Y = 3/5x + 1, 5y = 3x - 2, 10x - 6y = -4<br> is it perpendicular, parallel, neither

Ber [7]

Answer:

$y=\frac{3}{5} x+1$ and $5y=3x-2$ are parallel.

$10x-6y=-4$ is neither parallel nor perpendicular.

Step-by-step explanation:

First, you have to simplify each equation in terms of y.

$y=\frac{3}{5} x+1\\5y=3x-2\\10x-6y=-4$

Your first equation is already in terms of x, so simplify your second equation.

$5y=3x-2\\y=\frac{3}{5} x-\frac{2}{5}$

Now you can simplify your third equation.

$10x-6y=-4\\-6y=-10x-4\\y=\frac{5}{3} x+\frac{2}{3}$

These are your three equations in terms of y:

$y=\frac{3}{5} x+1\\\\y=\frac{3}{5} x-\frac{2}{5} \\\\y=\frac{5}{3} x+\frac{2}{3}$

Now, all you have to know is how to tell using your slope if a line is parallel or perpendicular to another.

Two parallel lines will have the exact same slope.

Two perpendicular lines will have slopes which are opposite reciprocals. For example, a line with a slope of 2 is perpendicular to a line with a slope of $-\frac{1}{2}$ , as they have opposite signs and are reciprocal (2/1 versus 1/2) to each other.

Your first two equations have the same slope and are therefore parallel.

Your third equation is a reciprocal, but it is not opposite, and is therefore not parallel nor perpendicular.

Which polynomial expression represents a sum of cubes? (6 – s)(s2 + 6s + 36) (6 + s)(s2 – 6s – 36) (6 + s)(s2 – 6s + 36) (6 + s)

Nadusha1986 [10]

Answer:

Option 3 is correct that is $(6+s)(s^2-6s+36)$

Step-by-step explanation:

We have general formula for sum of cube which is

$a^3+b^3=(a+b)(a^2+b^2-ab)$

Here, we have a=s and b=6

on substituting the values in the formula we will get

$6^3+s^3=(6+s)(s^2+6^2-6s)$

After simplification we will get

$6^3+s^3=(6+s)(s^2+36-6s)$

After rearranging the terms we will get

$6^3+s^3=(6+s)(s^2-6s+36)$ which exactly matches option 3 in the given options.

Therefore, option 3 is correct that is $(6+s)(s^2-6s+36)$

Answer:

16

Step-by-step explanation:

Each poster is 3 ft long divided that into 13 and you will get 4

each poster is 2 ht high divided that into 8.5 and you will get 4

4 posters high and 4 posters wide - 16

there will be .5 ft left high and 1 ft left long
