The second choice is the answer
Answer:

Step-by-step explanation:
Since you are doing
squared, you have to multiply the exponents.
4 * 2 = 8

Answer:
x = 4, y = 1
(4, 1)
Step-by-step explanation:
-2x - y = -9
5x -2y = 18
-2x - y = -9
+2x +2x
-y = 2x - 9
/-1 /-1
y = -2x + 9
5x -2y = 18
5x - 2(-2x + 9) = 18
5x + 4x - 18 = 18
9x - 18 = 18
+ 18 + 18
9x = 36
/9 /9
x = 4
Now, we solve for y:
-2(4) - y = -9
-8 - y = -9
+ 8 +8
-y = -1
/-1 /-1
y = 1
(x, y) -> (4, 1)
Hope this helps!
Find the 10th term in the following arithmetic sequence if the constant being added is -12
Step-by-step explanation:
20 - 12 = 8
8 - 12 = -4
-4 - 12 = -16
So the sequence will be
20; 8; -4; -16
an = 20 - 12(n - 1)
a10 = 20 - 12(10 - 1) = -88
