Answer:
-12
Step-by-step explanation:
x-9.37+5.77=1.3x
It is 8
As a result of multiply 1.6 times 6, we would also need to apply it to the side as well, and therefore multiply it.
Answer:
y=6
Step-by-step explanation:
use elimination by making the ys opposite in value and eliminating them from the equation so there is only variable:
-3x+2y=6
2(4x-y=2)
-3x+2y=6
8x-2y=4
Combine like terms and divide by 5 on both sides.
5x=10
x=2
Plug x in to find y:
4(2)-y=2
8-y=2
y=6
The correct works are:
.
<h3>Function Notation</h3>
The function is given as:

The interpretation when Steven is asked to calculate Blue(s + h) is that:
Steven is asked to find the output of the function Blue, when the input is s + h
So, we have:

Evaluate the exponent

Expand the bracket

So, the correct work is:

<h3>Simplifying Difference Quotient</h3>
In (a), we have:


The difference quotient is represented as:

So, we have:

Evaluate the like terms

Evaluate the quotient

Hence, the correct work is:

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
