How can -6.75 + (10.25) be expressed as the sum of its integer and decimal parts
ArbitrLikvidat [17]

Answer:

 -6.75 + (10.25)    =  ( (-6)  + (10))  + ( (-0.75) + (0.25))

Here, the integer part  =     ( (-6)  + (10))

Decimal part =   ( (-0.75) + (0.25))

Step-by-step explanation:

Here, the given expression is:    -6.75 + (10.25)

Now, -6.75  = (-6)  +  (-0.75)

Also, (10.25)  = (10)  + (0.25)

So, the expression can be written as

 -6.75 + (10.25)  =  (-6)  +  (-0.75) +  (10)  + (0.25)

                           = ( (-6)  + (10))  + ( (-0.75) + (0.25))

or,   -6.75 + (10.25)    =  ( (-6)  + (10))  + ( (-0.75) + (0.25))

Where the integer part is    ( (-6)  + (10))

and the decimal part is  ( (-0.75) + (0.25))

The sum of 5/2 and 6 times a number equals to 7/2 subtracted from seven times the number find the number
kykrilka [37]

Answer:

1 / 13

Step-by-step explanation:

lets just say the number is 'x'

5/2 + 6x = 7/2 - 7x

6x + 7x = 7/2 - 5/2

13x = 2/2

13x = 1

x = 1/13

proving it

5/2 + 6 × 1/13 = 7/2 - 7 × 1/13

5/2 + 6/13 = 7/2 - 7/13, solving the fraction by finding the L.C.M will result in

77/26 = 77/26

98 points possible
Pavel [41]

Answer:

Step-by-step explanation:

symmetry with respect to y-axis for y=f(x) means f(-x)=f(x)

in this case, y = f(x) = x / (x^2+4)

f(-x) = -x / ((-x)^2+4) = -x / (x^2+4) = -f(x)

so it is not symmetric to y-axis

symmetry with respect to x-axis for x=g(y) means g(-y)=g(y)

in this case, y = x / (x^2+4)

y*(x^2+4) = x

y*x^2 + 4y - x = 0

substitute -y into g(y)

(-y)*x^2 +4(-y) - x = 0

-y*x^2 - 4y - x = 0

y*x^2 + 4y + x = 0

so g(-y) is not equal to g(y)

so it is not symmetric to x-axis
