How do you graph x-y-3=0

Mathematics
1 answer:
Neko [114]3 years ago
4 0

Answer:

see explanation

Step-by-step explanation:

To graph the line, we require 2 points

Find the intercepts, that is where the graph crosses the x and y axes

To find the x- intercept let y = 0 in the equation and solve for x

x - 3 = 0 ( add 3 to both sides )

x = 3 ⇒ (3, 0 ) ← x- intercept

To find the y- intercept let x = 0 in the equation and solve for y

- y - 3 = 0 ( add 3 to both sides )

- y = 3 ( multiply both sides by - 1 )

y = - 3 ⇒ (0, - 3 ) ← y- intercept

Plot the points (3, 0) and (0, - 3) and draw a straight line through them

The sum of three consecutive even numbers is one hundred sixty-two. what is the smallest of the three numbers?
givi [52]

Answer:

54

Step-by-step explanation:

The numbers are 54, 56 and 58 because 54 + 56 = 110 and 58 + 110 = 168. So lead to 54 being the smallest of the three.

Jude has 30 coins of quarters and nickels. The total amount he has is $5.10. How many of each coin does Jude have? Write the sys
Lyrx [107]

Answer: Required system

x+y= 30

0.25x+0.05y=5.10

Jude has 18 quarters and 12 nickels.

Step-by-step explanation:

Let x= Number of quarters

y= Number of nickels

As per given,

x+y= 30   (i)

0.25x+0.05y=5.10  (ii)   [1 quarter = $0.25 , 1 nickel = $0.05]

Multiply 0.25 on both sides of equation (i)

0.25x+0.25y= 7.5   (iii)

Eliminate (ii) from (iii) , we get

0.20y=2.4

⇒ y = 12  [divide both sides by 0.20]

Put value of y in (i\), we get

x+12=30

⇒ x= 30-12= 18

Hence, Jude has 18 quarters and 12 nickels.
