Answer:
Step-by-step explanation:
To find inverse you switch x and y and solve for y.
y = (9/2)x - 5
switching gives
x = (9/2)y - 5
x+5 = (9/2)y
(2/9)(x+5) = y
Answer:
∠ A = 140° , ∠ B = 30° , ∠ C = 10°
Step-by-step explanation:
the sum of the 3 interior angles = 180°
sum the given angles and equate to 180
x - 5 + 2x + 140 = 180
3x + 135 = 180 ( subtract 135 from both sides )
3x = 45 ( divide both sides by 3 )
x = 15
then
∠ A = 140°
∠ B = 2x = 2 × 15 = 30°
∠ C = x - 5 = 15 - 5 = 10°
Both sides were multiplied by 3 to get Step 1, so the property is the Multiplication Property of Equality. Choice D.
