The linear combination method gives a solution of (-4, 2) for which of these systems of linear equations

3x +13y = 14

6x +11y = -2

Step-by-step explanation:

Substitute the given values into the equations and see which equations are satisfied.

• first set:

3(-4) +13(2) = -12 +26 = 14 . . . . true

6(-4) +11(2) = -24 +22 = -2 . . . . true

You have the answer at this point, but you can check the other choices if you wish.

___

• second set:

4(-4) +5(2) = -16 +10 = -6 ≠ 12 . . . . second set of equations is not the answer

___

• third set:

5(-4) +4(2) = -20 +8 = -12 ≠ 12 . . . . third set of equations is not the answer

___

• fourth set:

10(-4) +3(2) = -40 +6 = -34 ≠ 8 . . . . fourth set of equations is not the answer

Since the Ferris wheel model is in feet and inches, bring both measurements to inches, then divide the total height of the Ferris wheel by the height of the model, then you multiply the height of the sky needle ride by the quotient of the height of the Ferris wheel and the model of the Ferris wheel to get 7 inches
