what is 3.35 x 10^25 times 1.9 x 10^9=6.365 x 10^34

44km in an hour. an hour=60 min 60/x=15  x=60/15=4  4*15=60 44/4=11 11km in an 15 min if it has constant speed 

2+-7+9+5+-4+6

whats -8 divided by -4x

\({\color{red}\frac{-8}{-4y}}{\color{blue}\ =\ \frac{2}{y}}\)    !

(7 4/5) / (3/5)  =  (39/5) / (3/5)  =  (39/5) x (5/3)  =  13

There is a total of 200 students.

120 students are male                       --->  80 students are female

50 are upper division student            --->  150 are lower division students

40 are upper division male students --->  10 are upper division female students

                                                               --->   80 are lower divison male students

                                                               --->   70 are lower division female

The probability of selecting a lower division student given the student is a female:

                 =  70 / 80  =  0.875

2x+3y=10

\(y=-\frac{2}{3}x+\frac{10}{3}\)

            p           q

\(if \ \ y\ =\ 0 \ then\)

\(-\frac{2}{3}x+\frac{10}{3}=0\)

Put the equation in slope-intercept form by isolating the "y."  Then you can either graph it starting with the y-intercept as your initial point and using rise/run...or make a table of values by choosing values for x (input, domain) and calculating the y values (output, range), then graph the ordered pairs, (x,y), from the table.

The point-slope formula is:  y - y₁  =  m(x - x₁)

For your problem:  m = 8     x₁ = -4     y₁ = -6

Placing these values into the formula:  y - -6  =  8(x - -4)

                                                                   y + 6  =  8(x + 4)

                                                                   y + 6  =  8x + 32

                                                                         y  =  8x + 26

                              or:                               8x - y  =  -26

Type in abs(x) to find the absolute value of x

.

Any number (positive or negative) that is whole, like 1 or -4. An example of a non-integer would be something like 4.5 or pi. Good luck.

X=6/tan31

Depends on the value of x

I think that you have to be a member to post images  [but, I'm not sure !!!  ]

If it's

790+x=360  subtract 790  from both sides

x = -430

If it's

790 + x = 180   subtract 790 from both sides

x = -610

log _2/3 [ 400 / 81 ] + 2 [ log₃ (4) - 1] [ log₃ (5) - 1] =

log (400/81) / log(2/3) + 2 [ log₃ (4) - 1] [ log₃ (5) - 1]  =

what is 17.5% of £3.20

what is 17.5% of £3.20

17.5/100 x 3.20 =0.56 pennies

log (2x^2 + 3x)  = log (6x + 2)

Since the bases are the same, we can solve for the anti-logs

2x^2 + 3x  = 6x + 2     rearrange as

2x^2 + 3x - 6x - 2   = 0    simplify

2x^2 - 3x - 2   = 0      factor

(2x + 1) (x  - 2)    =  0     set each factor to 0  and we get the possible solutions of  x = -1/2   or x = 2

Reject  x = -1/2 since it would result in taking the log of a negative number on both sides

Then.......x = 2 is the only  (real) solution 

The domain of the equation on the left  would be  (-inf, -3/2) U (0, inf)

The domain of the equation on the right would be (-1/3, inf)

Since we must choose the most restrictive interval, the domain for both functions is (0, inf)

Examples  and explanation

0.25  x  0.3      =   0.075.    Multiply the two whole numbers together to get 25 x3 = 75. Now where to put the decimal point?  The rule for where to put the decimal point is   ---   the  total number of digits after the decimal point is the same on both sides of the multiplication. There is a total of 3 digits ,or numbers, after the decimal points on the left hand side  that is  two from 0.25  and one from 0.3.   So there must be 3 digits after the decimal point on the right hand side,to get 0.075.

Another one

0.04 x 0.3          4 x 3  = 12.     There are 3 digits altogether after the decimal point on the left hand side,so there have to 3  on the right.  So we get   0.04  x 0.3   = 0.012.

Same rule every time,here's another two examples.

1.3   x  0.3    =  0.39

2.7   x  0.02 = 0.054
