Answer:

  (x, y) = (-2, 1)

Step-by-step explanation:

Equate the two expressions for y.

  -5x -9 = 2x +5

  -14 = 7x . . . . . . . .add 5x-5

  -2 = x . . . . . . . . . divide by 7

Then ...

  y = 2(-2) +5 = 1

The solution is (x, y) = (-2, 1).

Which pair of equations can be used to solve for x in PQR?
almond37 [142]

Answer:

A

Step-by-step explanation:

sin57° = \frac{opposite}{hypotenuse} = \frac{PQ}{PR} = \frac{x}{18}

∠ P = 180° - (90 + 57)° ← sum of angles in triangle

∠ P = 180° - 147° = 33° , then

cos33° = \frac{adjacent}{hypotenuse} = \frac{PQ}{PR} = \frac{x}{18}

Thus the 2 ratios used to solve for x are A
