What is the slope of the line represented by:
5x-12y = 24
Answers
Answer:
5/12
Step-by-step explanation:
5x - 12y = 24
~Subtract 5x to both sides
-12y = 24 - 5x
~Divide -12 to everything
y = -2 + 5/12x
~Reorder
y = 5/12x - 2
Slope is represent by "m" in slope intercept form [ y = mx + b ]. As we can see m = 5/12 from the given information.

Troy is considering two lawn care services. Premier Landscaping charges $15 for travel to Troy's house and $55 per hour for maintaining his lawn. Ace Landscaping does not have a travel fee, but charges $65 per hour for lawn maintenance. Part A Write a system of equations that represent the lawn care services.
Answers
Answer:
Cost for Premier Landscaping = [tex]55h+15[/tex]
Cost for Ace Landscaping = [tex]65h[/tex]
Where [tex]h[/tex] is the number of hours spent on lawn care.
Step-by-step explanation:
Given that:
Charges as per Premier Landscaping:
Fixed charges for travel to the house = $15
Per hour charges = $55
Let [tex]h[/tex] be the number of hours for which lawn care is done.
So, Charges for [tex]h[/tex] hours = Per hour charges [tex]\times[/tex] Number of hours =$55[tex]h[/tex]
Therefore, total cost = [tex]55h+15[/tex]
Charges as per Ace Landscaping:
Per hour charges = $65
Let [tex]h[/tex] be the number of hours for which lawn care is done.
Then Charges for [tex]h[/tex] hours = Per hour charges [tex]\times[/tex] Number of hours =$65[tex]h[/tex]
Therefore, system of equations that represent the lawn care services:
Cost for Premier Landscaping = [tex]55h+15[/tex]
Cost for Ace Landscaping = [tex]65h[/tex]
[tex]h>0[/tex]
Where [tex]h[/tex] is the number of hours spent on lawn care.

PLEASE help me!!! I need help with this problem below.... what is the rule for the sequence 1.8, 2.85, 3.90, 4.95, 6 Please answer this with a clear step by step explanation before tomorrow And help me out! Thanks!
Answers
Answer:
The next term is equal to the previous term with an added 1.05.
Step-by-step explanation:
The given sequence is:
1.8, 2.85, 3.90, 4.95, 6
The first term is:
[tex]a = 1.8[/tex]
The second term is:
[tex]a_2 = 2.85[/tex]
The third term is:
[tex]a_3 = 3.90[/tex]
The fourth term is:
[tex]a_4 = 4.95[/tex]
The fifth term is:
[tex]a_5 = 6[/tex]
Let us have a look at the difference of each term:
Second term - First term = 1.05
Third term - Second term = 1.05
Fourth term - Third term = 1.05
Fifth term - Fourth term = 1.05
We can see that there is a common difference between each term of the given sequence.
Therefore, we can conclude that:
The given sequence is an Arithmetic Progression which has the difference of each term as equal.
First term, [tex]a = 1.8[/tex]
Common difference, [tex]d =1.05[/tex]
So, the rule is:
The next term is equal to the previous term with an added 1.05.
