Answer:
4X+50=150
-50 on both sides
4x=100
divided by 4 on both sides
x=25
Step-by-step explanation:
Answer:
4th option
Step-by-step explanation:
The relationship is linear,
putting the value of x in the right side of the equation of option 4, you'll get the value of the left side
putting, x=1
y+4=-1/2(x-1)
y=-1/2(1-1)-4
y=-4
putting, x=7
y+4=-1/2(7-1)
y=-1/2(6)-4
y=-6/2-4
y=-3-4
y=-7
A isnt correct because radius goes from center of circle to any point on circle. Chord on the other hand connects 2 points on circle...
B is also false. Secant goes through circle while tangent only touches it in one point.
C is correct. Chord connects as said before 2 points on circle and in some cases it can connect 2 points in such way that it goes through center which is diameter.
D is not correct because chord doesnt have to pass trought center of circle in order to connect any 2 points on circle.
