Answer:
Here is how it should look
Step-by-step explanation:
I cant see the image b, any way u can type it outp
Keywords:
<em>System of equations, variables, hardcover version, paperback version, books
</em>
For this case we must construct a system of two equations with two variables. Let "h" be the number of hardcover version books, and let "p" be the number of paperback version books. If the hardcover version of a book weighs 7 ounces and the paperback version weighs 5 ounces, to reach a total of 249 ounces we have:
(1)
On the other hand, if there are Forty-five copies of the book then:
(2)
If from (2) we clear the number of books paperback version we have:

As each paperback version book weighs 5 ounces, to obtain the total weight of the paperback version books, represented by "x" in the table shown, we multiply
So, 
Answer:

Option D
Answer:
<h2>B. 2x + y = 4</h2>
Step-by-step explanation:
Having the system of equations in its simplest form

If

then the system of equations has infinitely many solutions.
If

then the system of equations has no solution.
If

then the system of equations has one solution.
We have the equation

Convert to the standard form Ax + By = C<em>:</em>
<em />
<em> add 2x to both sides</em>

F(x) is the same as y. so you’d choose two coordinates and do y2-y1 over x2-x1. id recommend doing that with whole numbers, no decimals. by doing that you get your slope.
