Fynjy0 [20]

If the train travels 744 miles in 3 hours then to determine the unit rate the train is traveling per hour you have to divide the miles by the hours, in this case (744 miles)/(3 hours). The final result concludes as 248 miles per hour.

Parallel lines e and f are cut by transversal b. What is the value of x? A.130 B.16 C.164 D.50
Gnesinka [82]

Answer:

A) 130

Step-by-step explanation:

(2x + 18) + y = 180 <--- Is True

(4x - 14) + y = 180 <--- Is True

(2x + 18) + y = y + (4x - 14)  

(2x + 18) = (4x - 14)

2x + 18 = 4x - 14

-2x + 18 = -14

   - 18    - 18

-2x = -32  

x = 16

2(16) + 18 = 50

4(16) - 14 = 50

180 - 50 = 130

Determine the domain of the function (f*g)(x) where f(x) =3x-1/x-4 and g(x) =x+1/x
BARSIC [14]

Answer:

Domain = R- {0,4}

Step-by-step explanation:

f(x) =\frac{3x-1}{x-4}

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

(f*g)(x)=\frac{3x-1}{x-4} \times \frac{x+1}{x}

(f*g)(x)=\frac{(3x-1)(x+1)}{(x-4)(x)}

In order to function (f*g)x to be defined , the Denominator must not be equal to zero.

Hence

x ≠ 0

(x-4) ≠ 0 ⇒ x≠4

Hence (f*g)x is defined for all values of x except 0 and 4

Hence Domain = R- {0,4}
