Answer:
Step-by-step explanation:
In finding the COMMON DIFFERENCE, subtract the 2nd term and the first term.
a1 = -4
a2 = -2
Let "d" representing the COMMON DIFFERENCE.
d = -2 -(-4)
d = -2 + 4
d = 2
ANSWER:
THE COMMON DIFFERENCE OF THIS SEQUENCE IS 2
The equation of the polar curve
is an even cosine function.
<h3>Polar curves</h3>
In geometry, polar curves are curves that are represented by the polar coordinates such that they are drawn around a fixed point
The equation of the polar curve is given as:

To graph the polar curve, we make use of the following representations:
- r represents the y-axis
represents the x-axis
Using the above representation, we can graph the polar curve
See attachment for the graph that represents

Answer:
B. y =
Step-by-step explanation:
I. Given x = 15 and y = 4
4 = 
4 = 2+2
4 = 4 true
II. Give x = 0 and y = 2
2 = 
2 = 0 + 2
2 = 2 true
III. Given x = -15 and y = 0
0 = 
0 = -2 + 2
0 = 0 true
Good luck.
Answer:
-21 =x
Step-by-step explanation:
3x – 10 = 5x + 32
Subtract 3x from each side
3x-3x – 10 = 5x-3x + 32
-10 =2x +32
Subtract 32 from each side
-10 -32 = 2x+32-32
-42 = 2x
Divide each side by 2
-42/2 = 2x/2
-21 =x
