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:
