Use Photomath for the rest
Answer:
k = ½
Equation => 
Step-by-step explanation:
Constant of proportionality (k) = y/x
Using a point on the graph, (6, 3),
k = y/x = 3/6 = ½
k = ½
Equation of the line:
Plug in the value of k into 
(slope-intercept form of equation for proportional relationship)
Thus:
Hey there!
Since there are 12 months in a year, we divide 48,048 by 12 to get how much he earned per month.
After calculating this, we find that he earned:
4,004 dollars per month.
Hope this helps!
5x+2y=20 when x=3/10 is:
5(3/10)+2y=20
15/10+2y=20
1.5+2y=20
2y=18.5
y=9.25
The number of books owned by frank is represented as b < 150
<h3>What is inequality?</h3>
Inequality represents the form of writing expressions where the left hand side of the expression is not exactly equal to the right hand side of the expression
<h3>How to represent the required expression</h3>
Information gotten from the data include
Emily has 300 books
Frank were to double the number of books that he now owns, he would still have fewer than Emily has.
Let the number of books owned by frank be b and from the information we have that:
2b < 300
b < 150
hence the number of books owned by frank, b less than 150
