Answer:
false in all cases
Step-by-step explanation:
1) they are not supplementary ,cuz sum is not 180
2) false,cuz sum is not 90°
3) measure of AOB is not 60° and OC not bisecting them
4) measure of AOB is not 60° and OB not bisectijg AOC

Answer:
2.7
Step-by-step explanation:
point 1 = ( -1 , 5 ) point 2 = ( 5 , -5 )
equation of a line: y = mx + b
Find Slope (m):
( 5 - (-5)) / (-1 - 5))
= 10 / -6
= -3 / 2
slope = -3/2
Find y-intercept (b):
y = mx + b
y = -3/2 * x + b
5 = -3/2 * -1 + b <-------------- use the x and y coordinate of one of the . points. I used point 1 ( -1 , 5 )
b = 7/2 or 3.5
Assemble:
y = -3/2 * x + 3.5
Answer:
It's option D. 8(8x + 9y).
J Multiply the first equation by 3
F Add the two equations and solve for x
G x = -3
B Substitute the value of x in the first equation, y = 1
C the solution is (-3, 1)
