Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Answer:
Step-by-step explanation:
A and B are along a straight line
(3x - 20) + 2x = 180
5x = 200
x = 40
3(40) - 20 = 100°
The fourth option is correct. 1. Switch f(x) for y 2. Transfer -10 as a +10 to the left side of the equation. y + 10 = 2x. 3. Then last, divide both sides by 2 to leave the x alone of the right. Now you have x = 1/2y + 5. Now switch back the y and x so it becomes y = 1/2x + 5. Also, make the y an h(x) to finish up.
