Answer: C

\left \{ {{a_{1}=4 } \atop {a_{n}=a_{n-1}*(-3)  }} \right.

Step-by-step explanation:

The starting amount (a1) = 4

The rate is -3 because 4 * -3 = 12 and -12 and -12 * -3 = 36 etc.

Answer: C.

Step-by-step explanation:

The first number is a positive 4, which is your a1. Then the geometric sequence goes to a negative implying that it is multiplied by a negative. So the a1 = 4 and it is being multiplied by a negative 3.

Hey there!

h(x) = 17 + x/6
y = 17 + x/6
y = 17 + (-18)/6
y = 17 - 18/6
y = 17/1 + (-18)/6
y = 17/1 + (-3)/1
y = 17/1 - 3/1
y = 17 - 3 / 1 - 1
y = 14 / 1
y = 14
h(x) = 14


Therefore, the answer should be: 14



Good luck on your assignment & enjoy your day!

2(x+5)+6x = 8x+10 One Solution No Solution Many Solutions
Mama L [17]

Step-by-step explanation:

2(x + 5) + 6x = 8x + 10

2x + 10 + 6x = 8x + 10

8x + 10 = 8x + 10

Since this equality is true for any real values of x, there are infinitely many solutions for x.

The best answer here is "Many Solutions".
