The expression for the circumference of the circle is 2πr, where π is approximately 3.14 and the r is the radius of the circle, 1.4 inches. So the circumference of the circle is
. So the circumference of the circle is 8.792 inches.
Supplementary angles are those angles whose sum of the measures of angles is 180 degrees.
Observe the figure clearly.
1. are supplementary angles.
2. are supplementary angles.
3. are supplementary angles.
4. are supplementary angles.
5. are supplementary angles.
6. are supplementary angles.
Answer: m=3/2
.
Step-by-step explanation:Use the slope formula to find the slope
m
.
Answer:
You have to eliminate one of the variables when the equations are added.
A) x + 2y + z = 10
B) 2x -y +3z = -5
C) 2x -3y -5z = 27
We mulutiply A) by 2 then add it to B and C
A) 2x + 4y + 2z = 20 and the sum =
6x = 42 Luckily, the "y" and "z" variables cancel out and we find:
x = 7
Then we use x =7 in calcucating equation A) and B)
A) 2y + z = 3
B) -y + 3z = -19
THEN solve for y and z by eliminating variables.
