3xy

h - 25 =< 14

Add '25' to both sides

h =< 14 + 25

h =< 39

NB Treat Inequalities like an 'Equals' except when multiplying negative numbers or fractions, whereupon , turn the sign around.

Verificstion

When h = 38

Substitute

38- 25 = 13 which is less than 14. as required.

When h = 40

40 - 25 = 15 > 14 So NOT True.

By the 'Chain Rule'

dy/dx = dy/du X du/dx

Y = Cos (pi*x).

Let pi*x = u

Y = Cos(u)

u = pi*x

dy/du = -Sin(u)

du/dx = pi

Hence

dy/dx = dy/du X du/dx => ( Chain Rule)

dy/dx = -Sin(u) X pi

Substitute u for pi*x

Hence

dy/dx = -Sin(pi*x) X pi

Tidying up

dy/dx = -piSin(pix) Done!!!!

Sine(pi/2) = 1

This is 'Radian' measure of an angle.

pi/2 radians = 90 degrees.

When you see something like 'Sine(pi/2)' make sure your calculator is in RADIAN mode. ' NOT degree mode.

One million is one thousand multiplied to one thousand.

1000^(2) = 1000 x 1000 = 1,000,000

A guinea, in UK currency, was worth 21 shillings or 1 pound and 1 shilling.

x^(2) - 36 =

x^(2) - 6^(2)

Remember two squared terms , as above, with a NEGATIVE between them can factor to

(x - 6)(x + 6)

NB

#1 ; The different signs in the brackets.

#2, Two squared terms with a POSITIVE (+) between them, does NOT factor.

#3 ; Inspect the constant, to see if it is a squared number ; 36 = 6^(2) in this case.

Well, isn't that a happy little question! The natural log of 100 is approximately 4.605. Just like painting a beautiful landscape, math can also create its own kind of beauty. Keep exploring the wonders of numbers and you'll uncover even more delightful surprises along the way.

The product of 7926 multiplied by 4 is 31,704. This can be calculated by multiplying the units digits first (6 x 4 = 24) and carrying over the tens place to the tens digit (2 x 4 = 8, plus the carried over 2 = 10). Then, multiply the tens digits (2 x 4 = 8) and add the carried over 1 from the previous step. Finally, multiply the hundreds digit (9 x 4 = 36) and add any carried over values.

im really sorry but this is the stupidest question question i have ever heard. if you are over 8 years old you should know how to do this. please learn basic math before asking some idiotic questions.

9/2... hope that helped.

---------------------------------

9 is an odd number (1,3,5,7,9,11 etc), odd numbers can not be divided by 2 exactly so you are always left with (0.5).

so 9/2=4.5

So the answer to your question is that 2 times 4.5=9

from bre2552: don't listen to him i f you dont know the answer then you need to fine someone else this website suppose to help not critize idiot fool

You want me to run three times a day, but how will that help me to make new friends?

365 x 40 is equal to 14,600. This can be calculated by multiplying 365 by 40, which is the same as adding 365 forty times. In other words, it represents the total when you have 365 groups of 40 items each.

first you divide both sides by 2 then add brackets in front of the number:

1. divide 8x+12= 4 and 6 divide again = 4 and 2 and 3

2. add brackets= 4{2x=3}

Hope This Helped

Ah, let's take a moment to appreciate the beauty of this equation. When we have y - 18, we are simply subtracting 18 from the value of y. It's like taking a peaceful stroll through the forest of mathematics, where each step brings us closer to understanding the harmony of numbers.

Then, y can be any value such that x = 0! If that equation doesn't contain y values, then this means that any y value work for the equation!

For instance, if y = 1, then x = 0. If y = 2, then x = 0 and so on.

1.08 is a fraction. It is a fraction in decimal form rather than in the form of a ratio. However, that does not stop it being a fraction. And, since it is a decimal fraction, there is not another simpler decimal form. Its equivalent, in rational form, is 108/100 which can be simplified to 27/25.

The expression x^2 - x represents a quadratic equation in standard form. It is a polynomial of degree 2, with x raised to the power of 2 and a coefficient of -1 for the linear term. This expression can be factored as x(x-1), which shows that it has two factors, x and (x-1). It is a parabolic function that opens upwards and crosses the x-axis at x=0 and x=1.

To simplify the number 830, we need to find the greatest common factor (GCF) between 830 and any other number. In this case, the number 830 is already in its simplest form because it cannot be divided evenly by any other number except 1 and itself. Therefore, 830 in simplest form remains as 830.

you would think it be would but infinity is not a number but a theory

so not being a number is can not be used with equations symbols like plus, minus, times etc.

Well, sweetheart, the integral of dV/V is simply ln|V| + C, where C is the constant of integration. So, in other words, the integral of dV/V is the natural logarithm of the absolute value of V, plus some boring constant. Math can be a real snoozefest, but hey, at least now you know the answer!

Unfortunately, limitations of the browser used by Answers.com 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. And using ^ to indicate powers (eg x-squared = x^2).

Cannot tell whether the equation was

y = -4x + 3

y = -4x - 3

y - 4x = 3

or something else.

The expression "negative x plus 3x" can be simplified by combining like terms. Negative x can be written as -1x, so the expression becomes -1x + 3x. When you combine -1x and 3x, you get 2x. Therefore, the simplified expression is 2x.

Oh, dude, like, totally! So, a term in math is like a single mathematical expression, right? And 3x is totally just one term because it's like, one number (3) multiplied by a variable (x). So, yeah, 3x totally qualifies as a term in math lingo.

x2 + 9x2 = 10x2
