Make sure that they are connected correctly to the computer and make sure that they are plugged in to the right compartment. Check and see if they are plugged into the outlet(that you plug everything in like lamps and phones and vaccums and what not)... And you should probably turn them on :)

0. A line with constant y-value is horizontal, so its gradient is 0, meaning it neither goes up nor down.

(1+x)/(x^2+1)

Let x^2+1 =u

2x dx = du

x dx = du/2

(1+x) / (x^2+1) = 1/(x^2+1) + x / (x^2+1)

Integral of x dx / (x^2+1) = (1/2) integral du / u = 1/2 ln|u| --(1)

Integral of 1 / (x^2+1) = arctan(x) --(2)

Adding (1) and (2)

Integral (1+x)/(x^2+1) = (1/2) ln(x^2+1) + arctan(x) + C

x=4

y=x+3

y=4+3

$36.50 if she just keeps it in a jar or a piggy bank. More if she invests it.

Not calculus. In the case of having a plus sign in front of a minus sign, the result is to subtract the number. The same goes for if you have a minus sign in front of a plus sign. Remember that if the signs are different, the result will be a subtraction, if the signs are the same, it will be an addition (ie a double negative (- -), or a double positive(+ +)). So this question, 26 + -3 -11 is the same as 26 -3 -11, so will equal 12.

I will be glad to give you a complex number. (i^i)^i is i raised to the i power and

raised to the i power again. This is not the same as i^3 which is -i but computes to .947 + .321i

7X + 4 - 2X + 9 = 0

Move all constants to the opposite side-

7X - 2X = -9 - 4

Simple addition and subtraction-

5X = -13

Get X by itself by division-

X = -13/5

There you go :)

What is n??

Please answer

The answer is 0. In algebra, the multiplication symbol is not used, as it would be too commonly mistaken for the letter x, which looks the same, but serves a completely different purpose. Algebra, is in short, just a way of substituting numbers for letters, to make complicated sums and equations seem more manageable. If x equals 0 and y equals 1, then it is just another way of saying 0 x 1, which is obviously 0, because 0 lots of anything, is always 0.

2x+y = 8

y = -x+5

Substitute y for -x+5 into the first equation:

2x+(-x+5) = 8

2x-x+5 = 8

x = 8-5

x = 3

Substitute the value of x into the original equations to find the value of y:

x = 3 and y = 2

12(b + 1)(b + 1)

Adding a negative number and positive number lowers the positive number. So, since you're taking 2 away from 5, the 5 goes down to 3. Therefore, the answer is 3.
