PLS HELP ME FIND THE ANSWER TO THESE 2 QUESTIONS PLEASE

lisov135 [29]

Answer:

Step-by-step explanation:

116f) 5 - |p + 6| = -8

|p + 6| = 13

p + 6 = 13 OR p + 6 = -13

p = 7 OR p = -19

In this case, I think you have to plot a point at 7 and -19.

116a) |7x| = 5

7x = 5 OR 7x = -5

x = $\frac{5}{7}$ OR x = $-\frac{5}{7}$

Again, I think you need to plot points at $\frac{5}{7}$ and $-\frac{5}{7}$ .

leonid [27]

Answer:

2, 16 and 256.

Step-by-step explanation:

Just substitute for n:-

first term ( when n = 1) = 2 * 2^(1-1)

= 2 * 1 = 2

4th term = 2 * 2^(4-1) = 16

8th term = 2* 2^(8-1) = 256
