Answer:
4 books
Step-by-step explanation:
The cost for one used = $2.27
The question requires you to find the number of books that could be purchased with $10
Let assume the cost for a single used book to be $ t
If you have $ x in your pocket then the number of books you can purchase with $ x will be;
number of books= $ x/ $t.............................(a)
Applying this expression to the question;
$t= $2.27
$ x= $10
number of books = $10/$2.27 = 4.405 = 4 books
Because 44 is a bigger number than 4 it is 11 times bigger so the difference is larger than a proportional number
<u><em>Answer:</em></u>
y^2 = 28x
<em><u>Step-by-step explanation:</u></em>
Since the directrix is horizontal, use the equation of a parabola that opens left or right.
(y−k)^2 = 4p(x−h)
Find the vertex.
(0,0)
Find the distance from the focus to the vertex.
p = 7
Substitute in the known values for the variables into the equation
(y−k)^2 = 4p(x−h).
(y−0)^2 = 4(7)(x−0)
Simplify.
<em>y^2 = 28x</em>
Answer:
12y + 120
Step-by-step explanation:
<u>First of, what is the distributive property?</u>
The distributive property is the property that helps distribute numbers under the parenthesis.
For example, lets use {x+1}4. You distribute the 4 towards the x and the one like this:
4(x) + 1(4)
4x + 4
Now, let's go back to your problem
<u>Solution:</u>
{y+10}12
12(y) +12(10)
= 12y + 120
