2x + 6y = 14y - 19x^2 + 12 is a non-linear equation
Step-by-step explanation:
Lets define a linear equation first.
A linear equation is an equation in which there is no variable with exponent greater than 1 or the degree of the equation is 1.
So,
<u>x + 12 = -8x + 10 - 2y</u>
The equation is a linear equation because the degree of the equation is 1.
<u>x = 8x + 19 - 10y</u>
The equation is a linear equation because the degree of the equation is 1.
<u>2x + 6y = 14y - 19x^2 + 12</u>
The equation involve a term with exponent 2 which makes the degree of the equation 2 making it a quadratic equation
<u>2x + 13y + 14x - 7 = 16y - 3</u>
The equation is a linear equation because the degree of the equation is 1.
Hence,
2x + 6y = 14y - 19x^2 + 12 is a non-linear equation

Answer:
140 toy cars
Step-by-step explanation:
The ratio of Ed's toy car to Pete's toy car is initially given as 5:2
Ed gave Pete a total number of 30 cars
Let x represent the greatest common factor that exists between both number
Number of Ed's car is represented as 5x
Number of Pete car is represented as 2x
Since they each have an equal number of cars which is 30 then we can solve for x as follows
5x-30=2x+30
Collect the like terms
5x-2x= 30+30
3x= 60
Divide both sides by the coefficient of x which is 3
3x/3=60/3
x=20
Ed's car is 5x, we substitute 20 for x
5(20)
= 100 cars
Pete car is 2x,we substitute 20 for x
2(20)
= 40 cars
Therefore, the total number of cars can be calculated as follows
= 100+40
= 140 toy cars
Hence they have 140 toy cars altogether
Answer:
So the possibilities are
$12 and $ 0 , $9 and $ 3 , $6 and $6
Step-by-step explanation:
Given:
Total Magazines = 2
Price = $ 12
To Find:
Possible Prices of magazines = ?
Solution:
As it is given that Prices of magazines is multiples of 3
So
Multiples of 3 up till 12 are
0, 3 , 6 , 9 , 12
Now
Total Price of magazine is $12
Now The possible prices of the magazines are
First Possibility:
If price of first magazine is $12 then second would be $0 (free)
First possible price $12 and $0
Second Possibility:
If price of first magazine is $9 then second would be $3
Second possible price $3 and $9
Third Possibility:
If price of first magazine is $6 then second would be $6
Third possible price $6 and $6
So the possibilities are
$12 and $ 0 , $9 and $ 3 , $6 and $6
