2) / (4 - 0) = 4/4 = 1

y = mx + b
slope(m) = 1
use either of ur points (0,2)...x = 0 and y = 2
sub and find b, the y int

What is the value of the expression
Y_Kistochka [10]

Answer:

0.8

Step-by-step explanation:

We begin with the expression: 0.5+(-\frac{3}{4} )+0.25-(-\frac{4}{5} )

First, we need to convert the fractions into decimals to make this easier.

-\frac{3}{4}=-0.75 and -\frac{4}{5} =-0.8

Once we have this, we can simplify it

0.5-0.75+0.25-(-0.8)\\\\0.5-0.75+0.25+0.8\\\\0.75-0.75+0.8\\\\0.8

118,813,760 different combination license plates can the country produce

<h3 /><h3>permutations and combinations:</h3>

permutations and combinations, the various ways in which objects from a set may be selected, generally without replacement, to form subsets. This selection of subsets is called a permutation when the order of selection is a factor, a combination when order is not a factor. By considering the ratio of the number of desired subsets to the number of all possible subsets for many games of chance in the 17th century, the French mathematicians Blaise Pascal and Pierre de Fermat gave impetus to the development of combinatorics and probability theory.

given that

in a certain country license plates consist of zero or one digit followed by four or five uppercase letters from the roman alphabet

X = 10 × 26 × 26 × 26 × 26 × 26

  = 10 × 11881376

  = 118,813,760

118,813,760 different combinations license plates can the country produce
