Answer:

1st pic answer:

Slope= -3

Parallel slope= -3

Perpendicular slope = 1/3

2nd pic answers:

1 and 2 are parallel

1 and 3 are perpendicular

2 and 3 are perpendicular

Step-by-step explanation:

To find the slope in your first equation (6x+2y=1) you need to get y alone so that your equation will be in slope-intercept form (y=mx+b).

6x+2y=1     Start by subtracting the 6x over to the other side.

-6x      -6x

2y= -6x+1   Next divide by 2 to get y completely alone.

\frac{2y}{2} =\frac{-6x}{2}+\frac{1}{2}

y= -3x+1/2

So to answer the first part your slope is -3. Parallel slope would be the same as your regular slope. Perpendicular would be the opposite, so that means you have to flip it and change the sign.

-3 flipped is -1/3

if you change the sign it becomes positive giving you 1/3

Part 2

Your first step would be to get all the equations into the slope-intercept form (y=mx+b). The second one is already in the form so we only need to change 1 and 3.

3y=5x+2   To get y alone you need to divide everything by 3.

\frac{3y}{3}=\frac{5x}{3} +\frac{2}{3}

y=5/3x+2/3  Before we work on equation 3 we can go ahead and compare equations 1 and 2.

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

2: y=\frac{5x}{3} +7   Since 1 and 2 have the same slope they would be parallel.

Now to change equation 3.

6x+10y=8    Start by subtracting the 6x over to the other side.

-6x       -6x

10y=-6x+8     Now divide everything by 10 to get y alone.

\frac{10y}{10}=\frac{-6x}{10} +\frac{8}{10}

y=-6x/10+8/10   Now we need to simplify the fractions using common factors. I'm going to use 2 for both equations, so you take -6 and 10 both divided by 2, which gives you -3 and 5(-3x/5). Now do the same with the other fraction. 8 and 10 divided by 2 gives us 4 and 5 (4/5)

3: y=\frac{-3x}{5}+\frac{4}{5}

2: y=\frac{5x}{3} +7

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

Since three has an opposite slope of both 1 and 2 it would be perpendicular to both.

Help no troll answer plz
stealth61 [152]

Answer:

Step-by-step explanation:

<u><em>Q 4.</em></u> (25m + 25m) ÷ 25 sec. = <em>2 m/sec.</em>

<u><em>Q 5.</em></u> This question belongs to Physics and not Mathematics!!!

Wavelength (lambda) = Velocity (v) ÷ Frequency ( sec^{-1} or Hz )

f = v / (lambda)

f = 3 / 2 = <em>1.5 (Hz)</em>

<u><em>Q 6.</em></u> 0.060 ÷ 2 = <em>0.030 m</em>

If y is proportional to x and y = -15 when x = -20, what is the value of x when y = 12?
Alex
When y=-15, x=-20. So subtract x from y, you will get that y= 0 and x=-5. Add 12 to both and you have your answer, x=7 and y=12
