Answer:
50
Step-by-step explanation:
All angles around a circle is 360°
/_ 2 = 130°
/_ 1 = 130° (Vertically opposite angles)
= 130° + 130° = 260°
all angles = 360°
= 360° - 260° = 100°
= 100° ÷ 2
= 50°
= /_ 3 and /_ 4 = 50°
Verification = 130° + 130° + 50° + 50° = 360°
Answer:
y= -3x-1
Get the slope from the equation by getting y by its self then dividing everything by -1, which gives you y=-3x-12. You the -3 as your slope when doing the point-slope form.
Answer:
C
Step-by-step explanation:
The domain of this function is ![[-4,2]](https://tex.z-dn.net/?f=%5B-4%2C2%5D)
, as it is shown in the graph that 
is only within this interval. The range of this function is ![[-4,4]](https://tex.z-dn.net/?f=%5B-4%2C4%5D)
, as the smallest value of 
is -4 and the largest value of is 4, and takes every possible values between them.
I'm pretty sure it would be y=2x+9
Answer:
x = 4.5
y = -5
Step-by-step explanation:
2x - 3y = 24 2x + y = 4
y = -2x + 4
2x - 3(-2x + 4) = 24 y = -2(4.5) + 4
2x - (-6x + 12) = 24 y = -9 + 4
2x + 6x - 12 = 24 y = -5
8x - 12 = 24
8x = 36
x = 4.5
