Answer:
15, 8, 25 The teacher payed 0.40 per book.
Step-by-step explanation:
4/10 = 2/5 Simplify the 4/10 to find the unit rate.
15: 2/5 = 6/x Set up your proportion.
2x =30 Cross multiply
/2 /2 Divide both sides by 2 to isolate x
x =15
8: 2/5 = x/20 Set up proportion
40 =5x Cross multiply
/5 /5 Divide both sides by 5 to isolate x
8 =x
25: 2/5 = 10/x Set up proportion
2x =50 Cross multiply
/2 /2 Divide both sides by 2 to isolate x
x =25
Graph: y=mx+b To graph, you will need to use y=mx+b format
y= 2/5 x+2 2/5 is your unit rate. Your rate changes every 2 books bought. To graph, start at (0,2) and go up 2 and to the right 5, plot. Continue moving up 2 and to the right 5 to graph.
The teacher payed 0.40 per book because 2/5 simplifies to 0.40.
D= 23 in.
hope its what you’re looking for :)
Answer:
x=32 hope it helps, if it does can i get 5.0 or brainliest
Step-by-step explanation:
When leading coefficient is 1 , the root will be an integer for g(x) = 0
Option 4 is the right answer.
<h3>What is a Polynomial Function ?</h3>
Functions of independent variable in which the variable can appear more than once with different powers.
Let this represents the polynomial function
where 
Then the according to rational root theorem ,
The root of the function is given by
So when leading coefficient is 1 , the root will be an integer for g(x) = 0
Option 4 is the right answer.
