Explain, in writing, the steps in graphing and finding the solution to the system of equations.
Anna11 [10]

Answer:

Feel free to copy and paste:

Use the slope-intercept form to find the slope and y-intercept. To do this, use y=mx+b. Plug the variables where m=1 and b=2. Slope of the line is m and y-intercept is value of b, so the slope is 1 while the y-intercept is (0,2). Any line can be graphed using two points, and using two x values to plug them into the equation to find the corresponding y values: 0=x+2 is (-2,0). Y-intercept is already known, so use the known values and make a table where x= -2,0 and y = 0,2. Now, graph the line using the slope, y-intercept, and known points (-2,0), (0,-2) to plot the graph. Coincidingly, the answer to solve your system of equations will be the x-intercept: (-2,0).

Can some answer this math question
-BARSIC- [3]

Answer:

A

Step-by-step explanation:

To multiply powers of a variable, add the exponents:

x^m\cdot x^n = x^{m+n}

This rule works for all exponents, positive, negative, or zero.  Also, remember that x^0=1.

Also, remember the definition of negative exponent:  x^{-n} = \frac{1}{x^n}

To multiply the two monomials, start by multiplying the coefficients, 14 and 4.  That gives 56, so your answer begins with 56.

Now for the powers of x,  (x^3)(x^{-5}) = x^{3+(-5)} =x^{-2} = \frac{1}{x^2}

For the powers of y,  (y^{-4})(y^4)=y^{4+(-4)} = y^0 = 1(y^{-4})(y^4) = y^{-4+4} = y^0 =1

Your answer is

56 \cdot \frac{1}{x^2} \cdot 1 =\frac{56}{x^2}
