Answer:
3x + 2 =2x 3x = 2x - 2 3x - 2x = -2 x = -2 Proof: 3 * -2 + 2 = 2 * -2 -4 = -4
Step-by-step explanation:
Answer:
m∠CPD = 129.75°
Step-by-step explanation:
m∠APD + m∠APB = 180 since the angles are supplementary
x + 1 + 3x - 18 = 180
4x - 17 = 180
4x = 197
x = 49.25
m∠APB = 3(49.25) - 18 = 129.75
m∠APB = m∠CPD because the angles are vertical angles
m∠CPD = 129.75°
We can use the formula y2-y1/x2-x1 to find the slope.
1. 2-(-15)/12-5 gives us 17/7. The slope is 17/7.
2. -5-(-20)/6-(-18) gives us 15/24. We can simplify this to 5/8. The slope is 5/8.
3. -19-(-19)/-17-(-18) is 0/1. The slope is 0.
4. -17-3/-11-(-1) is -20/-10. The slope is 2.
