-2y + 2
Explanation
We have (x - y + 1) - (x + y - 1)
Let’s expand the Parentheses
= x - y + 1 - x - y + 1
Then let’s group the like terms
= (x - x) + (- y - y) + (1 + 1)
= 0 - 2y + 2
= 2y + 2

the long picture will be part 1 and the small pic is the second part
Answer:
C), or y = 200(1.18)^x, because we have 200 bacteria to start with and 1.18 because if you multiply something by 1.18 that is essentially 118% more than the number, or 18% more than the number.

Using the slope concept, it is found that the shuttle traveled 3.2 miles while Marion was watching.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.
Initially, the angle of elevation is of 16º, with an elevation of 1 mi, hence:
Then, at the end, the angle will be of 74º, with the elevation remaining constant, hence:
The distance is:
The shuttle traveled 3.2 miles while Marion was watching.
