How to divide integers

Alona [7]

I got this I hope this is helpful. To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer:
The product of two positive integers or two negative integers is positive.
The product of a positive integer and a negative integer is negative.

WILL MEDAL help me if please

nordsb [41]

1. Use the FOIL method (x+9)(x+9)
First, outer, inner, last
$x^{2} +9x+9x+81$
Add your like terms
$x^{2} +18x+81$

2. When you add or subtract polynomials you add or subtract the like terms and then put them in order from largest to smallest exponents.

3. $-5x(5 x^{3} +10 x^{2} -6x+3)$

4. Since it is the perimeter, we add the 3 together.
$(2 x^{2} +4x-3)+(-3 x^{2} -3)+(5x+19)$
Add the like terms together:
$2 x^{2} +(-3 x^{2} )=- x^{2} \\ 4x+5x=9x \\ -8+(-3)+19=8$
Put them in order of exponents
$- x^{2} +9x+8$

Hope this helps

67. The line contains the point (4,0) and is parallel to the line defined by 3x = 2y.

olganol [36]

Answer:

$y=\frac{3}{2} x-6$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form:

$y=mx+b$ where m is the slope of the line and b is the y-intercept (the value of y when the line crosses the y-axis)

Parallel lines will always have the same slope but different y-intercepts.

1) Determine the slope of the parallel line

Organize 3x = 2y into slope-intercept form. Why? So we can easily identify the slope, m.

$3x = 2y$

Switch the sides

$2y=3x$

Divide both sides by 2 to isolate y

$\frac{2y}{2} = \frac{3}{2} x\\y=\frac{3}{2} x$

Now that this equation is in slope-intercept form, we can easily identify that $\frac{3}{2}$ is in the place of m. Therefore, because parallel lines have the same slope, the parallel line we're solving for now will also have the slope $\frac{3}{2}$ . Plug this into $y=mx+b$ :
