Ulleksa [173]

I am going to graph the situation on an external graphing utility and show you the answer, it will take a

minute, stay with me.

$m\text{ = }\frac{rise\text{ }}{\text{run}}=\frac{change\text{ in y}}{\text{change in x}}=\frac{3}{1}=3$ $y\text{ = mx+b}\rightarrow\text{ b =-1}$

So the equation of the line is.

$y\text{ =3x -1}$ $y\text{ -1 = m(3-0)}$

Which polynomial represents the difference 6x2+3x-8 and x2-3x+4

Semmy [17]

The difference will be
$6x^2+3x-8 - (x^2-3x+4) \\ =
6x^2-3x-8-x^2+3x-4 \\ =
5x^2 -12$ .
Remember that parentheses are needed for the second polynomial because the negative is distributed to all of its terms.

You buy a storage case that holds 170 collectible die-cast cars. You have 137 die-cast cars. Write an inequality that describes

Answer:

137 + x <= 170

Step-by-step explanation:

The following inequality will describe this scenario.

137 + x <= 170

the variable x in this scenario represents the total number of cars that you will purchase. This number is added to the number of toy cars that you already own which is 137. As long as this sum is less than or equal to 170 then your storage case will hold them.
