Answer:

Vertical.

Step-by-step explanation:

It is vertical because 4 + 4 (adding both X-axis, totalling 8) is smaller than 9 + 2 (adding both Y-axis, totalling 11), so the Y-axis, which is vertical, is bigger.

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?

Write the equation of a line perpendicular to the line y = 2x - 3 that goes through point (4, 3)

iragen [17]

Answer:

y = -1/2x + 5

Step-by-step explanation:

To get the perpendicular line first, take the negative reciprocal of the slope.

2 -> -1/2

So far, the equation is y - -1/2x ± b. (since we are using mx + b)

Since you want the point (4, 3) to cross over the line, we substitute values in.

3 = -1/2(4) + b

3 = -2 + b

b = 5

Your equation that fits the answer is -1/2x + 5.

Your welcome!

Convert the angle 0 = 70° to radians.

xxMikexx [17]

Answer:

7/18π radians Exact answer

1.22 radians Decimal approximation

Step-by-step explanation:

π radians = 180º

70 * π/180 = 7/18π

7/18 * 3.14159 ≈ 1.22
