Answer:

y=1/3x-7/2

Step-by-step explanation:

First get the 2y by itself by adding 2/3x to both sides. Then subtract both sides by 2.

Y=1/3x-7/2

To do this put equation in y=mx+b

Answer:

y=-2x-4

Step-by-step explanation:

y-y1=m(x-x1)

y-0=-2(x-(-2))

y-0=-2(x+2)

y=-2x-4+0

y=-2x-4

A train traveled 3/5 of the distance between two cities in 1/4 of an hour. At this rate, what fraction of the distance between t

Mkey [24]

Answer: 2 2/5 distance

Step-by-step explanation:

You know 1/4 of an hour you travel of 3/5 of distance, so let’s set an proportion: 1/4 hr = 3/5 of distance, multiply 4 on both sides, and you get 2 2/5 distance. Hope this helps!

Can you please show me how you got the answer (50 points)

Answer:

$4x^{6}2y^{-2}$

Step-by-step explanation:

We can use a property I like to call SEi-F. (Subtract Exponents in a Fraction)

But first, there is an exponent outside of the parentheses in both places. We can use the Power of Parentheses to simplify and then use the SEi-F.

We will start with the x in the numerator.

3*4 = 12

Now for the y in the numerator.

4*4 = 16

Our new numerator is $4(2x^{12}y^{16})$

We do need to simplify the numerator one more time to get rid of the 4 outside the parentheses.

We will start with x's coefficient.

2*4 = 8

Now for y's coefficient.

1**4 = 4

*y seems to have no coefficient, but if so, it has a coefficient of 1. This applies to other variables.

Our final simplified numerator is $8x^{12}4y^{16}$ .

Repeat with the denominator.

Try it yourself!

Make sure that when you finish, you finish the fraction.

After completing the denominator, your completed fraction should be:

$\frac{8x^{12}4y^{16}}{4x^{6}2y^{18}}$

Now we can use the SEi-F to complete the problem.

Start with x.

8x - 4x = 4x

12 - 6 = 6

The first term is $4x^{6}$ .

Now for y.

4y - 2y = 2y

16 - 18 = -2

The second term is $2y^{-2}$

The complete, simplified equation is $4x^{6}2y^{-2}$ .

I could be wrong on the answer, but the work should be correct.

Hope this helps. Have a nice day. Oh, and one more thing. Surprised I'm not stealing points?
