Answer:
(1,2) is a solution to both equations
Step-by-step explanation:
To determine if (1,2) is a solution to both equations, substitute into the equation and see if it is true
2x+y =4
2(1) + 2 =4
2+2 =4
4=4
true
y =3x-1
2 = 3(1) -1
2 =3-1
2=2
true
Since both statements are true
(1,2) is a solution to both equations
I think the domain and range are infinite
Answer:
The answer is: B) Yes, this is a valid inference because it took a random sample from the neighborhood.
And apart from the random sample, 40% of families agreed with her to attend the parade at least.
Step-by-step explanation:
Given:
Ratio of tulips to roses = 2:1
Total number of flowers = 18
To find:
The number of tulips.
Solution:
Let the number of tulips and roses are 2x and x respectively.
According to the question,


Divide both sides by 3.


Now,
Number of tulips 

Therefore, the number of tulips is 12.
