-7x + 12 is not an equiv. expression because one of the - signs in the original expression has been changed to +.
Answer:

Step-by-step explanation:
Arc BC is the intercepted arc for the central angle COB, so its measure is the <u>same</u> as the central angle.
Angle 2 is an inscribed angle, so its measure is <u>half</u> the measure of the intercepted arc BC.
Angles 3 and 4 are congruent inside an isosceles triangle (OB = OC, both radii), and the sum of all angles in triangle COB is 180 degrees, so
180 - 32 = 148 (sum of angles 3 and 4)
Each of angles 3 and 4 measure half that remaining 148 degrees.
Angle 5 is one of two congruent angles in an isosceles triangle AOC (OA = OC) so its measure is that of angle 2.
Hello,
1) y-8=(8-2)/(4-2)(x-2) ==>y-8=3(x-2) (not in answer!)
2) y-2=3(x-2) ==> Answer A.
It is 1.51 and the one is repeating because all you do is subtract these, and you get a repeating answer.
Answer:
13/3 ÷ (-5/6)
Step-by-step explanation:
(4 1/3) / (-5/6)
(13/3) / (-5/6)
13/3 ÷ (-5/6)
