Hey there! I'm happy o help!
To get from 60 to -20, you multiply by -1/3. This is our constant of proportionality. Let's see which points below follow this.
-10(-1/3)=3 1/3≠30
30(-1/3)=-10≠-15
-30(-1/3)=10
80(-1/3)=-26 2/3≠-30
Therefore, the correct answer is (-30,10).
Have a wonderful day! :D

Answer:
D. 43 degrees
Step-by-step explanation:
The sum of angles in a triangle is 180°. If x represents the measure of the third angle, then ...
75° +62° +x = 180°
137° +x = 180° . . . . . . . . . collect terms
x = 180° -137° = 43° . . . . subtract 137° from both sides of the equation
The third angle measures 43°.
-2x+6=-8+10x

x=7/6
Answer:
C = StartFraction pi times 4 over 2 EndFraction.
Step-by-step explanation:
the circumference of a circle=
C= 2 times PI times radius
Radius= d/2
sooo it is
C = StartFraction pi times 4 over 2 EndFraction.
