A mechanic charged $220.28 to repair a car. The price included charges for 3 hours of labor and $126.53 for parts. How much does
jasenka [17]
Lets x is the labor charges per hour
3x + 126.53 = 220.28

3x = 220.28 - 126.53
3x = 93.75
x = 93.75  /  3
x = 31.25

answer:  $31.25 per hour charged for labor

Determine the domain of the function (f o g)(x) where f(x)= 3/x+2 and g=5/x.
vitfil [10]

Answer:

The Domain is all real values of x except x = 0 and x = -2.5.

Step-by-step explanation:

I am assuming that f(x) = 3/(x + 2).

(f o g)x is found by substituting  5/x for the x in 3/(x + 2).

(f o g) x = 3/ ( 5/x + 2)

= 3 / ( 5+2x) / x

= 3x / (5 + 2x).

When finding the domain you  first check for values of x which make g(x) undefined then values of x which make (f o g)(x) undefined.

x = 0 makes  g(x) = 5/0 so it is undefined and  x = -2.5 makes g o f undefined also.

I have 3/5 marbles. Emily gave me 4/3 marble. how many marbles do I have?
igomit [66]
If you have 3/5 marbles and you got 4/3more marbles then all you have to do is:3/5 x 3/3 and get 9/15.For 4/3 you multiply 4/3 x 5/5 and get 20/15.You simplify this and get 1 5/15.Now all you do is add them and get 1 14/15. Hope this helped you :-).

Write the equation of the line, in slope-intercept form, with the
IrinaVladis [17]

Answer:

y = -x -1

Step-by-step explanation:

x1= 0, y1= -1

slope =  \frac{x - x1}{y - y1}  =  \frac{x - 0}{y - ( - 1)}  =  \frac{x}{y + 1}

-1 = x/(y+1)

-1 (y+1) = x

y+1 = -x

y= -x -1
