Step-by-step explanation:
here's the solution,
in the given figure , sum of all angles formed with O measures 360°
because, it forms a complete angle
so,
=》mPOQ + mQOR + mROS + mSOT + mTOP = 360°
=》mPOQ + mQOR + mROS + mSOT + mTOP = (90° × 4)
=》mPOQ + mQOR + mROS + mSOT + mTOP = 4 × right angle
(cuz.. right angle = 90°)
Answer:
y = -29/19 and x = -44/19
Step-by-step explanation:
3x + 2y = -10 multiply by -2 ⇔ -6x - 4y = 20
2x - 5y = 3 multiply by 3 ⇔ <u> 6x - 15y = 9 </u>
Add the two equation -19y = 29
y = -29/19
Use equation one and solve for x
3x + 2(-29/19) = -10
3x - 58/19 = -10
3x = -10 + 58/19
3x = -190/19 + 58/19
3x = (-190 + 58)/19
3x = -132/19
x = - 132/ 19 ÷3
x = -44/19
20+6x=32
subtract 20 from 20 and 32
6x=12
6x/6=12
6 cancels out
x=2
Answer:
y = -3x - 9
Step-by-step explanation:
Point-slope equation for line of slope -3 that passes through (-2,-3):
y+3 = -3(x+2)
Rearrange equation to slope-intercept form
y+3 = -3x - 6
y = -3x - 9
