Answer:
m∠BPD = 120
mBC + mAD = 120°
Step-by-step explanation:
according to intersecting chord theorem: The measure of the angle formed by two chords that intersect inside the circle is
the sum of the chords' intercepted arcs.
m∠BPD =
(M∠BD + M∠CA)
=
(70 + 170)
=
(240)
m∠BPD = 120
We know that a circle has a total of 360° around the center of circle. To find the measure of the remaining measure of angle of arcs, subtract them from the whole that is 360°
mBC + mAD = 360 - ( 70 + 170 )
= 360 - 240
mBC + mAD = 120°
4x²y + 24x² - 24y - 144 can be written as :
4x²(y + 6) - 24(y + 6)
(y + 6)(4x² - 24)
(y + 6) is the factor of 4x²y + 24x² - 24y - 144
Answer:
x ≈ 15.9
Step-by-step explanation:
a straight line is equal to 180 degrees
so we now know that 9x + 8 + 29 = 180
combine like terms 9x + 37 = 180
now subtract 37 from both sides 9x = 143
now divide both sides by the value of 9 x ≈ 15.9

What is the solution to a system of linear equations?
If you have a system of equations that contains two equations with the same two unknown variables, then the solution to that system is the ordered pair that makes both equations true at the same time.
The system of equations
y = -3x + 6 ...................(1)
y = 9 .................(2)
Substitute equation (2) in equation
9 = -3x + 6
subtract both sides
9 - 6 = -3x + 6 - 6
3 = -3x
Divide by -3 both sides
x = -1
the solution is the point ( -1, 9 )
Therefore,the solution to the system of equations is the point ( -1, 9 ).
