-5x + 3 + -32

=  -5x + (3 + -32)

=  -5x + (-29)

=  -5x - 29

19.        

Nice answer, shania....!!!

Either 19 or 21

If the equation is in the form:  y  =  a(x - h)² + k

then the vertex is the point (h, k) and the focal point is the point (h, k + 1/(4a)).

If you need further information, please repost with specific questions.

what is 7-c=-13

The slow but safe way:

7 - c = -13     [subtract (-) 7 from both sides]

-c = -20         [multiply (*) both sides by -1]

c = 20

The fast way:

7 - c = -13    [Remember that (a - b) = -(b - a), by using this ruse we get rid of the minus signs at once]

c - 7 = 13

c = 20 

2-3=-1

3/4+6/2+(-9/4) equal to 1.5 or as 1 1/2

2/9 divded by 4/5 plus 563/6000 equal to 0.372611111 so it must me be 0.37

9 + -9  =  0

0 + -7r  =  -7r

Since slope is defined to be "the change in y divided by the change in x", and the greek letter delta (Δ) is used to represent "change in", the formula for slope becomes:  m  =  Δy / Δx

When the slope is 4, m = 4 and this can be written as:  m = 4/1.

So, Δy = 4 and Δx = 1  --->  when x changes by 1, y will change by 4.

Starting at the point (a, b), when you change the x-value by 1, the x-value becomes a + 1; and when you change the y-value by 4, the y-value becomes b + 4.

(a, b)  -->  with a slope of 4  -->  (a + 1, b + 4)

Order of Operations Rules say:  do exponents before you do multiplication, divisions, additions, and subtractions, so:

1² - 4 x 5 x (-3)

=  1 - 4 x 5 x (-3)

Now the rules tell you do all multiplications and divisions -- in order, from left to right -- before you do any additions or subtraction:

=  1 - 20 x (-3)     (a negative times a negative is positive)

=  1 + 60

Now you can do additions and subtractions:

=  61

√(9 -3x) is as simplified as it can be.

Is there something you want to do with it?

To turn into a percentage, divide and multiply your answer by 100:

5/41  =  0.12195...   --->   12.195...%

(9.8 m/s²) / (1.17 m²/s)  =  (9.8/1.17) 1/m·s  =  8.4/(m·s)

A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (thenumber on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1.

                             4/3 b - 11  =  25

Add 11 to both sides:  4/3 b  =  36

Multiply both sides by 3:  4b = 108

Divide both sides by 4   :  b  =  27

CO₂ has 44 g/mole (Atomic weight of carbon atom = 12, that of oxygen atom = 16)

Avogadro's number is 6.0221415*10²³ molecules/mole

so there are (13.2/44)*6.0221415*10²³ molecules in 13.2 g of CO₂ 

$${\frac{{\mathtt{13.2}}}{{\mathtt{44}}}}{\mathtt{\,\times\,}}{\mathtt{6.022\: \!141\: \!5}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{23}}} = {\mathtt{180\,664\,245\,000\,000\,000\,000\,000}}$$

or 1.80664245*10²³ in total.

In each of these molecules there are two oxygen atoms, so double this.

.

(75 + 50) * 6 + 100 - 25 - 4 = 821

75 * (50 - 6) / 4 - 100 / 25 = 821

(100 + 50 - 25) * 6 + 75 - 4 = 821

(100 - 75) * (25 + 6)  + 50 - 4 = 821

(100 + 6 - 75) * 25 + 50 - 4 = 821

100 * (50 + 6) * 4 / 25 - 75 = 821

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

(75 * 50 - 100 - 2) / 8 - 25 = 431

(75 * (50 - 100 / 25) - 2) / 8 = 431

OK guys stop arguing

Very nice, Melody......I'm glad you figured this out.......this question WAS extremely confusing...!!!

Young studs, like you, would know all about little rods. You probably excel at finding them on line and in person.

Is the “To Catch a Predator” site part of your portfolio?

Spend some time on writing your "trolls posts" this "math site" is your only life anyway.

Those are like old people insult words. Come on go behind your limits use something more offensive you seem to be someone who has never seen and ever will see a p***y besides your moms, and will end up going back in it too when you find out nobody else wants to be a part of your little rod.
