The relationship between two numbers is described below, where x represents the first number and y represents the second number. the square of the first number is equal to the sum of the second number and 16. the difference of 4 times the second number and 1 is equal to the first number multiplied by 7. select the equations that form the system that models this situation. then, select the solution(s) of the system. equations solutions y2 + 16 = x (2x)2 = y + 16 (1,15) (5,9) x2 = y + 16 7y - 1 = 4x (2,-12) (8,48) 1 - 4y = 7x 4y - 1 = 7x (4,-7) (9,3) nextreset

x^2=y+16

4y-1=7x

(5,9)

Step-by-step explanation:

The condition says:

The square of first number is equal to the sum of the second number and 16:

Lets say that the first number is 'x' and the second number is 'y'. So the square of 'x' is and that is equal to the sum of second number i.e y and 16:

Second condition says that:

The difference of 4 times the second number and 1 is equal to the first number multiplied by 7:

4 times the second number is and difference of 1 is:

and this is equal to 7 times the first number:  

So the two equations are:

it can be to see completed examples before writing, in order to examine what makes for an effective piece. see how these intros give some context before posing the topic and lead naturally into the body paragraphs, where the evidence will be listed. you can imagine how the author has organized the rest of the piece.

"we buried my cousin last summer. he was 32 when he hanged himself from a closet coat rack in the throes of alcoholism, the fourth of my blood relatives to die prematurely from this deadly disease. if america issued drinking licenses, those four men—including my father, who died at 54 of liver failure—might be alive today. that is a good example piece   some steps that are .

. writing something that happened to you

.read a book you like to get ideas from there

. lastly you can make a venn diagram

hope this plz make brainliest
