What is the additive inverse of -5/7x?
Naya [18.7K]
The additive inverse of a is denoted by unary minus: −a (see also § Relation to subtraction below). For example, the additive inverse of 7 is −7, because 7 + (−7) = 0, and the additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0

s344n2d4d5 [400]

Answer:

a). Mileage for carA= \frac{2}{x}  , and mileage for carB=\frac{ 3x+2}{x(x+1)}

b).total mileage for both is similar to average of them= \frac{(mileageA + mileageB)}{2}

=\frac{5x+4}{2x(x+1)}[tex]mil/gal

Step-by-step explanation:

It is given that the distance traveled by car A=2x+2=2(x+1)

And distance traveled by car B= 3x+2

We know the mileage is mile/gallon,

a).So mileage of car A= \frac{distance traveled by car A}{gallos of fuel used}

=\frac{2x+2}{x^2 +x}\\ =\frac{2(x+1)}{x(x+1)} \\=\frac{2}{x}mil/gal

Similarly , the mileage for car B= \frac{distance traveled by car A}{gallons of fuel used}

=\frac{3x+2}{x^2+x} \\=\frac{3x+2}{x(x+1)}mil/gal

b).total mileage for both is similar to average of them= \frac{(mileageA + mileageB)}{2}

=\frac{2x+2}{x(x+1)}+\frac{3x+2}{x(x+1)}\\ =\frac{2x+2+3x+2}{x(x+1)}\\=\frac{5x+4}{x(x+1)}mil/gal

Now divide by 2 for total(average) mileage.

\frac{\frac{5x+4}{x(x+1)} }{2}\\ =\frac{5x+4}{2x(x+1)} mil/gal.

Thus those are the answers.

If f(x)=x^2 and g(x)=1÷2x+3 find g(f(-1))
gogolik [260]

ANSWER

g(f( - 1)) = \frac{1}{5 }

EXPLANATION

The given function is:

f(x) =  {x}^{2}

and

g(x) =  \frac{1}{2x + 3}

g(f(x)) = g( {x}^{2} )

g(f(x)) = \frac{1}{2{x}^{2} + 3 }

To find g(f(-1)), we substitute x=-1, to obtain;

g(f( - 1)) = \frac{1}{2{( - 1)}^{2} + 3 }

We simplify the square in the denominator to get,

g(f( - 1)) = \frac{1}{2+ 3 }

We now add the denominator to obtain;

g(f( - 1)) = \frac{1}{5 }
