Answer:

-2 < x < 4.5

Step-by-step explanation:

Step 1: Add 1 to all parts/sections.

$-5+1$
$-4$

Step 2: Divide all parts/sections by 2.

$\frac{-4}{2}$
$-2 < x < 4.5$

Therefore, the range of possible values of x is -2 < x < 4.5.

A sequence can be generated by using an=an−1+9, where a1=−5 and n is a whole number greater than 1. What are the first four term

kotegsom [21]

Answer:

A

Step-by-step explanation:

For the sequence, the defining formula is given as;

an = Previous term + 9

So a2 will be -5 + 9 = 4

a3 will be 4 + 9 = 13

a4 will be 13 + 9 = 22

a5 will be 22 + 9 = 31

So the sequence of numbers will be;

-5, 4 , 13 , 22 , 31

Both 52 and 5x-8 are equal to each other due to being parral.
SO 5x-8=52

Add both sides.
8+8 52+8= 60

5x 60
Now divide both sides by 5 and you get 12=x Hope this helps!
