Draw the graph of the equation<br><br> x+y=5

Advocard [28]

well first you have to get x and y on separate sides so subtract x by both sides to put x on the right side.

now you have y = 5 - x

to graph that let's throw in some numbers for x and y and make a function table

x, y

1, 4

2, 3

3, 2

4, 1

5, 0

6, -1

and so forth

as you can see as x increases in value, y decreases in value

all you have to do now is plot those points on a graph

How many 3 digit numbers can be formed from the digits 2, 3, 5, 6, 7 and 9 which are divisible by 5 and none of the digits is re

Number of 3 digit numbers can be formed from the digits 2, 3, 5, 6, 7 and 9 which are divisible by 5 and none of the digits is repeated is 20

A permutation is an act of arranging the objects or numbers in order. Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.

Given,

The digits = 2,3,5,6,7 and 9

The number should be divisible by 5 and the digits cannot be repeated

When the unit digit of the number is either 5 or 0, then the number will be divisible by 5.

Number of possible ways to fill the unit place = 1

Number of possible ways to fill the tens place = 5

Number of possible ways to fill the hundredth place = 4

Number of three digit number can be formed =4×5×1=20

Hence, the number of 3 digit numbers can be formed from the digits 2, 3, 5, 6, 7 and 9 which are divisible by 5 and none of the digits is repeated is 20
