For which system of equations is (–2, 3) the solution? a. 3x + 2y = 0 4x + 3y = –1 b. –3x + 4y = –6 2x + 5y = 11 c. –x + 7y = 16 5x – 3y = 16 d. –x + 7y = 23 5x + 3y = –1

D. -x+7y=23, 5x+3y=-1

Step-by-step explanation:

Unfortunately, it seems you need to try the proposed solution in each of the answer choices to see what works.

___

A. 4(-2)+3(3) = 1 ≠ -1

B. -3(-2)+4(3) = 18 ≠ -6

C. -(-2)+7(3) = 23 ≠ 16

D. -(-2)+7(3) = 23; 5(-2)+3(3) = -1 . . . . the solution works in these equations

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
