How do you simplify x^2+y^2?

2 answers:

The other responder is correct. There is nothing more to be done.

You may think this is a trivial response, but it is a good one. It teaches you not to destroy plus signs by combining unlike terms. You should treat this as a "can you combine apples and oranges" problem.

In other words, is there any similarity between apples and oranges other than both are fruits? You should answer no there is no similarity.

Same with xs and ys. There is no similarity. until you are told there is.

Answer<<<<< nothing can be done.

Nothing further can be done, its x^2+y^2

a map distance of 5 inches represents 200 miles of actual distance. suppose the distance between two cities on the map is 7 inch

Eva8 [605]

Set up a proportion:

5/200 = 7/x

Cross multiply:

200 * 7 = 5 * x

1400 = 5x

Divide 5 to both sides:

x = 280

Write the equation of the line in fully simplified slope-intercept form.

Bad White [126]

Answer:

$y = -\frac{2}{5} x-6$

Step-by-step explanation:

1) First, find the slope of the line. Use the slope formula $m =\frac{y_2-y_1}{x_2-x_1}$ . Pick two points on the line and substitute their x and y values into the formula, then solve. I used the points (-5,-4) and (0,-6):

$m = \frac{(-6)-(-4)}{(0)-(-5)} \\m = \frac{-6+4}{0+5} \\m = \frac{-2}{5} \\$

So, the slope of the line is $-\frac{2}{5}$ .

2) Next, use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation of the line in point-slope form. (From there, we can convert it to slope-intercept form.) Substitute values for the $m$ , $x_1$ and $y_1$ into the formula.

Since $m$ represents the slope, substitute $-\frac{2}{5}$ in its place. Since $x_1$ and $y_1$ represent the x and y values of one point on the line, pick any point on the line (any one is fine, it will equal the same thing at the end) and substitute its x and y values in those places. (I chose (0,-6), as seen below.) Then, with the resulting equation, isolate y to put the equation in slope-intercept form:

$y-(-6) = -\frac{2}{5} (x-(0))\\y + 6 = -\frac{2}{5} x\\y = -\frac{2}{5} x-6$

A piece of string is cut in half, so thata one half can be used to bundle newspapers for recycling. One thrid of the remaining s

lutik1710 [3]

The whole string was 2.4m. If you take 1/3 of 1/2x, you are just taking 1/6x. You know that what remains is 2m, and that it's the remaining 5/6. So you divide 2 by 5 and multiply that by six to get 2.4.

Convert (CAB) 16 to decimal<br><br>need help asap

Mrrafil [7]

Remark

So CAB is a base 16 number? I hope that's correct. I'll treat it that way. If I am incorrect, please leave a note and I'll modify my answer accordingly.

Expand

A = 10 in decimal

B = 11 in decimal

C = 12 in decimal

B is the "units" value in decimal it is 11

A is the "tens" value or 12 place and in decimal you would get 12 * 10 = 120

C is the "hundreds" value or 12^2 place and in decimal you would get 144*12 =1728

Now you need to all all three results together. 11 + 120 + 1728 = 1850

Answer

(CAB)_16 = 1850 in decimal
