You first slice for y on the first equations, then use the point slope formula which is y-y1=m(x-x1) it’s parallel because it had the same slope

-3x+5y=-4
5y=3x-4
Y=3/5x-4/5


When it parallel to the line y=3/5x-4/5

It can be y=-3/5x+b

-5=6/5+b

B=-5-6/5=-25/5-6/5=-31/5

Y=-3/5x-31/5

3/5x+y=-31/5

Multiply 5

3x+5y=-31

vovangra [49]

Answer:

The answer is a well designed experiment.

Step-by-step explanation:

When possible, the best way to establish that an observed association is the result of a cause and effect relation is by means of - well designed experiment.

Cause and effect relation is a relation between events, where one is the result, due to the occurrence of others. A well designed experiment takes place when we consider the cause and effect of events.

What are the intercepts of the line 2x + 4y = 12?
Darina [25.2K]
<span>if you're finding the x intercept, y is ALWAYS 0, so in this, you can just get rid of the -4y because you know that it's 0, so you're left with 2x=12 divide by 2 on both sides so you find x intercept is (6,0) on the graph 
the y works the same way, if you're looking for the y, you know that the x is zero, so you're left with -4y=12, divide by -4y on both sides and you end up with the y intercept being (0,-3) 

x int.= (6,0) 
y int.= (0,-3) 

by the way, when it's written like that, it's called standard form, so to find the intercepts on 2x=12+4y, you'd have to convert it into standard form (Ax=By=C) so you subtract 4y on both sides to make it 2x-4y=12, and then once you have it like that you can do the math to find the y and x intercepts.

If light travels at 3. 108 m/s and its frequency is 6. 1015 Hz, then its wavelength is:
Sergio039 [100]

Answer:

5 * 10^{-8} m

Step-by-step explanation:

The speed of light is 3 * 10^8 m/s and its frequency is 6 * 10^{15} Hz.

The speed of light is given as:

c = λ * f

where λ = wavelength of light

f = frequency of light

Therefore, the wavelength is given as:

λ = c / f

=> λ = \frac{3 * 10^8}{6 * 10^{15}}

=> λ = 5 * 10^{-8} m

The wavelength of the light is 5 * 10^{-8} m

Find the circumference and the area of a circle with diameter 2 cm.
ivolga24 [154]

Answer:

c = 6.28cm

area \:  = 3.14 {cm}^{2}

Step-by-step explanation:

circumferece \\  = 2\pi \: r \\  = 2 \times 3.14 \times 1 \\  = 6.28cm

area = \pi {r}^{2}  \\  = \pi \times 1 \times 1  \\  = 3.14 {cm}^{2}
