How can you use properties of operation to solve problems?

MAXImum [283]

First of all not to be rude, but it is order of operations not properties of operations. Second, you can solve equations by going in the order of PEMDAS or Parentheses, Exponents, Multiplication, division, addition, and subtraction. Multiplication and division are switchable, addition and subtraction. If you do not follow this order you get the equation or inequality wrong.

Find the slope of the line: x/-1 + y/6 = 1

pychu [463]

The slope-intercept form: y = mx + b

m-the slope

$\dfrac{x}{-1}+\dfrac{y}{6}=1\\\\-x+\dfrac{y}{6}=1\ \ \ \ |add\ x\ to\ both\ sides\\\\\dfrac{y}{6}=x+1\ \ \ \ |multiply\ both\ sides\ by\ 6\\\\y=6x+6\\\\\\Answer:\boxed{The\ slope\ m=6}$

find a function whose second derivative is y''=12x-2 at each point (x,y) on its graph and y=-x+5 is tangent to the graph at the

pogonyaev

Start by integrating y'' twice to get function y(x).

$y' = \int (12x - 2) dx = 6x^2 -2x + c \\ \\ y = \int (6x^2 -2x+c )dx= 2x^3-x^2 +cx+d$

Next find value of coefficients 'c' and 'd' using the given tangent line
The slope of tangent line is equal to y' when x=1.

$6x^2 -2x+c = -1, x = 1 \\ \\ 6-2+c = -1 \\ \\ c = -5$

The tangent line intersects the curve y(x) when x = 1.
If x = 1, then y = 4 (From y =-x+5)

$y = 2x^3 -x^2-5x +d , x = 1, y = 4 \\ \\ 2-1-5+d = 4 \\ \\ d = 8$

Final Answer:
$y = 2x^3 -x^2 -5x+8$
