Calculus

the x's are -7's

The best way to break down a number (from the perspective of arithmetic!) is to write it as a product of its prime factors. For instance,

24 = 2 x 3 x 4

where x is the multiplication operator and of course 2, 3, and 4 are all prime numbers.

To get slope, you need to get the equation y = mx + b and tehn m is slope.

2x - 3y = 8

subtract 2x from both sides

-3y = -2x + 8

divide both sides by -3

y = 2/3 x -8/3

Ans: 2/3 is slope

5x = 1

To find the answer to this question, x needs to be isolated by itself on one side of the "=" sign. Divide both sides by 5 and you get

(5x)/5 = 1/5

5/5 is one, so the equation becomes

1x = 1/5

And the answer is:

x = 1/5

x2+12x-13=0

The factor of x2+12x-13 is: (x+13)(x-1)

So: x+13 = 0 or x-1 = 0

The answer is: x=-13 or x=1

f(x) = 2x²

f(x) = 136

→ 2x² = 136

→ x² = 68

→ x = ±√68

As the positive value is required, x = √68 ≈ 8.246

If the question was about 8x = 218, then x = 218/8 = 27.25.

If not, unfortunately, limitations of the browser used by WA means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc.

This question cannot be answered. You will have to give me the number to the square root.

a = ±sqrt(c^2 - b^2)

7x+3=10x-9(shift +3 & 10x)

7x-10x=-9-3(signs changed)

-3x=-12(divide both sides by -3)

x=4

2x-2 x 3

2x-6

Assuming the first x is a variable -- why did you assume that?

Besides that's not "the answer" it's just simplified.

All x mean multiply - none are written 2x, there's always a space

2 x -2 = -4; -4 x 3 = -12

-4x=7y-28

-4x+28=7y

-4x/7+4=y

A line with a y-int of 4 and a slope of -4/7

A derivative of the word "prophecy" is "prophetic," which is an adjective describing something that pertains to or predicts future events. Another derivative is "prophet," referring to a person who conveys messages or revelations believed to be from a divine source. Both terms are rooted in the concept of foretelling or revealing future occurrences.

The motion of a pendulum in water will be similar to what it is in air, except it will move more slowly and loose energy much more rapidly (unless something with some "power" is keeping it going). The speed of the pendulum should graph like a sine wave with the peaks and troughs denoting the endpoints of the travel of the pendulum in its arc. The slope of the curve at any point will represent the instantaneous acceleration. If the pendulum is released and no energy is put in from outside, the graph of the speed will diminish very quickly and dramatically.

Heart flutters or the feeling of missed heartbeats (everyone has them, but just doesn't feel it in some cases.) Over-exercising can cause this. There is caffeine in soft drinks and chocolate. Sometimes eating after 8 PM can produce heart flutters because of a chemical in possibly junk food. It would be a good idea to see your doctor and be sure you have no abnormalities of the heart. Don't risk not seeing you doctor. I'm sure you are OK, but your doctor can explain to you how the heart works and why you may be getting those heart flutters. Hormones also can cause heart flutters and young women to perimenopausal women and women in menopause can get these heart flutters or so-called missed heartbeats on quite a regular basis.

Solving for two unknowns (x and y) requires two independent equations.

x2 - 9x + 8 = (x-1)(x-8)

5x plus 3 does equal 3 plus 5x; commutative law.

The average is the sum of variables divided by their count. For an instance:

x = 6
y = 102
z = 9

The average will be

( 6 + 102 + 9 ) / 3 = 117 / 3 = 39
