Answer:
y = 25x - 300.
Step-by-step explanation:
This is a reasonable conclusion because we know that Steven earns $25 an hour, so it would be 25x. Since we know he pays rent, we are going to subtract that from 25x. Therefore, y = 25x - 300 is the answer.
A table (relation) may or may not represent a function
The table that represents a function is Hal's table
<h3><u>Tables and relations</u></h3>
For a table to represent a function, then the input values must point to exactly one output value.
This means that:
Each height entry must correspond to exactly one age entry
From the given tables (see attachment), we can conclude that
Hal's table represents a function
This is so because, the age entries on this table has one corresponding one height entry

$20 minus $15 = $5 difference
$5 divided by $0.20 = 25 checks
*Now the accounts are even, except I haven't done the checks for the second account.*
25 checks times $0.10 = $2.50
$2.50 divided by $0.20 = 12.5 checks (round up in this case to 13)
*Now, you need to do 13 more checks on the second account*
13 checks times $0.10 = $1.30
$1.30 divided by $0.20 = 6.5 checks (round up in this case to 7)
*Now, you need to do 7 more checks on the second account*
7 checks times $0.10 = $0.70
$0.70 divided by $0.20 = 3.5 checks (round up in this case to 4)
*Now, you need to do 7 more checks on the second account*
4 checks times $0.10 = $0.40
$0.40 divided by $0.20 = 2 checks
*Now, you need to do 2 more checks on the second account*
2 checks times $0.10 = $0.20
$0.20 divided by $0.20 = 1 check
*Now, you need to do 1 more checks on the second account*
1 checks times $0.10 = $0.10
$0.10 divided by $0.20 = 0.5 checks (round up in this case to 1)
*Now, you need to do 1 more checks on the second account*
1 checks times $0.10 = $0.10
$0.10 divided by $0.20 = 0.5 checks
25 + 13 + 7 + 4 + 2 + 1 + 1 = 53 checks
Check your work!
Account #1- $15 + (53 times $0.20) = $25.60
Account #2- $20 + (53 times $0.10) = $25.30
Answer
53 checks
Answer:
formulla of perimeter of rectangle
Step-by-step explanation:
perimeter of rectangle=2(l+b)
= 2(7.5+3.25)
=2(11.25)= 22.5
Answer:
The first one is proportional and the second one is not. Because for the first one you can see that if you divide the number of pens by the cost you'll get the same answer for every single one. But for the second one if you divide the number of minutes by words typed you get a different answer for each one. You can also see if it's proportional or not if you draw it on the graph and it's a straight line. If it is the relationship is proportional if it isn't it's not proportional. Hope that makes sense :)
