Please help me with these!
1) A super ball is dropped from a height of 100 feet. Each time it bounces, it rebounds half the distance it falls. In feet, how high will the ball travel on its seventh bounce problems!

2) The fifth term of an arithmetic sequence is 9 and the 32nd term is -84. What is the 23rd term?

3) How many terms of the arithmetic sequence 88, 85, 82, . . . appear before the number -17 appears?

1 1/5

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
